Objective To improve the degree of resection of meningioma in petroclival area and its effect after operation. Methods The clinical data of 22 cases of petroclival meningiomas were retrospectively analyzed. Results All the cases were totally resected by tumor in 12 cases, subtotal resection in 6 cases and subtotal resection in 4 cases. Of the 11 cases treated by anterior sigmoid sinus surgery, 8 cases were resected by complete tumor resection Total tumor resection in 2 cases, most of the tumor resection in 1 case. Conclusion The lithotripsy meningioma should be treated by active surgery. The anterior approach of the sigmoid sinus is the best approach for surgical treatment of petroclival meningioma. To master the surgical methods and precautions, it is helpful to improve the degree of tumor resection and operation After treatment; tumor size, texture and its relationship with the adjacent structure, but also affect the petroclival meningioma patients after the operation of an important factor.
