目的：研究日本人筛前孔（AEF）、内眦腱（MCT）和泪囊窝（LF）的解剖关系。方法：对19具日本尸体（男7例，女12例，平均死亡年龄89.3岁）的38个眼眶进行了实验性解剖学研究。暴露AEF、MCT和LF的上级边界。测量AEF正前方眶内侧缘点至MCT上级缘的距离（AEF-MCT）和LF上级缘至MCT上级缘的距离（LF-MCT）。结论：经皮筛前神经阻滞可在不损伤泪囊的情况下进行，在距筛前神经上缘约9mm处进针，可有效地阻滞筛前神经。
Purpose:To examine the anatomical relationships of the anterior ethmoidal foramen (AEF), medial canthal tendon (MCT), and lacrimal fossa (LF) in Japanese individuals.Methods:Thirty-eight orbits from 19 Japanese cadavers (7 men and 12 women; average age at death, 89.3 years) were used in this experimental anatomical study. The AEF, MCT, and superior border of the LF were exposed. The following distances were then measured: 1) from the point at the medial orbital rim directly anterior to the AEF to the superior border of the MCT (AEF-MCT), and 2) from the superior border of the LF to the superior border of the MCT (LF-MCT).Results:(AEF-MCT) and (LF-MCT) distances were 9.40±1.92 (mean±standard deviation) and 4.21±1.18 mm, respectively. No values of (LF-MCT) exceeded the mean (AEF-MCT)(9.40 mm).Conclusions:The transcutaneous anterior ethmoidal nerve block can be reliably performed without injury to the lacrimal sac by inserting a needle approximately 9 mm superior to the superior border of the MCT.
