Objective To study the methods and techniques of the treatment forextensive suprasellar pituitary adenona and repairing hole.Methods From Feb. 2001 to Mar. 2003, 9 patients with exrensive suporasellar pituitary adenoma underwent resection via suprabital keyhole with endoscope-assisted microneurosurgery. Then the remaining tumor was removed with neuroendoscope via Ⅰand Ⅱ space of optic chiasma. The small bone flap was fixed with Ti clamp. Results After the tumor was removed with microneurosurgery, the remaining tumor was still found with endoscope in 7 cases. Remaining tumor was totally removed in 6 cases, almost removed in 3 cases. The vision improvement was found in 7 cases one week after surgery. In the other 2 cases, the vision remained unchanged. Follow-up was conducted in 6 cases for 6 to 22 months. Neuroradiological recovery of MRI with no recurrence of tumor was observed. No complication of incision was present. Conclusion Enough intra and extra-cranial space can be provided to operate via orbital roof approach to sellar tumors. Endoscope-assisted microneurosurgery can increase the total-resection and successful rate treatment for extensive suprasellar pituitary adenoma, reduce the possibility of complication, and pretect the function of brain from being injured. Fixation of small bone flap with Ti clamp is safe, easy and reliable.
