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.
对10例接受Le Fort I型截骨术和前移颏成形术治疗垂直上颌骨过长的患者的颏部骨组织和软组织变化进行了回顾性研究。这些患者的特征为下前部面部高度过大、鼻唇角钝或正常、上颌切牙突出、唇部闭合不全、下唇外翻、前牙开合、颏部不突出以及颏部高度过大。通过前移颏成形术以及Le Fort I型截骨术同时对上颌骨进行上移，骨组织与软组织的比例从1.0变为0.87。
