Although @entity394 ( @entity394 ) are relatively rare as compared to other @entity5 , growing attention is required to achieve better outcomes with less morbidities among @entity1 . In this retrospective study, we compared functional outcomes of retrosigmoid approach microsurgery (RSAMS) and gamma knife stereotactic radiosurgery (GKSRS) in @entity394 @entity1 with serviceable hearing. Forty-six @entity1 in inclusion criteria, who underwent RSAMS (n = 15) or GKSRS (n = 31) between January 2004 and June 2009 were reviewed. We evaluated symptoms at initial presentation, pre- and posttreatment pure-tone audiometry, speech discrimination score, @entity5 size, pre- and posttreatment assessments of facial nerve function, and pre- and posttreatment tinnitus, @entity1296 and @entity809 in @entity5513 @entity1 , who were treated with RSAMS or GKSRS. Hearing disturbance was the most common presenting symptom in both the groups. The hearing preservation rates in the RSAMS and GKSRS @entity1 were 7% (1/15) and 45% (14/31), respectively. Two RSAMS @entity1 and one GKSRS @entity1 developed new @entity16 , defined as a temporary or permanent decline in House-Brackmann facial nerve grade. @entity5 recurrence was observed in one RSAMS @entity1 , whereas @entity5 size increase was observed in one GKSRS @entity1 (3%). Tinnitus score was decreased after the treatment in both the groups. The results imply that GKSRS for @entity5513 can possibly preserve hearing preservation with proper indication and treatment planning.
