Phonosurgery Training in Human Larynx Preserved with Thiel's Embalming Method

Area of Science:

• Otolaryngology
• Surgical Education

Background:

• Phonosurgery training requires realistic anatomical models.
• Current models may lack tissue pliability and realism.

Purpose of the Study:

• To evaluate the suitability of Thiel's embalmed larynges for phonosurgery training.
• To compare Thiel's method with traditional formalin preservation.

Main Methods:

• Ten Thiel's embalmed and ten formalin-preserved larynges were used.
• Phonosurgery techniques (microflap, injection laryngoplasty) were performed.
• A survey assessed participant perception of realism and utility.

Main Results:

• Thiel's embalmed larynges offered superior vocal cord pliability and tissue quality.
• Participants reported a realistic sensation and positive training experience.
• Models were deemed useful for improving phonosurgery skills and confidence.

Conclusions:

• Thiel's embalmed human larynges provide a realistic and safe model for endolaryngeal procedure training.
• This method overcomes limitations of anatomical variation and rigidity found in other models.
• It offers a unique, contamination-free training solution for phonosurgery.
