INTRODUCTION: Acoustic neuroma (AN) or vestibular schwannoma, is a benign, slow-growing tumour that arises from the Schwann cell of branch vestibulocochlear nerve. Treatment options are mainly conservative surgical excision. The aim this study to describe clinical characteristics AN and outcomes in Malaysian tertiary hospital. MATERIALS AND METHOD: Records 73 patients who were diagnosed with January 2008 until December 2019 retrieved. All analyzed for demographic data characteristics. In all 52 underwent surgery had normal preoperative facial nerve function. A descriptive analysis was used each patient. RESULTS: median age 51.5 (15.8 SD). Hearing levels pre-operatively severe profound 74.0% patients, followed by moderate 15.1%, mild 6.8%, hearing loss 2.7%. Retrosigmoid (48.1%) most common approach used, translabyrinthine (44.2%) middle cranial fossa (MCF) (7.7%). associated least incidence paresis postoperatively (21.2%) when compared retrosigmoid approaches (40.4%). However, there no significant association between outcome (p=0.07). CONCLUSION: safe procedure, regardless used. There relationship size outcome.
