Aesthetic outcomes and morphological changes in chin parameters after mandibular distraction and subsequent advancement genioplasty in patients with mandibular micrognathia

Despite the wide uses of mandibular distraction osteogenesis (MDO), no study appears to have evaluated the use of MDO and subsequent advancement genioplasty. This study addressed lower facial third aesthetics in a consecutive series of subjects with micrognathia who underwent MDO and subsequent advancement genioplasty. Standard cephalometric measurements were performed pre-MDO, at the end of consolidation, and at 1 week, 6 months, and 12 months after genioplasty. At the end of follow-up, questionnaires were given to measure patient satisfaction.
