A retrospective study was performed to examine the occurrence of condylar atrophy in connection with orthognathic surgery. Patients with high-angle mandibular deficiency (n = 29) were selected from among those who underwent bimaxillary osteotomy (n = 93) during the period from January 1987 through December 1990. This group of 29 was examined for shortening of the ascending ramus of the mandible because of condylar resorption. In 9 of these 29 (31%), the ramus had resorbed more than 2 mm, or more than 6% of the total length of the ramus. All 9 of these patients were female. There was no correlation between resorption and age, the amount of retrognathism, or the presence of preoperative temporomandibular joint dysfunction. Female patients with high-angle retrognathism should be informed of the possibility of postoperative condylar resorption and should be followed with radiographic controls for at least 2 years after surgery.
进行了一项回顾性研究，以检查正颌外科手术相关的髁突萎缩情况。从1987年1月至1990年12月期间接受双颌截骨术（n = 93）的患者中，选取高角型下颌后缩患者（n = 29）。对这29例患者检查因髁突吸收导致的下颌升支缩短情况。在这29例患者中，有9例（31%）升支吸收超过2mm，或超过升支总长度的6%。这9例患者均为女性。吸收与年龄、下颌后缩程度或术前颞下颌关节功能障碍之间无相关性。应告知高角型下颌后缩的女性患者术后髁突吸收的可能性，并在术后至少2年进行影像学随访。
