OBJECTIVE: To review the natural course of @entity5 size and hearing during conservative management of 151 @entity1 with unilateral @entity5513 ( @entity5513 ), and to evaluate the same parameters for the part of the group (n = 84) who were treated by LINAC stereotactic radiosurgery (SRS). METHODS: In prospectively collected data, @entity1 underwent MRI and complete audiovestibular tests at inclusion, during the conservative management period and after SRS. Hearing was graded according to the @entity4511 and @entity5 size according to Koos. Statistics were performed using Kaplan-Meier survival analysis and multivariate analyses including linear and logistic regression. Specific insight was given to @entity1 with serviceable hearing. RESULTS: During the conservative management period (mean follow-up time: 24 months, range: 6-96), the annual risk of GR class degradation was 6% for GRI and 15% for GR II @entity1 . @entity393 as an initial symptom was highly predictive of further @entity393 (p = 0.003). @entity5 growth reached 25%. For SRS @entity1 , functional hearing preservation was 51% at 1 year and 36% at 3 years. @entity5 control was 94 and 91%, respectively. CONCLUSION: In @entity5513 @entity1 , @entity393 at the time of diagnosis is a predictor of poorer hearing outcome. LINAC SRS is efficient for @entity5 control. @entity1 who preserved their pretreatment hearing presented @entity393 per year after SRS than before treatment, suggesting a protective effect of SRS when cochlear function can be preserved.
