Educational Cadaveric Module for Teaching Percutaneous and Intranasal Osteotomies in Rhinoplasty.

Lateral osteotomies are essential to rhinoplasty and are performed through percutaneous or intranasal approaches. Both techniques are difficult to teach as they rely on tactile feedback. Thus, it is critical to understand trainee learning curves to minimize complications. Herein, we aim to (1) demonstrate an educational module for teaching lateral osteotomies and (2) examine potential differences in outcomes between the 2 surgical approaches when performed by trainees. After a hands-on cadaveric laboratory, trainees (n = 24) reported increased confidence in performing both types of osteotomies ( P < .0001). Completion of the bony cut was similar between intranasal and percutaneous osteotomies (96% vs 75%, P = .097), as was correct placement of the osteotomy (75% vs 67%, P = .53). Intranasal osteotomies were more likely to cause periosteal disruption ( P = .02). This pilot study demonstrates that cadaveric laboratories are an effective way to teach lateral osteotomies and that percutaneous osteotomies may be less likely to cause periosteal disruption in trainees' hands.
