Virtual reality simulators enhance understanding of sinus anatomy for endoscopic nasal surgery training. However, they did not improve operating room performance due to limitations like lack of force feedback.

Area of Science:

  • Medical Simulation
  • Surgical Education
  • Otolaryngology

Background:

  • Virtual simulation offers a promising avenue for medical and surgical training.
  • Evaluating the efficacy of a novel simulator for endoscopic nasal procedures in a structured training program.

Purpose of the Study:

  • To assess the impact of a virtual reality simulator on the training of junior residents for endoscopic nasal procedures.
  • To identify the benefits and limitations of using virtual simulation in surgical education.

Main Methods:

  • Two third-year residents simulated twenty endonasal operations for chronic rhinosinusitis using a 3D volumetric data simulator.
  • Proctored simulation sessions were conducted one day prior to actual endoscopic sinus surgery.
  • A questionnaire was administered to gather feedback on the simulator's utility and user experience.

Main Results:

  • The surgical simulator improved junior residents' understanding of paranasal sinus morphology.
  • A minor impact on the performance of endoscopy by junior residents was observed.
  • Identified disadvantages included significant time consumption and lack of force feedback.

Conclusions:

  • Virtual simulators enable surgeons without prior endoscopic nasal training to practice using real patient data.
  • The simulator did not demonstrate a significant impact on actual operating room performance.
  • Limitations such as lack of force feedback, joystick sensitivity, and time commitment restricted the simulator's overall effectiveness.
