Facial Palsy

Facial palsy can be related to an acute viral infection (Bell’s palsy) or follow surgery of an acoustic neurinoma. Most often the recovery is good. However, if the recovery is incomplete, there is an asymmetry of the face, in particular when the patient is smiling, watery eyes with tears occurring during meals (crocodile tears). Pulling of the corner of the mouth when blinking, and vice-versa (eye closure when speaking or smiling, synkinesias) give the appearance of a winking eye and cause much social embarrassment to the patient. These problems are due to aberrant (or hap-hazard) regeneration of the facial nerve, and can be helped with Botulinum toxin injections.
