Learning Modern Laryngeal Surgery in a Dissection Laboratory.

Area of Science:

• Otolaryngology
• Surgical Education
• Anatomical Research

Background:

• Laryngeal cancer surgery demands high precision.
• Training opportunities are limited due to specimen availability and ethical concerns.
• Specialized centers handle most laryngeal malignancy cases.

Purpose of the Study:

• To establish a reproducible ex vivo animal model for laryngeal surgery training.
• To facilitate learning and refinement of endoscopic and open laryngeal surgical techniques.
• To provide a cost-effective and accessible training alternative.

Main Methods:

• Utilized porcine and ovine larynges as anatomical models.
• Detailed surgical steps for transoral laser surgery, open partial horizontal laryngectomy, and total laryngectomy.
• Integrated endoscopic and exoscopic views for enhanced anatomical comprehension.

Main Results:

• Demonstrated the feasibility of the ex vivo laryngeal laboratory model.
• Successfully implemented the method in three "Lary-Gym" dissection courses.
• Validated the anatomical similarity and suitability of animal models for surgical simulation.

Conclusions:

• Ex vivo animal larynges offer a viable and effective platform for laryngeal surgery training.
• This method enhances understanding of complex laryngeal anatomy and surgical procedures.
• The model supports the development of skills for various laryngeal surgical interventions, with future potential for robotic training.
