Background: Evaluation of the outcome of microsurgical removal of vestibular schwannoma via retrosigmoid approach. Materials &Methods: 50 patients with presence of unilateral VSs were enrolled in the present study. Evaluation of facial nerve function was done immediately after surgery and during follow-up. Facial nerve function was categorised as good, fair and poor. Evaluation of the hearing function was done by audiology examinations including pure tone audiometry (PTA) and speech discrimination score (SDS). All the patients were managed by sub-occipital retrosigmoid approach. Following the surgical treatment, MRI evaluation of all the patients was done. Postoperative complications were evaluated. All the results were recorded and analysed using SPSS software. Results: Gross total resection was done in 90 percent of the patients while near total resection was done in 8 percent of the patients. Partial resection was done only in 1 patient. Electrophysiological monitoring during surgery was done in 92 percent of the patients while external ventricular drainage was done in 4 percent of the patients. Overall mortality was seen in 1 patient (2 percent). Deafness, facial paralysis, tinnitus, disequilibrium and facial paralysis was seen in 30 percent, 42 percent, 40 percent, 32 percent and 22 percent of the patients respectively. Conclusion: A nicely planned surgery with the help of microsurgical techniques for managing vestibular schwannoma patients helps in achieving good functional outcome and tumor control.
