Meningiomas of the cerebellopontine angle. A report of 41 cases.
A retrospective study of the surgical management of 41 cerebellopontine angle (CPA) meningiomas was performed. All patients were treated by a single surgeon (TTK) over a 25 year period (1967-1992). There were 13 males, 28 females with a median age of 53.5 years. The median follow-up after surgery was 9 years (range 2-20.4 years). Tumours were classified anatomically into six groups (lateral, midpetrosal, petroclival, internal auditory meatal, Meckel's cave and inferior). Only the petroclival tumours posed difficulties with complete resection (achieved in 7 out of 16) and for most of them a transtentorial transpetrous approach was used. In other groups, complete resection was achieved in all patients. There were four recurrences (two mid-petrosal, one petroclival, one internal auditory meatal), three of which had complete macroscopic resection at the initial operation.
