Advancing and Lengthening Genioplasty in Contouring of the Receding and Short Chin.

[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.
