The objective was to identify the actual benefits and persisting problems in management of vestibular schwannomas by the suboccipital retrosigmoid approach. The results and complications in a consecutive series of 120 tumours surgically treated were analysed and compared with experience involving other treatment modalities.
Pre-and postoperative clinical statuses were determined, radiological and surgical findings were collected and evaluated a database for 120 patients undergoing 125 vestibular schwannoma operations.
By the suboccipital retrosigmoid approach, 109 tumours were completely removed; in 16 cases, deliberate partial removal was performed either in severely ill patients for decompression of the brain stem or in an attempt to preserve hearing in the last hearing ear. Surgical complications included hematomas in 2.2% of the cases, cerebrospinal fluid fistulas in 9.2%, hydrocephalus in 2.3%, bacterial meningitis in 1.2%, and wound revisions in 1.1 %. The current treatment options of complete tumour resection with ongoing reduction morbidity are well fulfilled by the suboccipital retrosigmoid approach
