Complete facial palsy is not a clear medical term and may refer to peripheral facial palsy, which usually refers to symptoms of paralysis of the facial muscles caused by damage to the nerves in the affected face. The cause of complete facial paralysis is unknown, and is usually associated with viral and bacterial infections and cold exposure to the face. Patients usually experience loss of frontal wrinkles, incomplete eyelid closure, drooping of the corners of the mouth, shallow nasolabial folds, leakage of air from the corners of the mouth, and sideways tilting of the corners of the mouth, and in more severe cases, may also experience auditory sensitivities, gustatory disturbances, and impaired lacrimal secretion. Complete facial paralysis can be treated with dexamethasone, prednisone tablets and hydrocortisone tablets to reduce local edema, and sublingual nerve surgery and paracortical nerve anastomosis can be performed if medication is not effective. Patients with facial paralysis should seek medical advice from a doctor who is specialized in the treatment of facial paralysis.
