Role of genioplasties in various chin deformities

Abstract

Aim and Objectives: The goal of surgical-orthodontic treatment of chin deformities is to achieve maximum function, esthetics, and stability. The objective of our study is to evaluate the role of genioplasties in various chin deformities. Materials and Methods: Twelve adult patients who manifested various types of chin deformities were treated. In eight patients, advanced genioplasty alone or in combination with other surgical procedures such as premaxillary osteotomy, gap arthroplasty, bilateral vertical ramus osteotomy, and advancing and sliding genioplasty was performed. Four patients were treated by reduction genioplasty alone or in combination with vertical ramus osteotomy. Results: Results were more predictable and stable in case of chin advancement procedures as compared to reduction genioplasty. Conclusion: It was observed that the chin should not be completely denuded, muscular attachment on the lower part of the chin should always be maintained, if possible.
