摘　　要：目的研究青少年Ⅰ类磨牙关系的口呼吸患者矫治后上气道结构及睡眠通气情况改变。方法根据纳入和排除标准,在正畸初诊患者中筛选出22例口呼吸患者,选择不同的矫治方式进行矫治,测量矫治前后X线头影侧位片上气道矢状结构骨性鼻咽段、腭咽段、舌咽段、喉咽段的变化及睡眠呼吸指数的改变,采用SPSS19.0统计软件进行矫治前后样本配对检验。结果矫治后,骨性鼻咽(PNS-Ba)、中腭咽段的软腭后与软腭后咽壁点连线距离(SPP-SPPW)均增宽且有统计学意义(P<0.05)。舌骨水平位置(H-CVP)增宽,CL(UC-LC)(软腭与舌重叠长度)、软腭上后气道间隙(PNS-R)轻度缩窄,但均无显著性差异。AHI下降,平均SPO2及最低SPO2均上升(P<0.05)。结论Ⅰ类磨牙关系的口呼吸患者矫治后上气道鼻咽段和腭咽段不同程度增宽,睡眠呼吸通气好转。Objective To investigate the changes of upper airway structure and sleep-breathing parameters in teenagers with Class Ⅰ molar relationship after orthodontic treatment. Methods Different orthodontic treatments were selected for 22 cases with Class Ⅰ molar relationship and mouth-breathing; the changes of upper airway structure in the leteral cephalometric radiographs were measured and the changes of sleep-breathing parameters were recorded; a statistical analysis was made with the software SPSS19.0. Results After treatments, PNS-Ba and SPP-SPPW increased （P〈0.05）; H-CVP increased （P〉0.05）; CL （UC-LC）, PNS-R decreased slightly （P〉0.05）; AHI decreased; AveO2 and MiniO： increased （P〈0.05）. Conclusions The orthodontic treatment leads to the increase of the nasopharynx and pharyngeal segment of upper airway and the improvement of sleep respiratory ventilation in teenagers with Class Ⅰ molar relationship and mouth-breathing.
