摘　　要：目的探讨内镜下经鼻咽入路显露和切除齿状突的可行性。方法选取新鲜成人尸头湿标本4具,椎动脉、颈内动脉内灌注红色乳胶,颈内静脉灌注蓝色乳胶,防腐剂阴冷处保存。在尸头标本上模拟内镜下经右侧鼻孔入路切除齿状突。结果标本在内镜下术野暴露均满意,切开咽后壁、肌肉及筋膜韧带后,向上可以暴露下斜坡,向下可以暴露寰枢椎,磨除寰椎前弓后可以成功切除齿状突。结论内镜下经鼻入路可以作为前路齿状突切除的选择之一。Objective To explore the feasibility ofexposuring and resecting the odontoid process via endoscopic endonasal approach （EEA）. Methods Four flesh cadaver heads were used in this study. The vertebral arteries and internal carotid arteries were injected with red latex, and the internal jugular veins with blue latex. The odontoid process was resected through right nostril using an endoscopy simulator. Results EEA provided a nice exposure of the lower clivus, atlas and axis. Odontoidectomy was done successfully via EEA on all the four specimens. Conclusion EEA is a valid alternative for anterior odontoidectomy.
