Based on dissection and measurement on 20 adult head cadavers, there is the close relationship between lacrimal duct and lateral wall of the nasal cavity. The cells of anterior ethmoid sinus were classified into three degrees, according to the relationship between the anterior ethmoid sinus and the lacrimal sac fossa. The average distance is 6.74 +/- 1.72 mm between the nasolacrimal duct and the upper part of the uncinate process, 3.44 +/- 0.75 mm and 5.50 +/- 3.73 mm from the nasolacrimal duct to ethmoidal infundibulum and the maxillary ostium. The orifice of the duct most commonly opens under the insertion of the inferior turbinate anteriorly. To perform intranasal sinus surgery, the safest area and key operation approach were discussed.
基于对20具成人头部尸体的解剖和测量，泪道与鼻腔外侧壁之间存在密切关系。根据前筛窦与泪囊窝的关系，将前筛窦细胞分为三度。鼻泪管与钩突上部之间的平均距离为6.74±1.72mm，鼻泪管至筛漏斗和上颌窦口的距离分别为3.44±0.75mm和5.50±3.73mm。鼻泪管开口最常见于下鼻甲前部附着处下方。文中讨论了进行鼻内鼻窦手术时最安全的区域和关键手术入路。
