Evaluation of an anatomic model of the paranasal sinuses for endonasal surgical training

OBJECTIVES: To assess the suitability of a new anatomic model of the paranasal sinuses for endonasal surgical training. STUDY DESIGN: Prospective observational pilot study. METHODS: A new anatomic model of the paranasal sinuses was developed by the Department of Anatomy at the University of Zurich. The practicability of the model was evaluated by three experienced endoscopic sinus surgeons with a special focus on its possible use in training. Standardized surgical procedures were performed under simulated real-life conditions in the operating theatre. RESULTS: The endoscopic appearance of the nasal airway closely resembled real human tissue and the detailed anatomy of the model allowed the same structured surgical steps to be performed as in real life in the absence of bleeding. CONCLUSION: This anatomic model is a readily available teaching tool for endoscopic sinus surgeons.
