Facial nerve paralysis, also called "Facial palsy" may be classified into the peripheral type and the central type. Peripheral type is due mainly to facial neuritis induced by exposure to cold and/or wind. Onset is sudden, with pain in the posterior ear region followed by paralysis of the facial muscles of expression, disappearance of forehead creases, and inability to shut the eye. The nasal labial groove is shallow, the mouth is drawn towards the healthy side. There may be loss of the sense of taste in the anterior two-thirds of the tongue on the affected side and acoustic hypersensitivity. Where the disease persists for a long time, the facial muscles of the affected side may become contracted, with the corner of the mouth twisted towards the affected side. There may be muscular twitching and an uncomfortable sensation of stiffness in the face.
Facial paralysis of the central type is caused mainly by cerebral vascular disease or cerebral tumor. Symptoms are limited to the lower portion of the face where the muscles are paralysed. The forehead creases and shutting of the eyes are not affected, but there may be hemiplegia or paralysis of the upper extremities.
