Objective To investigate the surgical techniques, therapeutic efficacy, and indications of retrosigmoid intradural suprameatal approach for resection of petroclival meningiomas.Methods A retrospective analysis was performed on the clinical features, surgical techniques, and postoperative complications of 15 cases of petroclival meningioma who were operated on through retrosigmoid intradural suprameatal approach from May 2016 to March 2019 via telephone follow-up.Results Before operation, all patients suffered from headache, 5 cases suffered from facial hypesthesia, 2 cases suffered from facial pain, and 1 case suffered from hearing loss. Simpson grade Ⅱ resection was achieved in 11 cases, grade Ⅲ resection in 3 cases, and grade IV resection in 1 case. During the mean followed-up period of 15 months, no one died, and the postoperative KPS scores ranged from 80 to 90. After operation, headache was alleviated in all cases; facial hypesthesia was alleviated in 3 cases, was aggravated in 2 cases, and developed in 2 cases; facial pain was alleviated in 2 cases; hearing loss remained in 1 case; diplopia developed in 2 cases, but it was alleviated 6 months later in both cases.Conclusions By grasping the indications, the retrosigmoid intradural suprameatal approach is an effective method for the resection of petroclival meningiomas.
