Significance of auditory brain stem response and XXXX -enhanced magnetic resonance imaging for @entity1274 .

Previous studies tried to correlate prognosis and response to oral @entity288 in @entity1 with @entity1274 to such factors as the age of the @entity1 , presence of vertigo, shape of the audiogram, or severity of the @entity393 . However, temporal bone histopathologic evidence shows that @entity1274 may be caused by cochleitis or cochlear nerve @entity5013 . Herein we report results of a retrospective study of 96 consecutive @entity1 with @entity1274 who were evaluated with auditory brain stem responses and @entity2287 -enhanced magnetic resonance imaging. Results of the auditory brain stem response and magnetic resonance imaging were correlated with hearing outcome. Follow-up was available for 65 @entity1 : 14 with abnormal and 51 with normal auditory brain stem responses. The overall rate of hearing recovery or improvement was 65% in the normal auditory brain stem response group compared with 43% in the abnormal auditory brain stem response group (p = 0.07). Among the 38 @entity1 treated with a tapering course of oral @entity288 , the recovery or improvement rate was 83% for those with normal auditory brain stem responses and 56% for those with abnormal auditory brain stem responses (p < 0.05). Of the 27 @entity1 who did not receive @entity134 therapy, the improvement rate was 41% in those with normal auditory brain stem responses and 20% in those with abnormal auditory brain stem responses (p = 0.09). Magnetic resonance imaging with @entity2287 was obtained on all 14 @entity1 with abnormal auditory brain stem responses but on none with normal auditory brain stem responses.(ABSTRACT TRUNCATED AT 250 WORDS)
