目的 :寻求理想的结扎筛前动脉的手术入路。方法 :以 12具湿性尸头和 2 0具干尸头标本为解剖材料 ,实地测量并以额筛缝为标志改良手术进路。将观察结果用于临床 ,治疗难治性鼻出血。结果 :筛前孔及筛前动脉距眶缘约 2cm ,改良手术入路并应用显微手术术野清晰 ,可操作性强 ,临床效果好。结论 :改良筛前动脉结扎术简单、实用、有效 Objective: To seek the ideal surgical approach of ligating the anterior ethmoid artery. Methods: 12 wet corpse and 20 corpse head specimens were used as anatomical materials, and the surgical approach was improved on the spot and screened by the frontal seam. The observation results for clinical use, treatment of intractable epistaxis. Results: The anterior ethmoidal mesh and anterior ethmoid artery were about 2 cm away from the orbital rim. The improved operative approach and the microsurgical operative field were clear and operable. The clinical effect was good. Conclusion: Improved anterior ethmoidal ligation is simple, practical and effective
