Abstract
An adequately balanced proportion and symmetry of all facial features are the requisites for a beautiful face, and the chin plays an important role on facial aesthetics. Sliding genioplasty (SG) is a well-established method for changing the position, size or shape of the mandibular symphysis using autogenous material. We report our result from a 10-year review of our experience with SG. 18 patients (11 retrognathia/microgenia, 3 asymmetry, 1 mucoepidermal cancer of submandibular gland s/p free iliac bone flap reconstruction, 1 cleft lip and palate, 1 Treacher-Collins syndrome, 1 class Ⅲ malocclusion ), aged 19 to 65 years (mean age, 30.3 years), underwent SG alone (9 patients) or with concomitant facial contouring procedures (9 patients) during the year 1994 to 2004. Mean value of chin advancement was 8 mm. Unilateral mental nerve injury was noted in 2 patients and immediate repair was performed. Paresthesia in the involved area resolved in few months. All patients were very satisfied with the cosmetic result. By performing SG, the chin can be moved not only in the sagittal plane but also in the vertical and transverse planes of space. Our experience demonstrates the versatility and excellent esthetic results with the procedure.
