Bell Palsy - It is the most common lesion of the facial nerve. An abrupt weakness of all the facial muscles on one side, it is often accompanied by pain around the ear, unusual loudness of sounds heard in the ear on the same side, and loss of taste on the front of the tongue. Many patients believe that they have had a stroke, a conclusion corrected when it is seen that they cannot close the eye on the affected side.

Facial Hemiatrophy - (Parry-Romberg Disease) - In hemiatrophy, one-half of the skull and face may not develop as well as the other, in which case the brain also may be unusually small.

Trigeminal Neuralgia - It is a complex of symptoms of unknown cause characterized principally by brief attacks of severe pain along any of the branches of the trigeminal nerve (lying on the skull in front of the ear). The disease may occur at any age after puberty but usually begins somewhat after middle age. It affects women more frequently than men. The intense pain is usually described by patients as "stabbing," "shooting," or "lightning-like" and extremely brief. Areas around the nose and mouth become hypersensitive and, when touched, trigger an attack. Attacks are also touched off by talking, eating, drinking, or exposure to cold.
