Results ①Of 82% OSAHS patients' sleep indices were normal after the oral appliance therapy;②Compared to the control group,the patients with OSAHS had narrower upper-posterior airway volume and shorter distance from tip of the uvula to the posterior pharyngeal wall and lower positioned hyoid bone and shorter tongue before treatment;③Compared to before treatment,the OSAHS patients after therapy had lower positioned and shorter and flatter tongue,the upper hyoid bone,more anterior and downward mandibular and wider upper-posterior airway volume.

结果 ①82%患者治疗后睡眠指标达正常标准；②与配对组相比OSAHS患者上气道后间隙及悬雍垂尖至咽后壁距较窄，舌骨至下颌平面距较大，舌较短；③戴入口腔矫治器后患者舌体下降，舌变短而平坦，舌骨上移，下颌骨前下方移位，上气道后间隙扩大，与配对组比较，除舌体下移外其它测量项目值差异无显著性。
