Treatment of facial palsies resulting from surgical conditions and trauma, and current information on spontaneous (Bell's) facial paralysis are among the contributions from the International Symposium on the Management of Facial Paralysis, which are presented in the May Archives of Otolaryngology.
Spontaneous facial paralysis is a disorder of unknown etiology which, though predominant in adults, may afflict either sex at any age. The clinical picture is stereotyped and diagnosis is usually easy. About three of every five patients recover completely, having suffered conduction block only. The remainder undergo varying degrees of denervation of the facial muscles. Although all these patients eventually recover voluntary movement and eye closure, some degree of "associated movement" and defective function always develops after denervation. About 10% of the patients are permanently disfigured.
The likelihood of denervation increases with age, but until recently the prognosis could not be decided accurately in the early stages. Now, however,
