OBJECTIVE: To evaluate @entity5 control and complications associated with low-dose radiosurgery for @entity5513 . METHODS: Between December 1993 and January 2000, 47 @entity1 with @entity5513 were treated at our center with gamma knife radiosurgery. The marginal @entity5 doses ranged from 7.5 to 14.0 Gy (median, 12.0 Gy) for @entity1 treated after microsurgery and from 10.0 to 15.0 Gy (median, 12.0 Gy) for @entity1 in whom radiosurgery was the primary treatment. The median maximum @entity5 diameter was 18 mm (range, 3-50 mm). Evaluation included audiometry, neurological examination, and serial imaging tests. A survey was conducted at the time of analysis. RESULTS: Follow-up data were available for 45 @entity1 and ranged from 1 to 7 years (median, 3.6 yr). In 43 @entity1 (96%), @entity5 control (no radiographic progression or surgical resection) was observed. All 33 previously untreated @entity1 had @entity5 control. Transient @entity425 , experienced in two @entity1 (4%), had resolved completely within 6 months. No @entity1 developed @entity16 . Hearing was diminished from baseline in 12% of @entity1 with useful hearing (Gardner-Robertson Class III). However, all @entity1 with pretreatment hearing Gardner-Robertson Class I or II maintained testable hearing (Class I to III) at the most recent examination. CONCLUSION: Low-dose radiosurgery in this series provided comparable local control and decreased incidences of complications in relation to other reports. Additional follow-up will allow more definitive conclusions to be reached regarding the ultimate rates of @entity5 control and hearing preservation. Nevertheless, the current dose used for @entity5513 at the University of Maryland Medical Center is 12.0 Gy to the @entity5 periphery.
