Background: Angloplasty is the most common procedure in facial contouring surgery among Asians. However, to achieve satisfactory results during procedures aimed at altering the lower facial contour, the shape of the mandible and the chin area in particular is an important consideration. In cases of reoperation for further improvement after angloplasty, surgeons should consider performing a genioplasty to improve the shape of the chin.
Methods: From March of 2010 to August of 2012, 52 women who were dissatisfied with results of angloplasty and wanted a slimmer lower face underwent genioplasty and revision angloplasty. The procedures included narrowing genioplasty and contouring of the lower border of the mandible from the parasymphysis area to the previously resected area.
Results: All patients were satisfied with their facial appearance, which had become slender when viewed from the front. There were no notable complications. No patient experienced permanent sensory numbness of the lower lip. Two patients complained of submental bulges and were treated postoperatively using laser-assisted liposuction.
Conclusion: When performing revision surgery to restore the contour of the mandible, the surgeon should consider the shape of the mandible as a whole to create a slender face, which is achievable by simultaneous narrowing genioplasty and contouring of the lower border of the mandible.
