摘要/Abstract

摘要： 目的：研究阻塞性睡眠呼吸低通气暂停综合征(obstructive sleep apnea hypopnea syndrome，OSAHS)患者舌后区上呼吸道的CT影像，探讨舌后区呼吸道狭窄的原因。方法：对经多导睡眠监测系统(polysomnography, PSG)确诊的100例OSAHS患者，采用螺旋CT行上呼吸道连续扫描，测量舌后区呼吸道横截面积，对存在舌后区呼吸道狭窄（24例）和无舌后区呼吸道狭窄（76例）的两组患者进行对比研究。结果：两组患者的一般临床资料无明显差别，舌后区狭窄组的舌后区呼吸道左右径、前后径明显小于非狭窄组，狭窄组的咽后壁、咽侧壁软组织厚度、舌体宽度、舌体长度和舌体截面积等CT测量数据明显大于非狭窄组。结论：24%的OSAHS患者存在舌后区上呼吸道狭窄，除舌体肥厚外，咽侧壁和咽后壁的软组织增厚也是导致舌后区呼吸道狭窄的重要原因。

Abstract: Objective: To study the CT imaging of upper airway at the lingual region stricture for obstructive sleep apnea hypopnea (OSAHS) patients and to explore its meaning. Methods: One hundred patients with OSAHS were enrolled in this study and divided into two groups :the stricture group (24 cases) and the non-stricture group (76 cases). The dimension of the lingual region airway, the thickness of the retro-pharyngeal and the lateral pharyngealtissue， and the width and length of the tongue were determined. Results: There was no difference of age, BMI, AHI and pulse oxygen between the stricture group and the non-stricture group. The coronal and the arrow diameters of the stricture group were less than those of the non-stricture group. The thickness of the retropharyngeal and lateral pharyngeal wall, and the width and length of the tongue of the stricture group were larger than those of the non-stricture group. Conclusion: Lingual region stricture occurs in about 24% of patients with OSAHS, which may be caused by the incrassation of the retropharyngeal and lateral pharyngeal wall and fleshy tongue.
