ABSTRACT
Objective To investigate the clinical factors which improved the postoperative vision in patients with meningeal tumor of sellar region invaded the optic canal. Methods Clinical data was collected from medical records of patient with meningeal tumors invaded optic canal from Jan. 2010 to Oct. 2016.A multiple factor analysis with logistic regression method was used to analyze these data. Results There were 55 cases included in the study. Vision was improved in 26 cases including 15 of 17 cases with early epidual optic canal decompression, 5 of 9 cases with Later optic canal decompression and 6 of 29 cases with curettage of optic canal tumor. A univariate analysis showed that resection grade,tumor adhesion and early epidural optic canal decompression were associated with visual improvement. Regression analysis showed that early epidural optic canal decompression was the only factor which could improve postoperative vision. Conclusion Early epidural optic canal decompression should be a good choice to improve the postoperative vision of meningeal tumors of sellar region invaded the optic canal.
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.
