Feasibility of Sheep Auricular Cartilage as a Teaching Tool for Training in Slicing Techniques for Cartilage Tympanoplasty.

There are temporal bone dissection workshops organised all-over the world, however, there is no dedicated teaching program to train in slicing techniques for cartilage tympanoplasty. The aim of the study is to train the otologists in slicing techniques in cartilage tympanoplasty using sheep auricular cartilage as a teaching model and to evaluate the impact of the training on the participants. A total of 98 otologists have been trained in slicing techniques using cartilage slicer during 7 workshops organised at our centre from January 2016 to January 2020 for a total of 6 days for each trainee. Each trainee performed slicing techniques in cartilage tympanoplasty using 5 sheep pinna. Evaluation of the impact of the training was done in terms of assessment of improvement in performance. The feedback forms evaluated the training technique with sheep cartilage, its feasibility and usability as a model for teaching. The impact of the training on the overall performance of the trainee was assessed in terms of confidence, ability and speed in performing tasks related to slicing and cartilage tympanoplasty. The simulation in slicing techniques using sheep auricular cartilage has a teaching potential to improve the surgical outcomes of tympanoplasty as assessed by the performance of the participants.
