Cephalometric measures correlate with polysomnography parameters in individuals with midface deficiency

To determine whether the cephalometric measurements studied could correlate with the polysomnographic parameters in order to provide a positive or negative predictive value for association with OSAS.本研究旨在明确所考察的头影测量指标（cephalometric measurements）与多导睡眠图参数（polysomnographic parameters）之间是否存在相关性，进而为二者与阻塞性睡眠呼吸暂停综合征（OSAS）的关联提供阳性或阴性预测价值。
