Abstract:
OBJECTIVETo investigate a technique for correction of severe microgenia.
METHODSThe mandibular symphysis was exposed through intraoral mucous incision. Two parallel osteotomies were performed under mental foramen. The mobilized segments were advanced like two steps and fixed rigidly with miniplate.
RESULTSFrom June, 2004 to Dec, 2005, 10 cases with severe microgenia were treated with this technique. The duration of follow-up was six months. The mean chin advancement was 1.1 cm and the mean chin vertical increase was 0.7 cm. All the patients healed very well with satisfactory aesthetic result.
CONCLUSIONSWith this two-step genioplasty, the chin can be moved to ideal position with a natural appearance. It is a reliable method for severe microgenia.
