Our objective was to evaluate the relationship between posterior facial cephalometric measures and obstructive sleep apnea syndrome (OSAS). We used a consecutive sample of 60 patients with OSAS who underwent upright lateral cephalograms, uvulopalatopharyngoplasty (UPPP), and preoperative and postoperative polysomnography. Successful responders to UPPP were arbitrarily defined as having a respiratory disturbance index reduced to fewer than 20 events per hour. Standard cephalometric measurements were used. Posterior facial height measures were constructed, based on a plane perpendicular to the Frankfort horizontal placed at hyoidale. The total and lower airway lengths were shorter and posterior mandibular height was longer in UPPP responders compared to nonresponders (p < or = .05). There was no difference between the two groups by standard cephalometric measurements. Responders and nonresponders to UPPP have significant differences in posterior airway measures that are not reflected in standard cephalometric measures. Airway length likely is a critical factor in OSAS and surgical response.
我们的目的是评估面部后段头影测量指标与阻塞性睡眠呼吸暂停综合征（OSAS）之间的关系。我们连续选取了60例接受直立位侧位头影测量、悬雍垂腭咽成形术（UPPP）以及术前和术后多导睡眠图检查的OSAS患者。UPPP治疗成功的反应者被随意定义为呼吸紊乱指数降至每小时少于20次事件。采用标准头影测量方法。基于在舌骨处垂直于法兰克福水平线的平面构建面部后段高度测量指标。与无反应者相比，UPPP反应者的气道总长度和下气道长度较短，下颌后段高度较长（p≤0.05）。通过标准头影测量，两组之间没有差异。UPPP的反应者和无反应者在气道后段测量指标上存在显著差异，而这些差异在标准头影测量中并未体现。气道长度可能是OSAS及手术反应的关键因素。
