Sudden neurosensorial deafness in Bell’s Palsy

Summary

Three cases of sudden neurosensorial deafness in Bell’s Palsy have been presented. In the first case the deafness and the facial palsy were on contralateral sides. There were no signs of disturbances of sense of taste or lacrymation in any of them. We are of the opinion that this combination is suggestive of the existence of a common factor playing a major role in the pathogenesis of these conditions and as the local vascular disturbance is generally regarded as the chief mechanism, involved in Bell’s Palsy, probably a similar spasmodic lesion in the labyrinthine vessels might be responsible for sudden deafness.
