目的：观察改良双合垫矫治器（TBA）治疗儿童阻塞性睡眠呼吸暂停低通气综合征（OSAHS）的疗效及气道变化。方法下颌骨后缩合并OSAHS患儿25例，用改良TBA治疗，治疗前后采用多导睡眠监测血氧饱和度（SaO2）、睡眠呼吸暂停低通气指数（AHI），并通过锥体束CT（CBCT）三维重建分析上气道大小形态的改变。结果治疗后V总-口咽气道总体积、Amin-气道最小截面面积、L矢-最小截面矢状径、L横-最小截面横径、L矢/L横-最小截面矢状径/横径、SaO 2均明显大于治疗前（ P＜0．05）， AHI明显低于治疗前（ P＜0．05）。结论下颌后缩合并OSAHS儿童，采用改良式TBA治疗后，气道矢状、横向宽度增加，明显改善通气。

Objective To observe the effect of improved twin-block applicance(TBA) on the treatment of obstructive sleep apnea hypopnea syndrome ( OSAHS ) and airway changes in children .Methods Twenty-five OSAHS children with mandibular deficiency were treated with improved TBA .Oxygen saturation ( SaO2 ) ,apnea-hypopnea index ( AHI) were monitored by polysomnography before and after treatment .Three-dimensional cone beam computed tomography ( CBCT) reconstruction was used to analyze the morphological changes of the upper airway .Results After treatment, the patients′volume and area of the upper airway increased significantly (P<0.05),SaO2 increased but AHI reduced (P<0.05).Conclusion The improved TBA applied to treatment of OSAHS children with mandibular deficiency can increase the shape and size of the airway and improve the airway ventilation effectively .
