摘要: 目的 通过256排螺旋CT测量阻塞性睡眠呼吸暂停低通气综合征 (OSAHS) 患者上气道横截面积及容积, 评估OSAHS患者上气道阻塞平面, 为临床诊断及治疗提供帮助.方法 随机选取确诊为OSAHS患者178例, 无打鼾的健康人110例作为正常对照组, 应用Philips 256排螺旋CT, 测量各组平静呼吸状态及Müller状态下 (闭口鼻的状态下用力吸气) 上气道各区最窄平面横截面积及各区气道容积.结果 比较平静呼吸与Müller状态, OSAHS组除会厌后区横截面积、容积, 其余各组参数间差异有统计学意义 (P<0.05) , 腭后区及舌后区容积差异有统计学意义 (P<0.05) ;正常对照组舌后区横截面积有差异, 其余各指标差异无统计学意义 (P>0.05) .结论 用256排螺旋CT测量OSAHS患者上气道, 阻塞平面多位于腭后区及舌后区.上气道容积的CT测量可以用来并且能更好地评估OSAHS患者上气道阻塞情况.

Abstract: Objective To measure the upper airway of obstructive sleep apnea hypopnea syndrome by 256 slice spiril CT, and to access the airway obstruction plane with the airway plane data in OSAHS patients.Through these measurements, we can provide assistance for clinical diagnosis and treatment.Methods This study randomly selected 178 patients diagnosed with OSAHS and 110 cases non-snoring healthy people as the control group by the Philips 256 slice CT.Under the nasopharyngeal area, velopharyngeal area, glossopharyngeal area, epiglottis area, we measured the cross-sectional area and volume of the narrowest plane in the two groups of quiet respiration and Müller status.Results The OSAHS group underwent quiet respiration and Müller status during CT scanning, and the two states about epiglottis area in cross-sectional area and volume had no significant difference, Other groups had differences between the parameters.There was a significant difference in the volume about velopharyngeal area and glossopharyngeal area. In the control group undergoing quiet respiration and Müller status during CT scanning, there was difference in velopharyngeal cross-sectional area.Other parameters had no significant difference.Conclusions The obstruction plate of OSAHS patients with 256-slice spiril CT measurement is mostly in the velopharyngeal area and glossopharyngeal area. The volume measurement of upper airway by CT can predict airway obstruction plate in patients with OSAHS.-
