Abstract:
Objective To explore clinical curative effect of microsurgery of petroclival tumors by transpetrosal presigmoid approach. Methods A series of 23 patients of petroclival tumors resected by microneurosurgery were analyzed retrospectively, including tumors histological types, clinical and preoperative MRI features, operative approaches, surgical technique and common postoperative complications. Results Total resection of the tumor was achieved microsurgically in 16 cases, subtotal resection in 4 cases, partial resection in 3 cases. No patient died in this series. 8 patients presented worsening crainal nerves palsies postoperatively. CSF leaks were uncommon, occuring in 2 patients. Conclusion The tumors in petroclival region can be totally resected by transpetrosal presigmoid approach. The advantages were offered by this approach such as the temporal lobes and cerebellum are minimally retracted; the operative distance of petroclival tumors is shortened with exposure of clivus and juxta-clival region.
