目的探讨经眶上缘外侧锁孔入路鞍区的内镜解剖及操作技术。方法本组采用15具10%甲醛溶液固定的成人尸头和1例新鲜尸头,经眶上缘外侧锁孔入路应用内镜(0°镜、30°镜)对鞍区各间隙进行解剖观察并模拟手术操作。结果经眶上缘外侧锁孔入路开颅可达到经典翼点入路对骨窗的基本要求,通过使用内镜,可清晰的显露间隙Ⅰ、Ⅱ、Ⅲ、Ⅳ,尤其对重要穿通血管的显露更明确。结论经眶上缘外侧锁孔入路创伤小,暴露好;其中间隙Ⅰ、间隙Ⅲ是鞍区内镜探查最常使用且较为安全的间隙。
Objective To investigate the endoscopic anatomy and operative technique of the supraorbital margin keyhole into the sellar region. Methods Fifteen adult cadaver heads and one fresh cadaver head fixed with 10% formaldehyde solution were used in this study. The gaps in the saddle area were dissected with endoscope (0 ° mirror, 30 ° mirror) Observe and simulate surgical procedures. The results of the supraorbital margin lateral keyhole approach craniotomy can reach the classic wing point of the basic requirements of the bone window, through the use of endoscopy, can clearly reveal the gap Ⅰ, Ⅱ, Ⅲ, Ⅳ, especially for important perforating vascular Revealed more clearly. Conclusions The traumatic approach through the lateral supraorbital margin keyhole approach is small, and the exposure is good. Among them, the gap Ⅰ and the gap Ⅲ are the most commonly used and safe gaps in the sella region endoscopy.
