Validating a New Surgical Gouge for Autogenous Ear Reconstruction During Simulated Microtia Workshops

Abstract

Autologous ear reconstruction remains a gold standard surgical technique for the treatment of external ear deformities. This highly technical procedure requires experience, an understanding of aesthetic principles, and a surgical approach that can consistently produce optimal results. As an experienced microtia surgeon having trained under Dr Satoru Nagata, the senior author has emphasized the importance of appropriate surgical tools during this procedure. Here, we present results of a novel surgical handle and gouge meant to optimize complex cartilage carving. The senior author regularly holds microtia workshops to help train individuals around the United States. During 2 of such workshops held in 2022, participants were given access to both the standard, commercially available surgical gouge as well as a prototype of a novel surgical gouge developed by the authors. Participants were then given a Likert-scale survey to assess their subjective feedback for both tools. Twenty-seven total participants completed the postworkshop survey. Cumulatively, the results demonstrated that participants rated the custom gouge significantly higher than its counterpart (4.2 versus 3.2, P<0.001). They also had a significantly higher likelihood of using the custom gouge again (4.1 versus 3.2, P=0.023). The custom gouge designed by the senior author demonstrated higher subjective ratings when compared with what is currently available on the market. This serves as a primary validation study that demonstrates feasibility for further assessment in a true operative setting.
