To compare the CT scan results in OSAS patients and normal adults so as to explore its value in measuring upper airway structure.
53 patients with OSAS and 53 normal adults were included in the study. The upper airway from roof of nasopharynx to glottis was evaluated with the use of a Phlips Tomoscan AV Expander E1 spiral scanner. The area and the dimensions of palate, uvula, lingua and epiglottis region was studied, and the thickness of retropharyngeal and lateral pharyngeal tissue were evaluated, too.
There were obviously differences between OSAS patients and normal adults in the areas of palate, uvula, lingua, and there are differences of dimension and thickness in different sites.
The study suggests that there is a obviously difference between the patients with OSAS and normal adult in upper airway by CT scan. The anatomic structure of upper airway is one of causes of OSAS.
比较阻塞性睡眠呼吸暂停低通气综合征（OSAS）患者与正常成年人的CT扫描结果，以探讨其在上气道结构测量中的价值。
本研究纳入53例OSAS患者和53例正常成年人。使用飞利浦Tomoscan AV Expander E1螺旋扫描仪评估从鼻咽顶部到声门的上气道。研究了腭、悬雍垂、舌和会厌区域的面积和尺寸，并评估了咽后和咽侧组织的厚度。
OSAS患者与正常成年人在腭、悬雍垂、舌的面积方面存在明显差异，不同部位在尺寸和厚度上也存在差异。
该研究表明，通过CT扫描，OSAS患者与正常成年人在上气道方面存在明显差异。上气道的解剖结构是OSAS的病因之一。
