Soft tissue changes associated with advancement genioplasty performed concomitantly with superior repositioning of
Abstract:
A retrospective study of the osseous and soft tissue changes of the chins of ten patients treated for vertical maxillary excess by Le Fort I osteotomy and advancement genioplasty was undertaken. The patients were characterized by excessive lower anterior facial height, obtuse or normal nasolabial angles, prominent maxillary incisors, lip incompetence, everted lower lips, anterior open bites, lack of chin prominence, and excessive chin height. A change in the proportion of osseous to soft tissue of 1.0 to 0.87 was obtained by advancement genioplasty and concomitant superior repositioning of the maxilla by Le Fort I osteotomy.
