| 摘 要： | 目的探讨无框架MRI导航系统在内窥镜经蝶鞍区肿瘤切除术中的作用。方法回顾性研究8例垂体腺瘤和2例颅咽管瘤病人在无框架MRI影像导航引导下内窥镜经蝶入路垂体腺瘤切除病人的临床资料。结果机器定位误差平均1．5mm；重要结构和病变定位满意，导航注册时间平均5min；手术时间平均50min，术后所有病人症状均减轻和好转。术后短暂性脑脊液鼻漏3例，短暂性尿崩者3例，无颅内感染及出血病例。结论无框架影像导航在内窥镜经蝶鞍区肿瘤的手术治疗中使重要结构及病变定位准确，在手术中可发挥重要作用。

Frameless MRI Image-Guided endoscopic transsphenoidal removal of tumor of sellar region |
| |
| Abstract: | Objective: To assess the role that neuronavigation plays in assisting endoscopic transsphenoidal surgery for tumors of sellar region. Methods: 10 endoscopic endonasal transsphenoidal reoperations were performed for 8 patients with pituitary adenoma and 2 with craniopharyngioma. Clinical records were reviewed retrospectively. Results: The mean setup time was 5 minutes, and the operative time was 50 minutes in image-guided procedures. In all cases, the system performed without malfunction. Continuous information regarding instrument location and trajectory was provided to the surgeon. Measurements of the intraoperative accuracy in the axial, coronal, and sagittal planes indicated a mean intraoperatively verified system error of 1.5 mm. Conclusion: Neuronavigation can be applied during endonasal transsphenoidal endoscopic surgery and requires a minimal amount of time. It makes reoperation easier, faster, and probably safer. |
