Bell’s Palsy

Bell’s Palsy

Bell’s palsy is the most common cause of facial paralysis and weakness. It is thought to be due to a viral cause. Approximately 90 percent of patients regain full function in their face with appropriate medical treatment.

The approximate 10 percent of patients do not recover complete function. These patients may benefit from minor surgical procedures that improve their eye function. If you have newly diagnosed Bell’s palsy and would like an urgent evaluation, please request the first available appointment.

Some patients who have had Bell’s palsy may go on to develop synkinesis. This is a condition that causes unwanted contractions of the muscles of the face. It is essentially a “faulty re-wiring” of the facial nerve that occurs after injury and recovery. It can be surprisingly distressing to patients and may impact emotional expression and facial function severely.
