摘要
目的:探讨泪骨在泪囊鼻腔吻合术中的重要意义。方法:测量10具(男5具,女5具)成人尸头鼻腔外侧壁上泪骨的长、宽、厚,观察钩突、上颌线和M点(上颌线的中点)的解剖位置。结果:泪骨在鼻腔外侧壁位于钩突的前方,骨质菲薄,所测量的长、宽、厚的平均值分别为9.23、3.63和0.06 mm。结论:使用咬钳可以咬除泪骨,进一步开放泪囊内壁骨质,同时避免使用电钻,减小创伤。钩突、上颌线及M点可作为术中可靠的定位标志。
Objective： To explore the significance of the lacrimal bone at the lateral nasal wall in endoscopic dacryocystorhinostomy. Method：The position, dimension and thickness of the exposed lacrimal bone at the lateral nasal wall in 10 cadaveric heads（male 5, female 5） were examined and the anatomy of uncinate process, the maxillary line and M point were studied, too. Result： The lacrimal bone at the lateral nasal wall is always situated immediately anterior to the uncinate process. The average length and width of the lacrimal bone was 9.23 mm and 3.63 ram, respectively. The lacrimal bone was very thin with an average thickness of 0.06 mm. Conclusion： The study indicates that the lacrimal bone is so thin that a bony rongeur is usually sufficient to nibble it away. The medial wall of the sac is then removed without the use of drill or chisel with less operative trauma. The uncinate process, the maxillary line and M point are reliable landmarks in endoscopic dacryocystorhinostomy.
