Area of Science:

  • Otolaryngology
  • Surgical Education
  • Medical Simulation

Background:

  • Phonosurgery demands high technical skill and precise tissue handling.
  • Current training methods present challenges for novice residents in developing essential phonosurgical techniques.
  • A need exists for accessible, cost-effective training tools in phonosurgery.

Purpose of the Study:

  • To develop and validate a low-cost phonosurgery simulator for practicing microlaryngeal skills.
  • To assess the simulator's face and content validity among experienced otolaryngologists.

Main Methods:

  • A simulator was constructed using inexpensive materials like plywood, PVC pipe, rubber bands, and plastic wrap.
  • Laryngeal modules were designed to simulate basic instrumentation, papilloma debulking, and lesion excision.
  • Attending otolaryngologists (n=16) evaluated the simulator's realism and utility via a post-simulation questionnaire.

Main Results:

  • 89% of participants confirmed the simulator's content validity, noting its realistic simulation of actual phonosurgical cases.
  • 100% of participants agreed on the simulator's face validity, deeming it adequate for improving resident competency.
  • All participants expressed interest in utilizing the simulator for resident training.

Conclusions:

  • The developed low-cost phonosurgery simulator shows significant potential for enhancing surgical education.
  • Its realistic design, modularity, and affordability make it a valuable tool for phonosurgical training and preparation.
  • This simulator can bridge the gap in practical skill acquisition for novice surgeons in phonosurgery.
