Multiple approaches for the cerebello-pontine angles have been developed to permit the surgeon to tailor the procedure to a particular patient's pathology and physiological status. Each has its own limitations, morbidities, and indications. Among them, the retrosigmoid approach provides simple and direct access to the cerebello-pontine zone.


A retrospective study was performed on 35 consecutive patients with a vestibular schwannoma who underwent retrosigmoid surgery.

The patients consisted of 12 men and 23 women, of meanstandard deviation (SD) age 52.510.4 years (range, 35-75 years). The lesion sides were 19 cases in right and 16 cases in left. The symptoms for vestibular schwannoma patients included hearing disturbance (31 cases, 89%), tinnitus (14 cases, 40%), headache (12 cases, 34%), vertigo (11 cases, 31%), and facial palsy (2 cases, 6%).
