Endoscopic Training Model for Intranasal Transsphenoidal Hypophysis Surgery Using a Skull Model and Chicken Wings

Abstract

AIM: To evaluate the feasibility of an experimentally designed model for training on endoscopic intranasal transsphenoidalhypophysis surgery.MATERIAL and METHODS: In this experimental study, a surgical training model for endoscopic transsphenoidal hypophysissurgery was designed to simulate real life surgical challenges, such as drilling through the sella turcica under endoscopic vision. Thislaboratory experiment was repeated at 1-week intervals and it was observed that surgeons improved their skills. The compatibilityof the training model was evaluated as either poor, acceptable or perfect.RESULTS: The results revealed that according to earlier data, greater success occurred in tests conducted after 1 week. Three newspecialist neurosurgeons also expressed that their self-confidence increased during the second procedure.CONCLUSION: This laboratory study will result in improved use of microsurgical instruments and understanding of the threedimensional surgical field, as well as the development of manual dexterity. We believe that this model will contribute to the practicaltraining of endoscopic hypophysis surgery.
