OBJECTIVES: 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. MATERIALS AND METHODS: Dacryocystography was performed on lamb's head models, which were then meticulously dissected, both macroscopically and endoscopically, to assess the nasolacrimal system. RESULTS: Dacryocystography showed the absence of a lacrimal sac in all the lamb's heads dissected. This result was confirmed by dissection. CONCLUSION: 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.
