Cephalometric variables that can be used to identify patients with obstructive sleep apnoea who are suitable for mandibular advancement splints and surgical maxillomandibular advancement are lacking. The aim of this pilot study was to describe the craniofacial characteristics of patients whose symptoms of obstructive sleep apnoea were successfully treated with mandibular advancement splints and who were subsequently considered for maxillomandibular advancement. We retrospectively compared the craniofacial characteristics of our patients with data from 2 previously published studies. There were significant differences between the 2 groups for ANB (p<0.000), overjet (p<0.0001), Go-Me (p<0.0002), and ANS-PNS (p<0.0009). Patients, whose symptoms improve with the use of mandibular advancement splints and are potential candidates for maxillomandibular advancement, may have unique craniofacial features consisting of bimaxillary retrusion characterised by a shorter maxilla and mandible, and a greater class II skeletal tendency. The results of this study should be viewed as a pilot. Further research is required.
目前缺乏可用于识别适合使用下颌前移矫治器和外科上颌下颌前移手术的阻塞性睡眠呼吸暂停患者的头影测量变量。这项初步研究的目的是描述那些阻塞性睡眠呼吸暂停症状通过下颌前移矫治器成功治疗且随后被考虑进行上颌下颌前移手术的患者的颅面特征。我们回顾性地将我们患者的颅面特征与之前发表的两项研究的数据进行了比较。两组在ANB（p<0.000）、覆盖（p<0.0001）、下颌角至颏下点距离（p<0.0002）和前鼻棘至后鼻棘距离（p<0.0009）方面存在显著差异。使用下颌前移矫治器症状改善且可能适合上颌下颌前移手术的患者，可能具有独特的颅面特征，包括双颌后缩，其特点是上颌骨和下颌骨较短，且具有更大的II类骨骼倾向。本研究结果应视为初步结果。还需要进一步研究。
