Lip-support prosthesis--a unique approach in management of bilateral facial palsy.

Facial palsy is a relatively uncommon condition with a variety of proposed etiologic factors. Commonly it affects the nerve unilaterally; bilateral involvement is very rare, accounting for less than 1% of cases. This article presents a case of bilateral idiopathic Bell palsy in a patient who had a hanging lower lip. A prosthetic appliance anchored to the teeth was fabricated to maintain the lip in its normal position, thereby helping the patient to perform normal functions.
