Abstract:
Objective To investigate the influence of the radical resection and the optic canal unroofing on the postoperative vision in the patients with tuberculm region meningeal tumors.Matheods A retrospective analysis was made in 44 patients with tuberculm region meningeal tumors,from January 2010 to October 2012.The clinical data including the Simpson grades,adhesion between tumor and the surrounding structures,optic canal decompression,and postoperative vision were studied,and followed-up.Results In all 44 cases,there were 31 patients with Simpson grade Ⅰ resection,their postoperative vision of 17 patients were improved,eleven unchanged,and 3 worse.Out of them,tumors showed more adhesive in 9 cases,unroofed the optic canal in 17 cases.There were 13 cases in the other group including 8 cases with Simpson grade Ⅱ and 5 cases with Simpson grade Ⅲ,their postoperative vision of 8 patients were improved,four unchanged,and 1 worse.Out of them,tumors showed more adhesive to the surroundings in 10 cases,unroofed the optic canal in 3 cases.There were no different postoperative vision among the Simpson grades by the Chi-Square test (P ＞ 0.05).The less adhesive of the meningeal tumors,the better resection grade would be (P ＜ 0.05).And unroofed the optic canal group showed better postoperative vision than the not unroofed ones (P ＜ 0.05).Conclusion In the tuberculum region meningeal tumors,the Simpson resection grade was related to adhesion between the meningeal tumors and the surroundings,not to postoperative vision.The optic canal decompression can improve their visual outcome in some cases.
