Swyer-James syndrome is considered to be a post-infectious form of bronchiolitis obliterans, pathologically defined by the presence of submucosal and peribronchiolar fibrosis with destruction and obliterative scarring of the small airways.

Swyer-James综合征被认为是闭塞性细支气管炎感染后形成的，病理表现为出现黏膜下及支气管周围纤维化并有小气道破坏和疤痕组织，SJS是一类有不同临床表现的综合征，这些表现主要与囊状支气管扩张是否出现有关。

During CT scan,patients were in supine position, and the teeth in the middle of the contactposition on the jaw; and maintain a static head and body during the scanningprocess, did not swallow; measurement parameters including: soft palatelength, maximum thickness of the soft palate, pharynx lateral spacing, uvula length and base width of the free edge ofsoft palate to the throat wall spacing, velopharyngeal cross-sectional area,angina cross-sectional area,thickness of retropharyngeal wall.

随机对10例患者进行系统的腭咽CT测量，测量时间为术前、术后3个月、术后6个月；测量方法为：患者在清醒状态下进行平静呼吸时的上气道CT扫描，范围自听眶线至声门。利用CT工作站进行三维重建和测量。CT扫描时患者取仰卧位，牙齿处于正中颌的接触位上。
