Efficacy of Concomitant Intratympanic XXXX Injection for Sudden Deafness According to Initial @entity393 .

@entity1 @entity1274 @entity230 @entity393 @entity479
OBJECTIVES/HYPOTHESIS: We identified the efficacy and appropriate target group for intratympanic @entity479 injections (ITS) in @entity1 with @entity1274 ( @entity1274 ). STUDY DESIGN: Retrospective case-control study. METHODS: Fifty-five ears treated with concomitant ITS and systemic @entity230 and 165 ears without ITS treatment were identified. Each case had three controls matched according to the age, sex, and the presence of vertigo. @entity1 were divided into subgroups according to pure tone audiometric configuration and the levels of initial @entity393 . Hearing results and frequency-related @entity393 were investigated. RESULTS: Additional ITS was effective for @entity1 with an ascending type audiogram or @entity1 with Grade 3 (60-90dB) initial @entity393 . Concomitant ITS, however, resulted in a negative effect on hearing in @entity1 with Grades 1 and 2 (<60dB). ITS resulted in significant (p<0.05) hearing improvement at 250Hz in the Grade 3 (60-90dB) and Grade 4 (>90dB) ITS subgroups. CONCLUSIONS: The efficacy of additional ITS for @entity1274 was different among subgroups with various levels of initial @entity393 or audiogram configuration.
