Facial neuritis should be treated by the Department of Neurology, but after the acute phase, physiotherapy can be performed at the Rehabilitation Department. Facial neuritis is caused by non-specific inflammation of the facial nerve within the stylomastoid foramen, leading to peripheral facial paralysis. The exact cause is currently unclear, but it is believed to be related to optic nerve viral infections. It usually occurs after exposure to cold and upper respiratory infections, and can occur at any age, most commonly between 20 and 40 years, with a higher incidence in males than females. It starts acutely, peaking within a few hours or days, mainly presenting as paralysis of the facial expression muscles, disappearance of forehead lines, inability to frown or wrinkle the forehead, and inability to close the eyelids or incomplete closure. Therefore, during the acute phase, treatment in the Department of Neurology is necessary, and rehabilitation treatment can be sought after the acute phase in the Rehabilitation Department.
