- Ageusia (chronic loss of taste): Temporary loss of taste is common in Bell's Palsy but it can also result in permanent loss of taste.
- Chronic facial spasm: The face remains in a permanent state of spasm in some people.
- Eye problems: Corneal infection may result in permanent damage to eye, ulcerations or permanent blindness.
- Persistent facial weakness: This includes continuing loss of control over facial muscles with difficulty in speech, eating and drinking.
- Synkinesis: It is a condition where when a part of body is moved it leads to simultaneous movement of other body part. For example, automatic closing of eye on smiling. It occurs mostly during nerve re growth.
