Area of Science:

Medical Simulation
Surgical Education
Otolaryngology

Background:

Assessing surgical skill acquisition is crucial for patient safety.
Virtual reality simulators offer a controlled environment for surgical training.

Purpose of the Study:

To evaluate the influence of surgical experience on technical competence.
To validate the Flinders sinus surgery simulator for differentiating expertise levels.

Main Methods:

Ten experienced surgeons and 14 novices performed three simulated endoscopic sinus surgery tasks.
Tasks involved anatomical landmark identification, tissue removal, and precise cutting using haptic controllers.

Main Results:

Novices demonstrated significantly longer task completion times across all simulations.
Novices exhibited increased instrument travel distance and greater force application.
Novices performed more cutting movements, indicating reduced efficiency compared to experts.

Conclusions:

The Flinders sinus surgery simulator effectively differentiates between novice and expert surgeons.
Simulator metrics correlate with surgical experience, validating its use in training and assessment.
