Facial Paralysis: Causes, Early Symptoms, Diagnosis, and Treatment

Facial paralysis is a condition that occurs as a result of damage to or inflammation of the facial nerve (the 7th cranial nerve), which controls the facial expressions on our face. Known medically as “facial paralysis,” this condition manifests as weakness or complete immobility of the muscles on one side of the face. Patients usually describe the shock they experience when they wake up in the morning and look in the mirror as follows: “Half of my face has drooped downward, when I try to smile my mouth becomes crooked, and I cannot close my eye.”

Facial paralysis is not merely a muscle weakness; it is almost like temporarily losing a part of our identity and social presence. Consider that our facial expressions are the most direct interpreters of our emotions. We smile when we are happy and frown when we are sad. Losing these expressions closes an important channel of our emotional communication. My patients often complain, “Doctor, people cannot understand what I am thinking when they look at me. While I think I am smiling, the person in front of me thinks I am frowning.”

The effects of facial paralysis on daily life are far more extensive than expected. Drops leaking from the edge of the cup while drinking tea, food accumulating in one corner of the mouth while eating, certain letters not coming out clearly while speaking… These are practical difficulties that patients constantly have to face. Perhaps the most uncomfortable one is the constant dryness, burning, and stinging sensation caused by the inability to close the eyelid completely. Patients describe this condition as, “It feels as though sand is constantly getting into my eye.”

The onset of facial paralysis is unique to the individual, just like our fingerprints. Some patients suddenly wake up with complete paralysis in the morning—while everything was normal when they went to bed the previous night, half of their face seems to be “frozen” when they wake up. In others, it begins with a mild sensation of numbness or tightness and then gradually progresses to complete paralysis over hours or days. This difference depends on the underlying cause and the degree of nerve damage.

Facial paralysis always raises the same question in the minds of patients: “Will my face return to its previous state?” The answer to this question varies according to the cause and severity of the paralysis and the time at which treatment is started. In conditions caused by viral factors such as Bell’s palsy, approximately 70–85% of patients show complete or nearly complete recovery within 3–6 months. However, this process, like the flow of a river, progresses at its own natural course and speed—it can neither be accelerated greatly nor predicted with certainty.

Definition	It is a condition of muscle weakness or paralysis developing on one side of the face or, rarely, on both sides as a result of damage to or loss of function of the facial nerve that moves the facial muscles.
Most Common Type	Bell’s palsy (sudden-onset peripheral facial paralysis of unknown exact cause) is the most common type of facial paralysis.
Other Causes	Stroke, head trauma, ear infections, Lyme disease, Ramsay Hunt syndrome (shingles), tumors, congenital diseases, diabetes, neurological diseases, and surgical procedures.
Who Is Affected?	It can occur at any age. It may be seen more frequently in people with diabetes, pregnant women (especially in the last trimester), those who have had an upper respiratory tract infection, and individuals with weakened immune systems.
Symptoms	Sudden weakness on one side of the face, drooping at the corner of the mouth, inability to close the eyelid, inability to wrinkle the forehead, impaired smiling, drooling, mild speech impairment, changes in the sense of taste, pain around the ear, sensitivity to sound, dry eyes, or excessive tearing.
Difference from Stroke	In peripheral facial paralysis, the forehead muscles are generally also affected. In stroke, however, the forehead muscles are usually preserved, and arm or leg weakness, speech impairment, or changes in consciousness may accompany facial paralysis. The possibility of stroke must always be evaluated in sudden-onset facial paralysis symptoms.
Diagnostic Methods	Detailed neurological examination, ear-nose-throat evaluation, MRI or CT when necessary, blood tests, electromyography (EMG), hearing tests, and examinations directed toward the underlying cause.
Treatment	It is planned according to the cause. Corticosteroid treatment is frequently administered in the early period in Bell’s palsy. Antiviral medications may be added in some patients. Eye-protective drops and ointments, eye-closing methods, physical therapy, facial exercises, and surgical options when necessary may be considered.
Eye Care	If the eyelid cannot close, artificial tear drops, nighttime eye ointment, an eye patch, or protective closure methods are used in an effort to prevent corneal damage.
Physical Therapy	Exercises that support the facial muscles, massage, neuromuscular retraining, and rehabilitation under specialist supervision may be applied.
Recovery Period	In Bell’s palsy, many patients begin to improve within a few weeks and may recover to a large extent within 3–6 months. In some patients, recovery may take longer or permanent effects may develop.
Possible Complications	Permanent facial muscle weakness, involuntary muscle movements (synkinesis), eye dryness and corneal damage, muscle stiffness, and aesthetic and psychological effects.
When Should Emergency Care Be Sought?	If sudden-onset facial paralysis is accompanied by weakness in the arm or leg, speech impairment, severe headache, changes in consciousness, vision loss, or balance problems, urgent medical evaluation is required.
Prevention	Although not all causes can be prevented, diabetes control, appropriate treatment of infections, protection from head trauma, and general health check-ups may help reduce the risk.
Prognosis	It varies according to the underlying cause. Significant improvement is seen in the majority of patients with Bell’s palsy with appropriate and early treatment.

