코성형술과 동시에 시행하는 미끄럼 절골 턱성형술

Abstract

Chin retrusion and micrognathia are deformities that are commonly encountered in patients desiring rhinoplasty. Augmentation genioplasty in these patients improves the profile and enhances cosmetic result of rhinoplasty. For chin augmentation, either sliding osteotomy or implant insertion can be used. In alloplastic chin augmentation, rejection, infection of the materials, or resorption of the mandible can be a major problem. Horizontal sliding osteotomy of the mandibular symphysis with advancement of the mobilized segment can be the technique of choice to avoid these disadvantages. Here we report 2 cases of acquired nasal deformity and chin retrusion treated with simultaneous rhinoplasty and sliding genioplasty with a brief literature review.
