Abstract:
Objective The aim of our study was to establish an endoscopic endonasal transsphenoidal surgical training model, and to examine its application value. Methods The endoscopic endonasal transsphenoidal surgical training models were made.After assessments,the models was used for endoscopic operation training for 8 neurosurgeons with no experiences of endoscopic operation. Results The available operating space of this model is similar to the actual operating space in endoscopic endonasal transsphenoidal surgery. The egg fixed on the model has many layers of structure, such as eggshell, shell membrane, egg white and egg yolk, which constituted a good practice object. All students indicated that they could benefit from the training using this model. The skill in grinding the eggshell [(1.07 ± 0.221)cm2/min vs.(1.45±0.27)cm2/min, P<0.001]was significantly improved and the chance for shell membrane rupture (8 vs. 2, P=0.007) was significantly reduced in the last-time practice compared with the first-time practice (P<0.001). Conclusion The endoscopic endonasal transsphenoidal surgical training model is helpful for neurosurgeons to practice the basic operation of endoscopic surgery and to improve their surgical skills,and can be used repeatedly.It can be used in basic operation training before the training using cadaver cranium.
