内镜下扩大经鼻入路海绵窦区解剖学观察

Anatomy of the extended endoscopic endonasal transsphenoidal approach to the cavernous sinus

目的通过内镜下扩大经鼻入路海绵窦解剖研究,进一步明确海绵窦内神经血管关系,为海绵窦区疾病的临床治疗提供解剖学依据。方法在8具成人尸头(共16侧海绵窦)上应用0度和30度柱状硬性内窥镜,模拟扩大经鼻入路进行海绵窦区解剖研究。结果内镜下扩大经鼻入路可清楚的显露海绵窦内结构;相关解剖标志有利于解剖定位。结论神经内镜下扩大经鼻入路是海绵窦区解剖及手术的最佳入路。

Objective To explore the endoscopic endonasal approach to cavernous sinus via extended transsphenoidal approach and establish the anatomic basis for endoscopic endonasal treatment. Methods Eight fresh adult cadavers were studied bilaterally （n = 16）. Zero and 30 degree rod lens rigid endoscope was used during dissection. After cadaver preparation, extended endoscopic endonasal approaches were performed to access the cavernous sinus. Results Endoscopic expanded nasal approach revealed the cavernous sinus structure and relevant anatomic landmarks were good for the anatomical localization. Conclusion The extended endoscopic endonasal transsphenoidal approach is the best surgical approach to the cavernous sinus.
