Abstract：Objective To investigate the choice of operative approach of petroclival meningiomas and the curative effect of microsurgery on them. Methods The clinical data of 23 patients with petroclival meningioma who underwent microsurgery from November 2014 to November 2015 were analyzed retrospectively. Of 23 patients, 15 patients were treated via subtemporal transatentorial approach and 8 via suboccipital retrosigmoid approach. Results Total resection of the tumor was achieved in 17 patients and partial resection in 6. Postopetive pulmonary infection occurred in 1 patient, oculomotor paralysis and facial paralysis in 3, and temporal lobe edema with hemorrhage in 2. The following-up ranging from 6 to 18 months (median, 13 months) showed that there was no recurrence and no progression of the residual tumors. The KPS score at the last follow-up was significantly higher than that before the operation (P<0. 05). Conclusions The comprehensive treatment of petroclival meningioma should be individualized, operation-centered, combined with radiotherapy and chemotherapy, and should be guided by patients'quality of life. The ultimate goal is to improve the survival rate of patients and ensure the quality of life at the same time.
