Facial paralysis after salivary gland surgery is muscle weakness and loss of movement that occurs when the facial nerve, which passes directly through the parotid gland located in front of the ear, is affected during the surgical treatment of tumors or masses arising in this gland. In parotidectomy operations, which are among the most delicate procedures in the head and neck region, this condition develops when the electrical transmission to the main nerve network controlling our facial expressions is interrupted while the diseased tissue is being removed. Also known as facial paralysis, this condition is characterized by a disruption in the biological communication between the brain and the facial muscles and is an important clinical complication requiring direct intervention after surgery.<\/p>\n
| What is facial paralysis after salivary gland surgery?<\/span><\/td>\n | It is the development of loss of movement or weakness on one side of the face due to involvement of the facial nerve, which moves the facial muscles, after salivary gland surgery, particularly surgery of the parotid gland located in front of the ear. This condition may be temporary or permanent.<\/span><\/td>\n<\/tr>\n| Why does it occur?<\/span><\/td>\n | It may develop as a result of stretching of the facial nerve during surgery, compression caused by edema, manipulation of the surrounding tissues, partial damage to the nerve, or the inability to preserve the nerve because the tumor is close to or has invaded the nerve.<\/span><\/td>\n<\/tr>\n | After which operations can it occur?<\/span><\/td>\n | It is most commonly seen after parotid gland surgery. Although certain branches of the facial nerve may be affected during submandibular salivary gland surgery, complete facial paralysis is less common.<\/span><\/td>\n<\/tr>\n | What is temporary facial paralysis?<\/span><\/td>\n | It is a loss of function caused by edema or stretching during surgery despite preservation of the nerve structure. Improvement is seen within weeks or months in most patients.<\/span><\/td>\n<\/tr>\n | What is permanent facial paralysis?<\/span><\/td>\n | It is permanent loss of function that develops when the nerve is severely damaged or when the nerve must be removed because of the tumor. Recovery may be limited, and advanced treatments may be required.<\/span><\/td>\n<\/tr>\n | Symptoms<\/span><\/td>\n | Drooping of the corner of the mouth, inability to close the eye completely, asymmetry when smiling, inability to wrinkle the forehead, weakness in lip movements, leakage of food and liquids from the corner of the mouth while eating, and mild speech impairment may occur.<\/span><\/td>\n<\/tr>\n | Which facial movements may be affected?<\/span><\/td>\n | Voluntary facial movements such as raising the eyebrows, closing the eyes, moving the nostrils, smiling, pursing the lips, and puffing out the cheeks may be affected.<\/span><\/td>\n<\/tr>\n | How is the diagnosis evaluated?<\/span><\/td>\n | The function of the facial muscles is evaluated through postoperative neurological and physical examination. When necessary, nerve function may be assessed with tests such as electromyography (EMG).<\/span><\/td>\n<\/tr>\n | Recovery time<\/span><\/td>\n | In temporary nerve involvement, recovery may vary from several weeks to several months. The healing time of the nerve depends on the degree of damage and may take longer in some cases.<\/span><\/td>\n<\/tr>\n | Treatment approach<\/span><\/td>\n | Treatment is planned according to the degree of nerve damage. Eye protection, physical therapy, facial exercises, and medication when considered necessary may be applied. Reconstructive surgical options may be evaluated in cases of permanent damage.<\/span><\/td>\n<\/tr>\n | Why is eye care important?<\/span><\/td>\n | If the eye cannot close completely, the cornea may become dry and damaged. Therefore, artificial tear drops, eye ointments, and closing the eye at night when necessary may be recommended.<\/span><\/td>\n<\/tr>\n | Physical therapy and rehabilitation<\/span><\/td>\n | Facial exercises and rehabilitation programs may be applied to support the coordination of the facial muscles, reduce muscle stiffness, and help restore function.<\/span><\/td>\n<\/tr>\n | Possible complications<\/span><\/td>\n | Permanent facial asymmetry, involuntary muscle movements (synkinesis), dry eye, corneal damage, difficulties with speech and eating, and psychological effects may develop.<\/span><\/td>\n<\/tr>\n | When should a doctor be consulted?<\/span><\/td>\n | Evaluation is required if unexpected worsening of facial movements, severe dry eye, eye pain or changes in vision, redness or discharge at the wound site, fever, or severe pain develops.<\/span><\/td>\n<\/tr>\n | What should be considered at home?<\/span><\/td>\n | It is important not to neglect eye care, to follow the care instructions for the surgical area, to perform the recommended facial exercises regularly, to use medications in accordance with the prescription, and not to miss follow-up appointments.<\/span><\/td>\n<\/tr>\n | Prognosis<\/span><\/td>\n | The prognosis depends on the degree of nerve damage and the reason for the surgery. If the nerve is only temporarily affected, the likelihood of recovery is high. Permanent loss of function may occur when the nerve is severely damaged or removed, and additional treatments may be required.<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n | |
