“…The same applies for animal specimens, mainly because of the different anatomy and the plasticity of the auricular cartilage. Using fresh porcine auricles for training otoplasty, it is possible to form antihelical folds with a suture technique, but no other procedures are applicable [9]. Training on artificial models has a lot of advantages compared to human or animal specimens, provided they imitate the real surgical situation as far as possible.…”

Otoplasty for the correction of protruding ears is characterized by various techniques and a common and popular cosmetic procedure. For the surgeon, whether beginner or advanced, it is essential to understand the principles and master techniques for standard auricular deformities before applying further sophisticated methods, because a lot of complications and failures are caused by wrong indication and incorrect surgical techniques. The different surgical steps are best learned from teaching models. Therefore, we developed two different silicone models of protruding ears with moderate auricular deformities: one with conchal hyperplasia for the training of conchal resection, and one without antihelix for creating an antihelical fold by suturing technique, based on computed tomography scans of patients. The silicone ear models were evaluated during four standardized surgery courses for residents in otorhinolaryngology by 91 participants using specially designed questionnaires. Nearly all participants rated the training on the auricular models as very helpful (n = 51) or good (n = 31); the scores for the different techniques and properties of the models ranged from 2.0 to 2.6 in a range from 1 (very good) to 4 (inadequate). The good results demonstrate the possibility for learning different surgical otoplasty techniques with this newly designed teaching tool.

“…There are currently limited platforms available for otoplasty training. 9,10 Whilst cadaveric dissection plays an important role for many operations, its role in otoplasty is limited, with preserved ear cartilage becoming considerably softer with fixation, making the surgical steps more difficult to carry out. 16 Furthermore, most UK centres have limited access to cadaveric models because of the high costs and need for specific facilities, making this model less practical for implementation into training programmes.…”

“…11 The ex vivo porcine auricular model has been previously described for use as a simulation model for otoplasty. 10 However, in order to establish the validity of the simulation model, it needs to be subjected to a comprehensive assessment of its realism (face validity) and usefulness for training (content validity). We have been able to validate the porcine model for use in otoplasty across all domains assessed.…”

Objective To perform a validation assessment of a novel porcine ex vivo model for otoplasty training. Methods A total of nine otolaryngology trainees performed a standard approach otoplasty on a porcine ear. They completed a series of tasks including posterior skin incision, anterior scoring, Mustardé suture placement and concha–mastoid suture placement. Trainees completed a post-task questionnaire assessing face validity, global content validity and task-specific content validity. Results Trainees’ median scores for the porcine model were: 4 for face validity (interquartile range, 3–4), 5 for global content validity (interquartile range, 4–5) and 4 for task-specific content validity (interquartile range, 4–4). Conclusion This study is the first to formally validate the ex vivo porcine auricular model as a useful tool for training in otoplasty. The model should be incorporated into simulation training for otoplasty in order to improve learning, enable acquisition of specific surgical skills and improve operative outcomes.

“…Pese a ello, se han publicado pocas investigaciones que describan su experiencia en la simulación de la otoplastia. 15,16 Esto se debe a que, por un lado, los modelos animales poseen una desventaja anatómica obvia, así como disponibilidad y almacenamiento más complejos. Con respecto a modelos sintéticos, la literatura disponible muestra una debilidad común: todos presentan una sola capa que no emula la piel y el cartílago por separado, además de que no cuentan con una adecuada validación.…”