What Is Facial Paralysis and What Is the Anatomical Journey of the Facial Nerve?

The facial nerve begins in the brainstem and sets out on a very long, complex, and equally challenging journey to reach the facial muscles. This nerve is not made up of a single strand; it is like a complex cable network containing approximately ten thousand extremely fine nerve fibers. Just before leaving the skull and spreading into the facial region, it must pass through an extremely narrow bony canal inside the temporal bone, namely the fallopian canal.

The greatest risk factor underlying facial paralysis is the journey of the nerve through this narrow tunnel. When this nerve tissue traveling through a millimetric canal swells due to any infection, inflammation, or trauma, it cannot expand outward. Because the bony walls are not flexible, the swollen nerve begins to compress itself. This pressure causes the extremely fine and sensitive capillaries that nourish the nerve to be crushed, blood flow to become impaired, and ultimately the electrical signals sent by the brain to fail to reach the target muscles in the face. The facial expression muscles that do not receive electrical stimulation immediately stop contracting and moving. After emerging in front of the ear, the facial nerve divides into five main branches toward the forehead, around the eyes, cheeks, corners of the mouth, and neck area, directing all facial movements like the conductor of an orchestra.

What Causes Facial Paralysis and Which Conditions Trigger This Picture?

There are many different factors that can damage the nerve responsible for moving the facial muscles. These factors may sometimes be an external physical blow, sometimes an infection developing within the body, and sometimes a congenital developmental deficiency. Any adverse event encountered along the long course of the nerve from inside the brain to the most distant points of the face has the potential to result in paralysis of the facial muscles. The location and severity of the damage and the speed of onset vary greatly according to the underlying cause.

The main groups of causes are listed below:

• Infections
• Traumatic injuries
• Benign or malignant tumors
• Complications of surgical operations
• Metabolic and vascular diseases
• Congenital anatomical anomalies

What Place Does Bell’s Palsy Hold Among the Causes of Facial Paralysis?

When all facial paralysis cases are examined, the condition encountered in a very large proportion of patients, approximately eighty percent, is called Bell’s palsy in the medical literature. For many years, the medical world classified this condition as “idiopathic,” meaning a disease whose cause could not be identified. However, today, developing scientific research and investigations at the genetic level strongly reveal that viruses are the greatest suspected factor behind this condition. In particular, Herpes Simplex Virus (HSV-1), widely known among the public as the cold sore virus, is considered the principal actor in this condition.

Once this virus enters the human body, the immune system cannot completely destroy it; the virus settles in the deepest parts of the nerve ganglia and may remain in a deep sleep for years or even decades. During periods when a person is exposed to extreme stress, becomes very tired, experiences a severe infection, is exposed to intense cold or wind, or when the immune system is suppressed for any reason, this virus suddenly awakens from its sleep. Reactivation of the virus directly initiates an aggressive infection and inflammatory process in the protective sheath around the facial nerve. The inflamed nerve rapidly swells, becomes severely compressed within the bony canal through which it passes, and the paralysis picture usually develops within a few hours. Patients generally realize with great fear that they went to sleep completely normally in the evening but cannot move one side of their face when they look in the mirror in the morning.

How Does Ramsay Hunt Syndrome Affect the Facial Paralysis Picture?

