A new method for training of ear framework creation by silicon dental impression material

Area of Science:

• Plastic Surgery
• Biomaterials Science
• Surgical Training

Background:

• Microtia reconstruction often requires complex cartilage framework creation.
• Novice surgeons need effective training methods for ear framework carving.
• Simulating autologous costal cartilage is crucial for realistic practice.

Purpose of the Study:

• To present a novel, cost-effective training method for creating cartilage frameworks for microtia total ear reconstruction.
• To provide a reproducible simulation for practicing surgical techniques.
• To enhance surgeon proficiency in ear framework design and carving.

Main Methods:

• Utilizing silicone dental impression material to mimic the texture and consistency of costal cartilage.
• Employing standard wood carving instruments for framework sculpting.
• Simulating the sequential steps of actual ear reconstruction surgery on the material replica.

Main Results:

• The silicone dental impression material demonstrated comparable consistency and texture to real costal cartilage.
• The carving process using wood instruments allowed for detailed three-dimensional framework creation.
• The simulated surgical steps provided a practical training experience.

Conclusions:

• This novel training method offers a viable and accessible way for surgeons to practice ear framework creation for microtia.
• The silicone replica technique enhances surgical skill development and potentially improves patient outcomes.
• This approach facilitates learning and improvisation for novice surgeons in a simulated environment.
