Bell's palsy in Moebius syndrome.

ABSTRACT

We report a case of unilateral transient and reversible facial paresis, which was superimposed on a congenital bifacial palsy in a young adult with Moebius syndrome. Our case illustrates the potential for two conditions, both affecting the facial nerve and both of unknown etiology, to be juxtaposed in a single individual. Worsening of facial palsy in the Moebius syndrome may not signify progressive disease.