Another important and clinically more severe and painful viral cause of facial paralysis is the medical condition known as Ramsay Hunt Syndrome. The underlying cause of this disease is the Varicella Zoster virus, which causes chickenpox during childhood or shingles encountered in adulthood. Just like the herpes virus, the chickenpox virus tends to hide from the immune system for years and continue living in nerve cells. This virus, which suddenly awakens in a sensory portion of the facial nerve, creates a much more dramatic picture with greater tissue destruction and severe damage compared with Bell’s palsy.

In this syndrome, patients do not encounter only weakness or paralysis in the facial muscles. Numbness in the face is generally accompanied by fluid-filled, extremely painful, pimple-like rashes and blisters inside the ear, on the auricle, or in the palate region. In addition, because the nerve network around the ear is also inflamed, severe throbbing ear pain, intense dizziness in which the surroundings seem to spin rapidly due to involvement of the balance nerve (vertigo), nausea, and sometimes temporary or permanent hearing loss are among the complaints that challenge the patient. Because the structural damage caused by the virus to the facial nerve in Ramsay Hunt syndrome is deeper and more destructive, the risk of leaving permanent asymmetry or incomplete recovery is quite high.

How Do Traumas and Surgical Procedures Appear as Causes of Facial Paralysis?

Apart from inflammatory conditions created by viruses within the nerve, every external factor that disrupts the physical and anatomical integrity of the facial nerve is also a direct and immediate cause of facial paralysis. In high-speed traffic accidents, serious fractures of the skull, especially in the temporal bone behind the ear, may cause the nerve to be crushed, stretched, or completely severed as though cut with scissors inside the bony tunnel. Similarly, glass cuts, knife injuries, or severe blows to the facial area may directly tear the nerve branches beneath the skin and cause the muscles in that region to become paralyzed.
In addition, nerve damage described in medicine as iatrogenic, meaning damage that develops during a medical necessity, intervention, or major surgical operation, also occupies an important and challenging position. The facial nerve passes directly through the center of the parotid gland, which is located in front of the ear and at the angle of the jaw and is responsible for saliva production, dividing into five separate branches like the fingers of a hand. During surgical operations for benign or malignant tumors developing in the parotid gland that must be removed, doctors work meticulously for hours under surgical microscopes to separate these delicate nerve branches from the tumor tissue. In cases of aggressive cancer in which the tumor completely surrounds the nerve like an octopus, it may be necessary to sacrifice part of the facial nerve in order to save the patient’s life and completely eliminate the disease from the body. The same situation may also occur during operations for some large masses developing deep within the brain.

What Causes Congenital Facial Paralysis and With Which Syndromes Is It Seen?

Although it is a very rare condition, some babies have facial paralysis from the moment they first open their eyes to the world. This condition generally results from complex genetic mutations, vascular circulation problems, or developmental arrests occurring during the embryological development stages of the baby in the womb. The most striking and well-known example of congenital facial paralysis in the medical world is Moebius Syndrome. In this complex syndrome, the nuclear regions located in the brainstem, the lowest part of the brain, which form the starting center of the facial nerve within the brain, have either failed to develop at all from birth or remain incomplete. In addition, the sixth cranial nerve, which generally allows the eye to turn outward, is also affected by this developmental deficiency.

Babies with Moebius syndrome have a motionless and expressionless facial appearance known medically as a “mask face” from birth. The most basic reactions inherent in human nature, namely crying when in pain, showing surprise, or smiling when happy, do not produce any muscle movement in their faces. These children cannot wrinkle their foreheads, purse their lips as though giving a kiss, or move their eyes comfortably from side to side. Because the muscles do not function, they experience feeding problems carrying life-threatening risks during infancy, such as very weak sucking reflexes, inability to swallow milk because complete lip sealing cannot be achieved, and fluid entering the lungs.

What Are the Symptoms of Facial Paralysis and How Is the Damage Recognized?

The symptoms of facial paralysis generally appear not through a slow process lasting months but with an extremely sudden, dramatic speed that drives the patient into panic within hours or a few days. Depending on the anatomical level of the damage, how severely the nerve is compressed, and whether communication loss is complete or partial, the clinical picture may differ greatly from one patient to another. The most fundamental and striking visible problem is the complete loss, even at rest, of the aesthetic harmony, namely symmetry, between the right and left halves of the face. The weak muscles on the affected side succumb to gravity and collapse downward, creating pronounced asymmetry in the face.

