Training in endoscopic endonasal transsphenoidal surgery using a skull model and eggs

Area of Science:

• Neurosurgery
• Surgical Education

Background:

• Endoscopic pituitary surgery is a specialized technique with outcomes comparable to microscopic approaches.
• Sophisticated surgical skills are essential for successful endoscopic pituitary surgery.
• There is a need for effective training models for this advanced procedure.

Purpose of the Study:

• To develop and evaluate a novel training model for endoscopic endonasal transsphenoidal surgery.
• To provide a realistic and accessible simulation for surgical trainees.

Main Methods:

• A training model was created using a skull model with a hollowed sella turcica containing an egg.
• The egg's base simulated the sella floor, and its contents represented a tumor.
• Training utilized actual surgical instruments in an operating room setting.

Main Results:

• The model demonstrated high realism and was deemed acceptable for surgical simulation.
• Repeated practice enhanced familiarity with endoscopic visualization and technical skills like drilling and curetting.
• Using eggs with varying consistencies (raw to boiled) allowed simulation of diverse tumor types.

Conclusions:

• The developed training model effectively improves surgical techniques for endoscopic endonasal transsphenoidal surgery.
• This egg-and-skull model offers a valuable tool for surgical skill acquisition in pituitary surgery.
