摘要: 目的: 研究生长发育高峰期Ⅱ类高角错畸形患者矫形治疗前、后上气道的变化。方法: 收集并拍摄23例生长发育高峰期患者经高位头帽-口外弓肌激动器矫形治疗前(T1)、矫形治疗后(T2)的锥形束CT(CBCT),将T1和T2的CBCT数据导入Minics17.0软件中进行测量。采用SPSS22.0软件包中的配对t检验对安氏Ⅱ类儿童患者矫形治疗前、后上气道的变化进行分析。结果: 患者经矫形治疗后,上气道总容积、腭咽容积、喉咽容积、舌咽容积,软腭尖平面、会厌尖平面上气道的横截面积和口咽段最小横截面积,软腭尖、会厌尖平面的矢状径、横径的变化均具有统计学意义(P<0.05);上气道形态在软腭尖平面趋于圆形(P<0.05),而在会厌顶平面无显著变化(P>0.05)。结论: 高位头帽-口外弓肌激动器矫形治疗使下颌骨发育不足的高角儿童患者上气道容积增大,通气量增加,呼吸功能改善。

Abstract: PURPOSE: This study was performed to investigate the changes of upper airway before and after functional correction in ClassⅡmalocclusion children with high mandibular plane angle at growth and development peak. METHODS: Cone-beam CT (CBCT) data of the upper airway were inputted into Minics 17.0 software for measurement of changes in the upper airway before and after functional treatment by high headgear-activator. The changes of upper airway before and after treatment were analyzed with SPSS22.0 software package. RESULTS: The change of the total volume of the upper airway, the volume of the velopharynx, glossopharynx, laryngopharynx; the sectional area of the tip of soft palate, roof of the epiglottis, the minimum sectional area of the oropharynx were significant (P<0.05). The upper airway morphology tended to be circular in the soft palate tip plane(P<0.05), but there was no significant difference in the plane of epiglottis(P>0.05). CONCLUSIONS: High headgear-activator corrected mandibular hypoplasia in children with increased airway volume, increased ventilation, improved respiratory function to prevent occurrence of obstructive sleep apnea hypopnea syndrome after adult.
