The surgical aspects of 64 consecutive cases of cerebellopontine angle tumours treated from January 1983 to December 1988 are reviewed. Nearly all the procedures were done through a small suboccipital craniectomy. Two patients underwent a combined subtemporal-suboccipital approach. A stage-operation was performed on three patients harbouring a large to giant-size acoustic neuroma. The most common sign was loss of corneal reflex (29%). Hearing loss was present in 33 patients (51%). Trigeminal neuralgia occurred in 13 patients (20%) on the affected side. Hemifacial spasm was present in one patient with a 2-cm meningioma. The tumor pathology comprised of 37 acoustic neuromas, 16 meningiomas, 5 epidermoid cysts, 3 trigeminal neuromas, 1 metastatic adenocarcinoma, 1 facial neuroma, and 1 tuberculoma. Anatomic continuity of the facial nerve was preserved in 40 patients (66%). Operative mortality rate in this series was three (4.7%). None of the patients has had other further significant neurological deficits postoperatively. Most of our patients were in good condition after the operative procedures.
