Abstract:
The aim of this study was to compare the postoperative complications during genioplasty using piezosurgery devices or traditional rotating drills. Forty patients underwent genioplasty to solve their chin anomalies. This study showed that, using piezosurgery, pain and swelling were reduced compared to the traditional technique in the immediate postoperative period of healing (within 15 days). Paresthesia was observed in all patients up to 15th postoperative day, independently of the used surgical technique, but at the sixth postoperative month it was completely absent.Keywords:

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.

Background: In East Asia, receding and short chin are common complaints of patients who do not have satisfied lower face. In most former studies, receding and short chin are considered and treated separately. But during the clinical work, the authors found that, in many patients, neither vertical elongation nor horizontal advancement of the chin is sufficient to achieve a harmonious result. In regards of this problem, the authors performed an advancing and lengthening genioplasty and the results were aesthetically satisfactory. Study Design: Twenty-six patients with receding and short chin were involved in this study. After presurgical computed tomography (CT) scan, advancing and lengthening genioplasty with/without other osteotomy operations were performed on all the patients. All patients underwent postoperative CT scan and had at least 3-month follow-up. Result: All patients were satisfied with the final results. According to the postoperative CT images and 3-month follow-up, no severe complications occurred. Conclusion: For patients with receding and short chin, advancing and lengthening genioplasty is a reliable therapy to obtain harmonious East Asian lower face.

Facial analysis for chin deformities evaluates the perioral structures independently and their relationship to the entire face. Chin deformities in the absence of malocclusion can be treated by a genioplasty. Patient evaluation and preoperative planning and the operative technique for an osseogenioplasty are outlined with clinical reports to illustrate.
