| 摘 要： | 目的 :明确泪囊窝的解剖学特点 ,为鼻内镜下鼻腔泪囊造孔术提供参考。方法 :对 2 3具 (4 6侧 )成人尸头泪囊窝的骨性结构构成及骨壁的厚度和倾斜角度进行测量。结果 :泪囊窝中部的骨性构成中上颌骨额突所占比例略大于泪骨 ,且变异较大 ;泪囊窝后壁与冠状面呈大约 2 0°的倾角。结论 :在鼻内镜鼻腔泪囊造孔术中 ,应对眶壁行CT检查 ,以明确不同类型泪囊窝骨性构成情况下手术可能遇到的问题 ,防止术中眶内并发症或由于造孔过小导致术后鼻泪管阻塞 ,症状不能缓解

| Abstract: | OBJECTIVE: To explore the characteristic of lacrimal sac fossa on ESS and traditional maxillary operation, and to provide anatomy basis for the endoscopic endonasal dacryocystorhinostomy. METHOD: Twenty-three heads of adult cadaver specimens were examined including the shape, direction and the thickness of wall of lacrimal sac fossa. RESULT: The fossa is formed by the frontal portion of the maxillary bone and the lacrimal bone. The proportion of the frontal portion of the maxillary bone is bigger than the lacrimal bone. There is about 20 degrees between the rear wall of the fossa and the coronal plane. CONCLUSION: Before the endoscopic endonasal dacryocystorhinostomy we should scan the anterior portion of the medial orbital wall so that we can understand the anatomy of the fossa and improve the effect of the surgery. |