The main symptoms that occur can be summarized as follows:

• Severe facial asymmetry
• Drooping eyelid
• Complete or partial immobility
• Loss of expression and facial movement
• Drying of the corneal surface
• Pronounced slurring of speech
• Leakage of fluid from the corner of the mouth
• Decreased sense of taste on the tongue

The conditions indicated by these items are serious functional losses that immediately disrupt the patient’s most ordinary daily activities. When the patient stands in front of a mirror and tries to raise an eyebrow as though surprised, only the forehead on the healthy side wrinkles, while the paralyzed side remains flat as though frozen. When the patient wants to smile at happy news, the corner of the mouth is pulled strongly toward the side of the functioning powerful muscles, while the paralyzed side remains motionless and unresponsive, creating a very pronounced and disturbing distortion of the face. Actions requiring complete and flawless closure of the lips, such as whistling, drinking water through a straw, blowing air into a balloon, or inflating the cheeks to create pressure inside the mouth, become completely impossible.

Why Is Eye Health the Most Urgent Issue Among the Symptoms of Facial Paralysis?

Although many people perceive facial paralysis only as an externally visible aesthetic deformity, asymmetry in the smile, or deviation of the face, for medical professionals who approach this matter scientifically, the single most urgent and dangerous condition in this picture, with the potential to cause irreversible permanent consequences, is eye health. The circular muscle that allows our upper eyelid to close like a curtain and enables us to blink involuntarily (orbicularis oculi) receives all of its power and command directly from the facial nerve. When the nerve becomes paralyzed and electrical conduction stops, this muscle can no longer perform its function, and the upper eyelid cannot descend to cover the eye. This condition in which the eye remains continuously open, called lagophthalmos in medical terminology, leaves the highly valuable and sensitive eye tissue completely unprotected against all dangers of the outside world.

Healthy people blink thousands of times throughout the day, often without even realizing it. This blinking action works like the windshield wipers of a car, spreading the tear film smoothly and evenly over the cornea, the transparent outermost layer of the eye, thereby constantly cleaning and moisturizing the eye. However, when the eyelid cannot close mechanically in paralysis, tears cannot be distributed across the surface, and the eyeball remains in direct contact with open air, harsh wind, dry air blown by air conditioners, and dust particles. Within a very short time, the cornea dries out, its cellular integrity deteriorates, it becomes red and severely irritated, and a serious process of cellular destruction called exposure keratopathy begins. If simple but vital protective measures are not taken immediately, the eye is not externally moisturized, and it is not physically protected in a closed position, this severe dryness may cause deep wounds (ulcers) to develop on the cornea, infections to spread into the eye, and ultimately disasters extending to complete blindness due to corneal perforation.

How Does Facial Paralysis Impair Chewing and Speech Functions?

Anatomically, the facial nerve controls not only the muscles that wrinkle the forehead and surround the eyes but also numerous fine and complex muscle groups surrounding the lips, forming the walls of the cheeks, and extending down to the jawline. The sudden loss of electrical support and function in these finely tuned muscles transforms eating at the family table and speaking fluently with loved ones, the most frequently repeated basic activities of our daily lives, into a great ordeal and a cause of social isolation.

In particular, the muscle forming the cheek wall (buccinator) is an extremely key muscle that prevents bites of food from escaping into the cheek cavity while we chew hard food and continuously holds the food like a press between the grinding surfaces of the teeth. Because this cheek muscle completely relaxes and loses its tone in paralysis, food particles accumulate in the space between the teeth and the cheek on the paralyzed side while the patient chews foods such as bread or meat. Because the patient cannot contract the muscles in that area and push the food back onto the tongue, they must provide mechanical support by pressing the cheek from the outside with the hand. In addition, because of drooping at the corner of the mouth and the inability of the lip muscles to close completely, namely impaired lip sealing, bringing a glass to the mouth to drink water or drinking soup becomes very difficult; the consumed liquids leak from the uncontrolled edge of the mouth and spill onto clothing. During speech, the pronunciation of lip consonants such as B, P, M, and V, which are formed by firm contact between the upper and lower lips, is severely impaired, and pronounced slurring, in which the patient rolls the words, emerges in speech. In addition, because the nerve fibers carrying the sense of taste to the brain also pass through this canal, the taste of food is also largely lost.

How Can the Difference Between Central and Peripheral Facial Paralysis Be Understood?

