Structured training in endoscopic sinus surgery is essential, considering the serious potential complications. We have developed a detailed endoscopic endonasal surgery training programme, using a lamb's head model. This study aimed to assess the possibilities of using such a model for endoscopic dacryocystorhinostomy training.
Dacryocystography was performed on lamb's head models, which were then meticulously dissected, both macroscopically and endoscopically, to assess the nasolacrimal system.
Dacryocystography showed the absence of a lacrimal sac in all the lamb's heads dissected. This result was confirmed by dissection.
Lamb's heads are excellent models with which to teach endoscopic sinus surgery techniques. However, this study clearly demonstrated the absence of a lacrimal sac in all such models dissected. Thus, this animal model is inappropriate for endoscopic dacryocystorhinostomy training.
考虑到内镜鼻窦手术存在严重的潜在并发症，结构化培训至关重要。我们利用羊头模型制定了详细的鼻内镜手术培训方案。本研究旨在评估使用该模型进行内镜下泪囊鼻腔造口术培训的可能性。
对羊头模型进行泪囊造影，然后进行细致的宏观和内镜解剖，以评估鼻泪系统。
泪囊造影显示，所有解剖的羊头均无泪囊。解剖结果证实了这一结果。
羊头是教授内镜鼻窦手术技术的优秀模型。然而，本研究清楚地表明，所有解剖的此类模型均无泪囊。因此，这种动物模型不适用于内镜下泪囊鼻腔造口术培训。
