The clinical symptoms of facial neuritis mainly manifest as peripheral facial paralysis, such as the patient's affected side having shallower forehead wrinkles, or disappearing wrinkles, weakened eyelid closure, and in some severe cases, the inability to close the eyes, which can easily lead to corneal damage. There is also noticeable drooping of the mouth corner, a shallower nasolabial fold, and leaking while drinking. The affected individuals are unable to whistle or puff their cheeks. Some patients may also experience disorders in the secretion of salivary and lacrimal glands, taste disturbances at the anterior part of the tongue, and a few may have herpes zoster in the external auditory canal or periosteum with significant pain. The treatment for facial neuritis generally involves the use of corticosteroids.