When an individual presents to the emergency department after waking up in the morning with pronounced facial deviation, drooping of the mouth, and an inability to move, the first and most critical duty of physicians is to determine correctly where the true source of this paralysis lies. This is because deviation of the face may be caused not only by an innocent nerve compression but may also be the first major warning sign of a central stroke that directly threatens life within seconds, such as a brain hemorrhage, a clot traveling to the brain, or blockage of the cerebral vessels. In conditions referred to as peripheral facial paralysis, however, the problem lies entirely in the nerve pathway outside the brain.

Distinguishing these two major and very different conditions is based on an extremely simple and clear rule during physical examination for experienced eyes. The lower face, cheeks, and corner of the mouth of a patient whose face has deviated due to damage within the brain (stroke) droop; however, when the patient is asked to raise an eyebrow, the muscles in the forehead region are still seen to continue moving perfectly. The patient can wrinkle the forehead comfortably. The remarkable anatomical reason for this is that in human design, the forehead region receives redundant bilateral nerve support from both hemispheres of the brain. Even if one cerebral hemisphere is damaged, the other continues to move the forehead. However, if the damage occurs directly in the main trunk of the facial nerve emerging from behind the ear (peripheral), electrical conduction is completely interrupted, and the right or left half of the face remains entirely motionless from top to bottom, from the uppermost forehead to the lowest part of the chin.

How Should the Initial Intervention Be Performed in Patients Experiencing Facial Paralysis?

The first days and weeks after asymmetry and weakness are noticed in the face are literally of vital importance for the ultimate success of the treatment process. This initial period is called the acute phase. Early diagnosis and extremely rapid medical intervention are the most effective known methods for quickly reducing the edema (swelling) developing in the nerve sheath inside the very narrow bony canal before it deprives the nerve cells of oxygen and causes permanent death. Medical protocols generally aim to begin high-dose cortisone (methylprednisolone) treatment under physician supervision within the first 72 hours. The primary purpose of cortisone here is to suppress inflammation, reduce the pressure in the tunnel where the nerve is compressed, and help the crushed vessels restore blood flow.

While medical treatment is initiated in this acute phase, the most critical responsibility that the patient must personally undertake is the complete implementation of the previously mentioned eye-protection strategies.

Eye-protection measures basically include the following.

• Artificial tear drops
• Intensive moisturizing ointments
• Hypoallergenic medical tapes
• Large protective glasses

During waking hours, protective tear drops should be applied to the eye every hour to support the continuously drying cornea, while gel-like moisturizing ointments that remain on the eye surface for longer should be applied when going to sleep at night. Because the eyelid will not close by itself during sleep, it should be completely fixed in the closed position from the outside with skin-friendly medical tape, and an artificial moisture chamber should be created until morning.

Which Methods Does Plastic Surgery Use in the Treatment of Facial Paralysis?

While many patients with facial paralysis recover completely within a few months with appropriate medical treatments initiated in the early period, there is also a large group of patients who permanently lose movement and must live with facial paralysis for life as a result of severe trauma, mandatory tumor surgery, or severe viral infections causing very serious nerve damage. It is precisely at the point where this hopelessness begins that modern plastic, aesthetic, and reconstructive surgery comes into play. In these difficult and complex conditions in which the facial nerve has permanently lost its function and the muscles cannot receive any movement commands, all procedures requiring the highest level of technological and surgical skill are generally called “Facial Reanimation,” meaning the art of reviving the face through surgical methods.

The aim of plastic surgery specialists throughout this long journey is not merely to turn the face into an aesthetically symmetrical mask. The primary and most important goal is to secure vision by allowing the eyelid to close dynamically, restore clear speech and healthy chewing functions by correcting the drooping corner of the mouth, and ultimately enable the patient to reflect the emotions trapped inside for years on the face again and confidently rejoin social life by smiling freely as before.

What Are Early-Stage Facial Paralysis Surgeries?

If many years have not yet passed since the onset of facial paralysis, the first eighteen months are generally considered the “early period” clinically. This time limit has a very critical medical meaning: The facial expression muscles that do not receive the vital electrical signal that should come from the brain have not yet completely wasted away on their own, have not undergone cellular degeneration called atrophy, and have not turned into fibrotic and rigid tissue. The muscles are almost in a deep sleep and preserve their potential for vitality. If a new nerve pathway, a new electrical cable, can be drawn from outside to these sleeping muscles through modern microsurgical methods, these muscles can awaken and begin working strongly again.

