FEASIBILITY AND EFFECTIVENESS OF RETROSIGMOID APPROACH IN VESTIBULAR SCHWANNOMA SURGERY

FEASIBILITY AND EFFECTIVENESS OF RETROSIGMOID APPROACH IN VESTIBULAR SCHWANNOMA SURGERYPurpose: To assess the feasibility and effectiveness of lateral suboccipital retrosigmoid approach in surgical management vestibular schwannoma.Materials Methods: We conducted a prospective hospital-based case series on 356 patients during period from May 2018 to 2020 collaboration with neurosurgery department, Sohag University hospital, Tokyo Medical Hospital. Patients included who were undergoing intervention for schwannoma (VS) through approach. All our study followed up minimum four months. For each patient intraoperative tumor resection volume was recorded, postoperative complications, facial cochlear nerve functions assessed.Results: Enrolled this cases, majority (54.8%) females; while (45.2%) males mean age (42.57 ± 12.3) years. achieved follow-up 6.2 months; ranging (4-9 months). Postoperative scoring function good outcome 79.4%, fair 17.5%, poor 3.1%.Conclusion: assessed results surgery using VS. Surgical VS is safe effective but after advancement microsurgical techniques like drilling neurophysiological monitoring especially seventh eighth cranial nerves, possibility preserving became more feasible excellent results.
