Summary
New silicone ear models effectively train surgeons in otoplasty techniques for protruding ears. This teaching tool helps beginners and experts master standard auricular deformities, reducing complications.
Area of Science:
- Plastic Surgery
- Medical Education
- Anatomy
Background:
- Otoplasty is a common cosmetic procedure to correct protruding ears.
- Mastery of surgical techniques is crucial to avoid complications from incorrect indications or methods.
- Standardized training models are valuable for learning surgical steps.
Purpose of the Study:
- To develop and evaluate novel silicone ear models for otoplasty training.
- To assess the effectiveness of these models in teaching standard auricular deformity correction techniques.
Main Methods:
- Two silicone ear models were created based on CT scans: one for conchal resection, another for antihelical fold creation.
- 91 otorhinolaryngology residents evaluated the models during four surgery courses.
- Participants completed questionnaires assessing the models' helpfulness and technical aspects.
Main Results:
- Nearly all participants found the training models very helpful or good.
- Model evaluation scores ranged from 2.0 to 2.6 (1=very good, 4=inadequate).
- The models proved effective for learning various otoplasty techniques.
Conclusions:
- The developed silicone ear models are a valuable teaching tool for otoplasty.
- These models facilitate learning standard surgical techniques for auricular deformities.
- Effective training with these models can potentially reduce otoplasty complications.
