目的 探讨颅底良性肿瘤的ＳＲＳ治疗效果。方法 １９９４ 年７ 月至１９９６ 年１２ 月对２２例（２３ 个肿瘤） 手术后残存或者复发的颅底良性肿瘤实施了ＳＲＳ治疗。结果 治疗后大多数病人（１８２２） 的临床症状获得改善，无治疗相关的永久性颅神经损伤发生。影像学观察提示有９ 个肿瘤体积缩小，１３ 个肿瘤体积无变化，１ 例肿瘤增大。有８１３ 例（６１－５ ％ ） 神经鞘瘤病变中心表现出ＣＴ影像的低密度。结论 对经过选择的颅底良性肿瘤实施ＳＲＳ治疗，可以获得良好的局部肿瘤控制效果和比较低的治疗并发症。
Objective To investigate the therapeutic effect of SRS on skull base benign tumors. Methods From July 1994 to December 1996, SRS was performed on 22 cases of benign tumors of skull base (23 tumors) remaining or recurred after operation. Results After treatment, the clinical symptoms of most patients (1822) were improved and no treatment-related permanent cranial nerve injury occurred. Imaging findings suggest that 9 tumors shrink in size, 13 have no change in tumor volume, and 1 have increased tumors. 8 of 13 (61-5%) schwannomatosis lesions showed low density of CT images. Conclusion SRS treatment of selected skull base benign tumors can achieve good local tumor control effect and lower therapeutic complications.
