目的:探讨可调式口腔矫治器治疗儿童阻塞性睡眠呼吸暂停综合征(OSAS),下颌前伸时上气道及周围结构的变化及其规律。方法:对32例戴用可调式口腔矫治器治疗有效的OSAS患儿,进行治疗前后X线头影测量分析。结果:32例OSAS患儿,AH-MP距减少30.70%,AH-Ge距减少10.38%,AH-CVP距增加4.95%,AH-FH距减少4.26%,V-T减少5.32%,SPP-SPPW距增加27.04%,U-MPW距增加17.10%,TB-TPPW增加20.68%,V-LPW距增加18.28%,LPW-CVP减少13.43%,V-Ge距增加18.27%,均有统计学意义。结论:X线头影测量用于治疗儿童OSAS的辅助诊断、治疗及疗效评价具有重要价值。
Objective: To investigate the changes and regularities of adjustable oral appliance in the treatment of obstructive sleep apnea syndrome (OSAS), upper airway and its surrounding structures in mandibular protraction. Methods: 32 cases of children with OSAS who were treated with adjustable oral appliance were treated with X-ray cephalometry before and after treatment. Results: In 32 OSAS children, the AH-MP distance was reduced by 30.70%, AH-Ge distance was reduced by 10.38%, AH-CVP distance was increased by 4.95%, AH-FH distance was decreased by 4.26%, VT was decreased by 5.32% 27.04%, U-MPW distance increased 17.10%, TB-TPPW increased 20.68%, V-LPW distance increased 18.28%, LPW-CVP decreased 13.43%, V-Ge distance increased 18.27%, both were statistically significant. Conclusion: X-cephaplex measurement is of great value in the diagnosis, treatment and evaluation of the therapeutic effect of OSAS in children.
