Peritonsillar Abscess Simulator: A Low-Cost, High-Fidelity Trainer.

Area of Science:

• Medical Education
• Surgical Simulation
• Emergency Medicine Training

Background:

• Peritonsillar abscess (PTA) is a common deep head and neck infection managed by emergency medicine physicians.
• Simulation training is increasingly recognized for improving resident education and patient safety.
• Effective PTA management requires precise needle aspiration to avoid complications.

Purpose of the Study:

• To develop and evaluate a reusable, low-cost peritonsillar abscess (PTA) simulator.
• To assess the simulator's fidelity and educational value for emergency medicine (EM) and otolaryngology (OTL) trainees.
• To improve trainee confidence and dexterity in performing PTA needle aspiration.

Main Methods:

• Fabrication of a low-cost PTA simulator using silicone molds and readily available materials.
• Evaluation of the simulator using The Michigan Standard Simulation Experience Scale (MiSSES) with 21 EM and OTL participants.
• Statistical analysis comparing participant ratings based on training level, specialty, and experience.

Main Results:

• The simulator received high fidelity ratings (4.6/5) and teaching quality scores (4.9/5) on the MiSSES.
• Participants reported increased confidence and found the simulator valuable for learning PTA needle aspiration.
• No statistically significant differences were found between groups, indicating broad applicability.

Conclusions:

• The developed PTA simulator offers a high-fidelity, low-cost training solution for EM residency programs.
• This reusable tool can enhance procedural skills and confidence in managing peritonsillar abscesses.
• Widespread adoption of this simulator can improve patient outcomes through better-trained physicians.
