:856-863
 
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.

内镜鼻眼相关外科现状与展望

Transnasal endoscopic rhino-orbital related surgery: current status and future prospects

:835-842
 
鼻内镜外科技术延伸到鼻眼相关疾病的诊断和治疗已经有二十余年的历史。随着鼻眼相关解剖研究、影像诊断技术和手术器械的进步和手术临床经验的积累,大量临床和基础研究不断涌现,逐渐形成了相对成熟的内镜鼻眼相关外科理论与实践体系。本文概述了内镜鼻眼相关外科的发展现状,对几种主要手术提供经验总结并提出展望。
Nasal endoscopic surgery technology has gradually developed and involved into the diagnosis and treatment of nose-eye related disease for more than 20 years. With the improvement of anatomical studies on nose-eye, imaging diagnostic technology and surgical instruments, the accumulation of surgical clinical experience, as well as the increasing emergence of a large number of clinical and basic studies on endoscopic rhino-orbital related surgery, a well-established theoretical and practical system of endoscopic nose-eye surgery has gradually been formed. This article summarized the development of endoscopic rhino-orbital surgery, and the advantages and limitations of several major surgical methods. Also, the further research was prospected.
