Evaluating Simulator-Based Teaching Methods for Endoscopic Sinus Surgery.

Area of Science:

• Medical Education
• Surgical Simulation
• Otolaryngology

Background:

• Various simulator systems exist for endoscopic sinus surgery (ESS) training, including cadavers, virtual reality, and realistic models.
• Previous studies validated these simulators independently, but direct comparative outcome analyses were lacking.
• Novice trainees require effective tools to acquire fundamental ESS skills before operating room entry.

Purpose of the Study:

• To directly compare the utility of high-fidelity and low-fidelity ESS trainers against a control group (no simulator exposure).
• To evaluate the impact of different simulator fidelities on novice trainees' acquisition of basic ESS skills.

Main Methods:

• Thirty-four first-year medical students were randomized into three groups: high-fidelity simulator, low-fidelity simulator, and control.
• All participants received basic sinus anatomy and instrumentation training.
• Performance was assessed via recorded cadaveric dissections, graded by an expert for anatomical identification, endoscopic competency, and task completion.

Main Results:

• No statistically significant differences in performance were observed between the three groups regarding anatomical identification, endoscopic competency, or basic task completion.
• A combined analysis of high-fidelity and low-fidelity simulator groups showed a significant improvement in time to complete basic anatomy tasks (P = .043) and total procedure time (P = .041).
• This study represents the first direct comparison of high-fidelity, low-fidelity, and control groups for ESS simulator training outcomes.

Conclusions:

• While no significant differences in basic skill acquisition or task performance were found among novice trainees using high-fidelity or low-fidelity ESS simulators versus a control group, simulator use may enhance efficiency.
• The study suggests that ESS simulators, regardless of fidelity, may contribute to reduced completion times for fundamental anatomical learning and procedural tasks.
• Further research could explore long-term skill retention and transferability to actual surgical performance.
