- Abstract
Objective: 1) Develop a novel low cost task trainer which appropriately simulates the basic steps involved in a tonsillectomy procedure for the novice trainee. 2) Assess this task trainer for feasibility, face validity, usability, and content validity using a group of expert observers. Method: The task trainer was developed to reproduce all steps of the tonsillectomy procedure using pieces of steak with adherent connective tissue to simulate the tonsil for electrocautery dissection. Pediatric otolaryngology attendings and fellows were surveyed using a 5‐point Likert scale to assess ease of use, realism, and perceived utility. Results: The model consists of a Styrofoam head with cut‐out oropharynx and steak pieces suspended by metal clips and wired to an electrocautery unit. Surgeons use a headlight, grasp the muscle, and electro‐dissect it away from the fat. Cost of the model was twenty US dollars. Ten attending pediatric otolaryngologists and 4 pediatric otolaryngology fellows completed simulated tonsillectomies and surveys. Participants rated a median realism score of 4 out of 5 (very realistic) and ease of use a median 5 out of 5 (simple and intuitive). All participants agreed residents would be better prepared for real tonsillectomies after using the model. Conclusion: Production and use of a tonsillectomy task trainer is a feasible and inexpensive endeavor for training programs and may provide appropriate usability and fidelity in simulating tonsillectomy for trainees. Face and content validity were confirmed by expert observers. Further study will assess validity and effectiveness for teaching and assessment.
