摘要
目的:应用多层螺旋CT三维重建技术,对OSAHS患者进行上气道成像,探讨上气道鼻咽、腭咽、舌咽、喉咽区容积及变化率与AHI、LSaO_2的相关性。方法:(1)对51例经多导睡眠监测检查的OSAHS患者分别按AHI、LSaO_2值进行病情分度;(2)通过多层螺旋CT三维重建成像,测量患者于平静呼吸、闭口堵鼻深吸气(Müller's)时相上气道各区域容积,计算容积变化率,观察上气道顺应性;(3)分别将CT所测得的各区域容积值与AHI、LSaO2进行单因素相关分析。结果:不同程度OSAHS患者上气道最小容积均位于腭咽区;腭咽区不同呼吸时相的容积与AHI呈负相关,与LSaO2呈正相关;喉咽区平静呼吸时相的容积与AHI呈负相关;舌咽区Müller's呼吸时相的容积与LSaO2呈正相关。结论:(1)在OSAHS的诊断中,上气道腭咽区容积可不同程度反映AHI、LSaO_2高低;(2)CT三维重建上气道容积测量对于评价OSAHS患者的上气道顺应性具有良好的应用价值。
Objective：To study the relationship among upper airway volume of naso-pharyngeal,yelo-pharyngeal,glosso-pharyngeal,hypo-pharyngeal area which measured by spiral computed tomography three-dimensional reconstruction technique,apnea hypopnea indexes,and the lowest oxygen saturation in patients with OSAHS.Method：（1）fifty-one patients with OSAHS were received polysomnography,and then were divided into groups by the AHI,LSaO2 values.（2）To measure upper airway volume at normal breath and Müller maneuver state using spiral computed tomography three-dimensional reconstruction technique of CT measurement,and to calculate volume change rate and observe the upper airway compliance.（3）To analyses the relationship between upper airway volume and AHI,LSaO2 values.Result：The smallest upper airway volume of OSAHS was at the velo-pharyngeal level;the volume of velo-pharyngeal level were negatively correlated with AHI during normal respiration and Müller＇s maneuver state and were positively correlated with LSaO2;the volume of hypo-pharyngeal were negatively correlated with AHI during normal respiration;the volume of glosso-pharyngeal were positively correlated with LSaO2 during Müller＇s maneuver state.Conclusion：（1）The volume of velo-pharyngeal level with OSAHS patients can reflect the severity of AHI,LSaO2.（2）The measurement of upper airway volume using spiral computed tomography threedimensional reconstruction technique is good method to evaluate the upper airway compliance of OSAHS patients.
