Importance: Prominotia has functional and esthetic impact for the child and family and proficiency in otoplasty requires experiential rehearsal.
Objectives: To design and validate an anatomically accurate, 3D printed prominotia simulator for rehearsal of otoplasties.
Methods: A 3D prominotia model was designed from a computed tomographic (CT) scan and edited in 3-matic software. Negative molds were 3D printed and filled with silicone. Expert surgeons performed an otoplasty procedure on these simulators and provided Likert-based feedback.
Results: Six expert surgeons with a mean of 14.3 years of practice evaluated physical qualities, realism, performance, and value of the simulator. The simulator was rated on a scale of 1 (no value) to 5 (great value) and scored 3.83 as a training tool, 3.83 as a competency evaluation tool, and 4 as a rehearsal tool.
Conclusions: Expert validation rated the otoplasty simulator highly in physical qualities, realism, performance, and value. With minor modifications, this model demonstrates valuable educational potential.
