Development of a Microsurgical Simulator for Laryngeal Surgery: A Novel Training Device

Area of Science:

• Otolaryngology
• Surgical Education
• Medical Simulation

Background:

• Microsurgical skills training for endolaryngeal procedures is crucial for otolaryngologists.
• Existing simulators may lack anatomical realism, affordability, or modularity for diverse training needs.

Purpose of the Study:

• To develop and validate a modular, low-cost, and anatomically realistic microsurgical simulator for endolaryngeal training.
• The simulator aims to facilitate training in CO2 laser procedures and microsuturing.

Main Methods:

• A dual-module simulator was created using porcine larynges, featuring a fixation unit and a flexible laryngoscope holder.
• Junior and senior otolaryngologists performed standardized tasks including vocal fold dissection, microsuturing, and laser cordectomy.
• Participants completed surveys assessing realism, usability, and educational value.

Main Results:

• Twenty-one otolaryngologists evaluated the simulator, reporting high satisfaction (mean score 4.71/5).
• Participants reported significant perceived training benefits in hand-eye coordination, basic laser surgery instrumentation, and bimanual dexterity.
• High agreement (81%-100%) was observed across survey items, indicating strong user acceptance.

Conclusions:

• This novel porcine-larynx simulator offers a practical, realistic, and educationally valuable platform for microlaryngeal skills training.
• Its affordable, adaptable design has the potential for widespread adoption in surgical education programs.
