Abstract:
A 7-year-old boy was referred because of a sudden change to nasal speech, dysarthria for words with explosive consonants in speech, and nasal regurgitation of fluids. The symptoms arose over 1 week following a capricious episode of acute asthmatic bronchitis. Physical and neurologic examinations were normal except for a left deviation of the uvula, accompanied by a "curtain" movement of the posterior pharyngeal wall against the opposite side, and a left deviation of the protruded tongue. No vascular, traumatic, infectious, neoplastic, or neurologic causes could be identified. No therapy was administered. Full recovery occurred 4 months later. The diagnosis was idiopathic vagal and right hypoglossal nerve palsy (Bell's palsy).
