Bow-tie genioplasty: a novel technique for sagittal reduction of chin using segmental rotation setback movement

Abstract

Since genioplasty was first described by Hofer in 1942, various genioplasty techniques have been developed and modified. However, the literature on sagittal reduction genioplasty is scarce. Most of these are modifications of the traditional two methods-grinding and sliding setback, with potential complications. The purpose of this article is to introduce a novel technique (bow-tie genioplasty) to achieve favorable sagittal reduction of the chin without potential complications from the traditional methods. Bow-tie genioplasty is a technique that uses bilateral wedge-shaped osteotomy on the chin. This osteotomy was designed to rotate the distal segment posteriorly, as shown in the diagrams. We present an example of a patient with a protruding chin treated with bow-tie genioplasty. There were no significant adverse effects or complications that could be triggered by the traditional setback methods, and the surgeon and patients were satisfied with the esthetic results. Bow-tie genioplasty is the most innovative technique for sagittal reduction of the chin. This novel technique may optimize the chin setback effect while minimizing the complications associated with the traditional method.
