What Is Bell's Palsy?
Reviewed: Dr. Gromatzky
5. Complications
In most instances, patients experience an episode of Bell’s palsy with no further complications and usually have a full recovery. Problems occur when the condition is severe. The complications include severe damage of the facial nerve, leading to loss of most or all functions on one side of the face.
Due to the severe decrease in the production of tears, the eyes become excessively dry. Dry eyes are exposed to eye infections, ulcers, and blindness if the condition persists without treatment. Another complication of Bell’s palsy is synkinesis. This is involuntary movement of one part of the body when the patient moves another part. For example, when the patient smiles, the eyes close involuntarily.