The main philosophy of surgeries performed during this period is the repair of nerve tissue. For example, if the facial nerve has been cleanly cut or severed during an accident or surgical intervention, the ideal procedure is to bring the severed nerve ends together and suture them under high-magnification surgical microscopes using threads thinner than a strand of hair (primary repair). However, if a gap remains between the severed ends due to the passage of time or the severity of the trauma, a replacement piece must be placed between them instead of forcefully pulling the nerve. A segment is cut and taken from the long sural nerve, generally located at the back of the leg, which can be sacrificed without causing functional loss in the body. This healthy nerve segment is used as a patch (graft) between the severed ends of the facial nerve through microsurgery, thereby bridging the gap.

How Is Muscle Transplantation Performed in Late-Stage Facial Paralysis Cases?

If more than two or three years have passed since the patient experienced facial paralysis, it is now biologically impossible to awaken those sleeping muscles by connecting a nerve. This is because the delicate facial expression muscles that have remained immobile and unstimulated for years have now completely wasted away, been replaced by connective tissue, and permanently and irreversibly lost their ability to contract and produce movement. At this delayed stage, even if the most perfectly functioning nerve in the world were brought and connected to the patient, no biological motor would remain to receive that electricity and convert it into movement. Therefore, plastic surgeons change strategy at this stage and perform an operation called “dynamic reanimation,” in which entirely new, fully living and healthy muscle tissue with an excellent ability to contract is transferred from a completely different part of the body to the paralyzed facial region.

The gold standard of these remarkable operations is “free gracilis muscle transfer” surgery. The gracilis muscle, a thin and long muscle generally located in the inner part of the thigh, is preferred because its removal does not cause any noticeable deficiency or weakness in walking or running functions. During the operation, this muscle is meticulously freed and completely separated from the leg together with the artery and vein that keep it alive and the motor nerve that allows it to move. This new muscle tissue is then transferred to the patient’s immobile facial region using microsurgical methods. The vessels of the muscle are sutured under a microscope to healthy vessels in the face or neck region, allowing the muscle to receive blood again and survive. Then, one end of the muscle is firmly attached to the corner of the lips and the other end at the level of the cheekbone, thereby constructing a brand-new “smile elevator” for the patient’s face.

How Does Masseter Nerve Transfer Work in the Treatment of Facial Paralysis?

When a new muscle (gracilis) is transferred from the thigh to the face or when external nerve support is planned before the muscles have died, this new system must be connected to a healthy electrical source under the control of the brain, namely an active motor nerve, so that it knows when to move and under which command to contract. Because the original facial nerve does not function, surgeons choose to “borrow” the power of healthy motor nerves located in neighboring anatomical regions and performing different functions. This procedure forms the brain of facial reanimation.

For this purpose, the most frequently and reliably used nerve worldwide is the masseteric nerve.

The features that make the masseteric nerve so preferable are as follows:

• Strong motor capacity
• Very rapid contraction response
• Anatomical proximity to the target muscles
• High postoperative adaptation

The masseter is one of the strongest muscles in the body, allowing us to close the lower jaw upward and crush food while chewing. Only a small branch of the nerve controlling this remarkable strength is surgically sacrificed and sutured to the new system connected to the paralyzed face (nerve transfer). After a long period of tissue healing, when the muscle begins to function, every time the patient consciously clenches the jaw, the brain transmits this command to the new muscle at the corner of the mouth as well, and the muscle pulls upward, causing the lips to curve outward, namely producing a smile. Initially, the patient must consciously think about clenching the teeth whenever wanting to smile. However, thanks to the remarkable adaptive ability of the human brain known as neuroplasticity, the brain permanently learns this new shortcut through regular practice. Months later, patients can smile at the person in front of them in a completely natural, reflexive, and spontaneous way simply because they feel happy, without ever thinking about clenching the teeth or chewing.

Why Is a Gold Weight Placed in the Eyelid After Facial Paralysis?

Gracilis muscle transfers and masseteric nerve transfers generally focus on restoring the lower half of the face, lifting the drooping lips, and recreating the longed-for smile. However, because the opening around the eye poses a much more urgent danger that may lead to blindness than all these aesthetic concerns, it must be solved with a completely different surgical approach. In cases where the eyelid has lost its function, “gold weight implantation,” performed to provide passive but highly reliable closure, is one of the most elegant and protective solutions offered by plastic surgery by combining technological knowledge with the laws of gravity.

