摘　　要：目的:探讨应用Twin-Block(TB)矫治下颌后缩伴上牙弓狭窄的安氏Ⅱ类1分类的青少年患者前后上气道矢状向宽度及舌骨位置的变化。方法:选择符合标准的青少年患者22例,使用TB矫治10~12个月,比较矫治前后上气道矢状向宽度与舌骨位置的变化。结果:与矫治前相比,矫治后患者的软腭后-软腭后咽壁距(SPP-SPPW)、悬雍垂尖-中咽壁距(U-MPW)、后气道间隙(PAS,TB-TPPW)和会厌谷-下咽壁距(V-LPW)明显增加,差异有统计学意义(P<0.05);舌骨-颏后点距(H-RGn)增加、舌骨-眶下点的水平距[H-Or(hor)]减小,差异有统计学意义(P<0.05)。结论:使用TB治疗安氏Ⅱ类1分类的青少年患者时,在口咽部及喉咽部矢状向气道可发生显著扩张,舌骨可有明显前移。Objective To explore the changes of upper airway width and hyoid bone position before and after the application of Twin-Block(TB)to correct ClassⅡDivision 1 adolescent patients with mandibular retraction and upper arch stenosis.Methods Twenty-two adolescent patients who met the criteria were selected and treated with TB combined with palatal expander for 10-12 months,and the changes of the upper airway and hyoid bone before and after the treatment were compared.Results Compared with before correction,SPP-SPPW,U-MPW,PAS(TB-TPPW)and V-LPW increased significantly,the difference was statistically significant(P<0.05).H-RGn increased,and H-Or(hor)decreased,the difference was statistically significant(P<0.05).Conclusion When using TB to treat adolescents in ClassⅡDivision 1,the airway at the level of the oropharynx and laryngopharyngeal can be significantly expanded;the hyoid bone can be significantly moved forward.
