Objective: To explore and evaluate the application and effect of an integrated   ocular anatomy course comprising three main components: ‘online preview,’ ‘lecture,’ and ‘Wetlab dissection training’in the standardized training teaching of ophthalmology residents (hereinafter referred to as "resident training"). Methods: A total of 93 new resident trainees from Zhongshan Ophthalmic Center of Sun Yat-sen University in 2023 were included in the integrated course on ocular anatomy during pre-job training. Tests were carried out before and after the course to evaluate the teaching effect of the course, and questionnaires were issued after the course to investigate the satisfaction of the course. It adopts the form of anonymous offline test and satisfaction questionnaire. Results: The median total scores before (T1) and after (T2) training were 60 and 70, respectively; the lowest scores, 25%, 75% and highest scores of T1 were 10, 40, 62.5 and 90, respectively; the lowest scores, 25%, 75% and highest scores of T2 were 30, 60, 80 and 100, respectively, and the scores of T2 were significantly higher than those of T1. The difference was statistically significant (P<0.000 1). The mean confidence of T1 and T2 were 26.53±5.08 and 31.83±4.02, respectively, and the difference was statistically significant (P<0.001). Participants generally expressed satisfaction with the integrated programme. Conclusions: After receiving the training of the integrated course, the students' mastery of the knowledge of ocular anatomy has been significantly improved, and the satisfaction of the integrated course is high. The integrated course on ocular anatomy is effective, and it is a teaching reform with popularization significance.

目的：通过在血管灌注尸头标本上模拟经鼻内镜下鼻泪管-泪囊切除术探讨该术式的基本操作以及在经鼻内镜下鼻泪管-泪囊和其周围结构的解剖关系，以期为临床开展该术式提供解剖学依据。方法：采用5个动、静脉双灌注成人尸头标本(共10侧)进行解剖学研究。在标本上进行经鼻内镜下暴露全程鼻泪管及泪囊，观察鼻泪管-泪囊切除过程的解剖标志和毗邻关系。结果：10侧泪囊-鼻泪管的解剖显示全部泪囊均位于鼻丘的前方稍外侧，泪囊顶基本和鼻丘顶平齐，泪囊体大部分位于中鼻甲腋窝水平线上方。泪囊窝后内壁由泪骨构成，泪骨后内方与鼻丘气房相邻。泪囊底向下移行为膜性鼻泪管进入骨性鼻泪管，鼻泪管在鼻腔外侧壁的投影位于钩突垂直部前缘前方约3~7mm。鼻泪管下鼻道开口距离下鼻甲前端的距离为(16±3)mm。泪囊长度为(13.8±1.8)mm，鼻泪管长度为(23.2±3.6)mm。结论：经鼻内镜入路可充分暴露和切除全程鼻泪管和泪囊。本解剖研究展示的基本操作过程和解剖标志可为临床开展经鼻内镜鼻泪管-泪囊切除术提供解剖学参考。

Objective: By simulating transnasal endoscopic resection of nasolacrimal duct and lacrimal sac on cadaveric specimens with vascular perfusion, the basic process of this procedure and the anatomical relationship between nasolacrimal duct and lacrimal sac were explored, providing anatomical basis for clinical application. Methods: Five adult cadaver head specimens (10 sides in total) were used for anatomical study. The nasolacrimal duct and lacrimal sac were exposed under transnasal endoscopy, and the anatomical landmarks and their relationship with adjacent areas during the resection of nasolacrimal duct and lacrimal sac were observed. Results: Ten sides of nasolacrimal duct and lacrimal sac showed that all lacrimal sacs were located anterior and slightly lateral to the nasal mound. The roof of lacrimal sac was almost the same height as the roof of nasal mound. The body of lacrimal sac was almost located above the horizontal line of the middle turbinate axilla. The posterior inner wall of the lacrimal fossa was composed of lacrimal bone. The posterior inner side of the lacrimal bone was adjacent to the agger nasi cell. The bottom of the lacrimal sac moved downward as the membranous part of the nasolacrimal duct located in the bony part of the nasolacrimal duct. The projection of the nasolacrimal duct on the lateral nasal wall was located about 3–7 mm in front of the anterior edge of the vertical part of the uncinate process. The distance between the inferior meatus opening of the nasolacrimal duct and the anterior end of the inferior turbinate was (16±3) mm. The length of the lacrimal sac was (13.8±1.8) mm, and the length of the nasolacrimal duct was (23.2±3.6) mm. Conclusion: The transnasal endoscopic approach can fully expose and resect the nasolacrimal duct and lacrimal sac. The basic operation process and anatomical landmarks demonstrated in this anatomical study provide an anatomical reference for the clinical development of transnasal endoscopic resection of nasolacrimal duct and lacrimal sac.
