舌根会厌关系分型对阻塞性睡眠呼吸暂停低通气综合征患者舌后区呼吸道狭窄的预测意义

The relationship of lingual region upper airway stricture and lingua-epiglottis position type in obstructive sleep apnea hypopnea patients

目的研究阻塞性睡眠呼吸暂停低通气综合征(obstructive sleep apnea hypopnea syndrome,OSAHS)患者舌根会厌关系分型与舌后区上呼吸道狭窄的关系。方法经多导睡眠监测系统(Polysomnography,PSG)确诊的OSAHS患者1 1 3例,采用螺旋CT对上呼吸道进行连续扫描,对舌后区呼吸道各参数进行测量,对比研究不同舌根会厌关系分型组间舌后区呼吸道各测量参数与舌后区呼吸道狭窄发生率的差别。结果不同舌根会厌关系分型的OSAHS患者的一般临床资料无明显差别,舌根会厌关系从Ⅰ型到Ⅲ型,舌后区呼吸道截面积和内径逐渐缩小,舌体长度和舌截面积逐渐增加,舌后区呼吸道狭窄的发生率逐渐增高。结论舌根会厌关系分型与舌后区呼吸道狭窄有明显相关,临床可以通过对舌根会厌关系分型的观察来初步判断舌后区呼吸道状态。

Objective To investigate the relationship of lingual region upper airway stricture and lingua-epiglottis position type in OSAHS patients.Methods 113 patients with OSAHS were divided into three groups by lingua-epiglottis position type.The dimensions and area of lingual region airway,the thickness of retropharyngeal and lateral pharyngeal tissue,the tongue width,tongue lengoth and tongue area were compared among each groups.Results No difference on age,BMI,AHI and lowest pulse oxygen was found among three groups of OSAHS patients.CT comparative results of the three groups showed the area,coronal and airway diameter of lingual region upper airways were diminishing,tongue length,tongue area and the percentage of lingual region airway stricture were increasing from type Ⅰ to type Ⅲ.Conclusion The study suggests there is an evident correlation between lingual region airway stricture and lingua-epiglottis position type in OSAHS patients.Lingual region airway stricture can be predicted by lingua-epiglottis position type.
