Update on the ophthalmic management of facial paralysis.

Bell's palsy is the most common neurologic condition affecting the cranial nerves. Lagophthalmos, exposure keratopathy, and corneal ulceration are potential complications. In this review, we evaluate various causes of facial paralysis as well as the level 1 evidence supporting the use of a short course of oral steroids for idiopathic Bell's palsy to improve functional outcomes. Various surgical and nonsurgical techniques are also discussed for the management of residual facial dysfunction.
