Abstract: Objective To investigate and evaluate the technique of microsurgery,for the treatment of the large and huge meningiomas of the sphenoid wing. Methods Fifty-eight patients were finally diagnosed by CT and/or MR in this series. The sphenoid wing meningiomas were from 4 cm×3.5 cm×3.5 cm to 11 cm×10 cm×8 cm in volume,and were located at outside sphenoid wing in 28 and at the inner in 30,and were spherical in 53 and en plaque in 5.The microsurgery for resection of the tumors was done through a cranio-orbito-zygomatic or craniozygomatic approach in 10, and through a modified pterional approach in 48.Results Total resection was achieved in 52.No death occurred in the group.Follow-up of 6 months to 9.5 years showed obvious nervous function impmvement in 49 and regrowth of the tumor in 8. Conclusions Based on the volume and development of the tumor,it is very imprtant for improving merapeutic Outcome to choose appropriate operative approach, get rid of the tumor piece by piece,and protect the nerves and vessels intraoperatively.
