Condylar resorption that occurs after orthognathic surgery was investigated in a large sample of patients treated in the Department of Oral and Maxillofacial Surgery of the Free University in Amsterdam, the Netherlands. The findings correspond with previous publications on this subject. In a 1-year follow-up study the role of intermaxillary fixation was investigated radiologically. In a group of 158 patients prone to show occurrence of condylar resorption, 24 (26.4%) of the 91 patients treated with intermaxillary fixation showed signs of condylar resorption. In the group of 67 patients treated without intermaxillary fixation only eight (11.9%) of the patients showed signs of reduced volume of the condyle. Avoidance of intermaxillary fixation seems to reduce the incidence of condylar resorption after orthognathic surgery in patients with a mandibular deficiency with high mandibular plane angle.
荷兰阿姆斯特丹自由大学口腔颌面外科治疗的大量患者样本中,对正颌手术后发生的髁突吸收情况进行了研究。研究结果与此前关于该主题的出版物一致。在一项为期1年的随访研究中,通过影像学手段对颌间固定的作用进行了研究。在一组158例易于出现髁突吸收的患者中,91例接受颌间固定治疗的患者中有24例(26.4%)出现了髁突吸收的迹象。在67例未接受颌间固定治疗的患者组中,只有8例(11.9%)患者出现髁突体积减小的迹象。对于下颌平面角较高的下颌后缩患者,避免颌间固定似乎可降低正颌手术后髁突吸收的发生率。