In this practical but life-saving procedure, which can often be performed under local anesthesia while speaking with the patient, a small incision is made directly in the fold of the upper eyelid. A small plate of pure gold, whose weight has been specially determined in advance according to the degree of the patient’s eye opening and the structure of the eyelid, is placed and sutured directly onto the cartilage-like tissue called the tarsal plate, which forms the framework of the eyelid. The great medical secret behind the use of gold is that it demonstrates excellent biological compatibility with the body’s immune system, never causes an allergic reaction or tissue rejection, and has an extremely high density. Thanks to this high density, even a very thin and externally invisible small piece can provide sufficient pulling force. The logic of the system is simple: Because the muscle that opens the patient’s eye is controlled by a completely different nerve (the third cranial nerve), it remains intact, and the patient can open the eye comfortably. However, when the patient becomes sleepy or wants to blink involuntarily, the eye-opening muscle relaxes, and at that moment the force of gravity created by the gold comes into play and pulls the upper eyelid downward like a roller blind. In this way, the eye closes completely and perfectly and is protected from dryness.

What Are Static Suspension Methods in Cases Where Movement Does Not Return?

In some cases, the advanced age of patients, the presence of serious additional diseases such as heart disease or diabetes, and the risks associated with general anesthesia may make it dangerous for them to undergo very complex microsurgical operations lasting many hours. Sometimes, patients who do not prefer a recovery process lasting months seek faster and more practical solutions whose effects they can see immediately upon leaving the operating table. In such cases where the movement of the facial muscles cannot be restored dynamically and a new muscle is not transferred, “static reanimation” methods are used at least to correct the tired appearance of the face at rest, severe asymmetry, and aesthetic imbalance.

The main suspension materials used are listed below.

• Healthy muscle fascia taken from the body (fascia lata)
• Strong synthetic threads produced for medical purposes
• Special suspension meshes compatible with tissue

Using these durable materials, the surgeon enters through small incisions. The corner of the mouth and cheek tissue that have completely collapsed downward over the years due to paralysis, drooped, and given the patient a sad expression are suspended like a tent and firmly fixed to a healthy area above, generally the cheekbone or the firm tissues in the temple region. Although these procedures do not provide the patient with a new facial expression, they greatly prevent the mouth from deviating excessively to one side while speaking or eating. The midline of the face is balanced, lip asymmetry is corrected, and a much more lifted and aesthetically acceptable appearance is achieved.

How Is Botox Used for Involuntary Contractions (Synkinesis) After Facial Paralysis?

During the months when facial paralysis slowly begins to improve after severe damage, the crushed nerve fibers may not always find the correct path while growing and extending again. During the regeneration process, some fibers may lose their direction and connect not to their original target sites but to completely different neighboring muscles. In this chaotic situation described medically as misdirection, when the brain sends a command to one muscle group, other muscles that have been mistakenly connected there also receive electrical stimulation and contract forcefully in an uncontrolled manner. These involuntary and exhausting contractions are called synkinesis. For example, when the patient simply wants to blink, the corner of the mouth twitches; while smiling, the neck muscles tighten like cords, or while chewing food, the eyes involuntarily close and water.

Synkinesis is a condition as troublesome as the paralysis itself because of both the aesthetic deformity it creates and the constant tightness, cramps, and contraction pain it causes in the face. At precisely this point, botulinum toxin, namely Botox, generally known in beauty procedures as a wrinkle-reducing treatment, enters the scene as a remarkable medical treatment tool. Botox medication is injected with very fine needles in millimetric amounts directly into the problematic muscles that contract spontaneously and excessively due to synkinesis. The medication temporarily and completely blocks the incorrect transmission passing from the nerve ending to the muscle, causing the muscle in that area to become paralyzed and relaxed. In this way, involuntary blinking stops and pulling in the neck is relieved. In addition, because the muscles on the healthy side face no resistance, they pull the face forcefully toward their own side. Plastic surgeons also apply controlled Botox to the muscles on the healthy side that pull excessively, slightly reducing their strength and balancing both sides of the face like a scale to achieve a much more aesthetic and peaceful symmetry.
