摘　　要：目的:探讨儿童安氏Ⅰ、Ⅱ、Ⅲ类错畸形患者舌体积、舌骨位置、气道容积及颌面部形态的关系。方法:收集2015年12月—2018年12月无锡市儿童医院口腔科收治的112例错畸形患儿资料,采用安氏分类法分为Ⅰ类(42例)、Ⅱ类(38例)和Ⅲ类(32例)。利用口腔B超测量舌体积,头颅侧位片评估舌骨位置,锥形束CT(CBCT)测量气道容积和评估颌面部形态。对患儿舌体积、舌骨位置、气道容积及颌面部形态进行相关性分析。采用SPSS 20.0软件包对数据进行统计分析。结果:Ⅲ类患儿舌体积显著大于Ⅰ类和Ⅱ类(P<0.05);Ⅱ类患儿H-FH、H-MP显著大于Ⅰ类和Ⅲ类,H-VL显著小于Ⅰ类和Ⅲ类(P<0.05);Ⅲ类患儿H-FH、H-MP显著小于Ⅰ类,H-S显著大于Ⅰ类(P<0.05);3组患儿V_(喉)从小到大依次为Ⅱ类、Ⅰ类、Ⅲ类,组间差异有统计学意义(P<0.05);3组患儿V_(鼻)从小到大依次为Ⅲ类、Ⅰ类、Ⅱ类,Ⅲ类患儿V_(鼻)显著小于Ⅰ类和Ⅱ类(P<0.05);3组患儿SNB角从小到大依次为Ⅱ类、Ⅰ类、Ⅲ类,组间差异有统计学意义(P<0.05);3组患儿ANB角从小到大依次为Ⅲ类、Ⅱ类、Ⅰ类,组间差异显著(P<0.05);患儿舌体积与V_(喉)、V_(鼻)、SNB呈正相关,与H-FH、ANB呈负相关(P<0.05);H-FH和H-MP与SNB角呈负相关,与H-MP和ANB角呈正相关(P<0.05);患儿V_(鼻)与SNB角呈负相关,V_(喉)与ANB角呈负相关(P<0.05)。结论:安氏Ⅲ类错畸形患儿舌体积较大,舌骨向上移位,鼻咽容积较小。安氏Ⅱ类错畸形患儿舌体积较小,舌骨向下移位,口咽容积较小。错畸形患儿舌体积、舌骨位置、气道容积及颌面部形态具有相关性。正畸治疗时,应重视下颌骨后退对上气道形态的影响,以达到最佳的美观和治疗效果。PURPOSE:To investigate the relationships among tongue volume,hyoid position,airway volume and maxillofacial form in paediatric patients with ClassⅠ,ClassⅡand ClassⅢmalocclusion.METHODS:Data of 112 children with malocclusion in the Department of Stomatology,Wuxi Children’s Hospital from December 2015 to December2018 were collected.The children were divided into three groups according to Angle’s classification:ClassⅠ(n=42),ClassⅡ(n=38)and ClassⅢ(n=32).Tongue volume was evaluated by oral B-ultrasound,the hyoid position was obtained by lateral cephalogram,then the airway volume and maxillofacial form were evaluated by cone-beam CT(CBCT).Relationship among tongue volume,hyoid position,airway volume and maxillofacial form were analyzed.The data were processed by SPSS 20.0 software package.RESULTS:The tongue volume of Class III was significantly larger than that of Class I and Class II(P<0.05);H-FH and H-MP of Class II were significantly larger than those of Class I and Class III,and H-VL was significantly smaller than that of Class I and Class III(P<0.05).H-FH and H-MP of Class III were significantly smaller than those of Class I,and H-S was significantly larger than that of Class I(P<0.05);V throat of three types was the largest in ClassⅢ,followed by Class I and ClassⅡ,with significant difference(P<0.05).V nose of three types was the largest in ClassⅡ,followed by Class I and ClassⅢ,with significant difference(P<0.05).SNB angle of three types was the largest in ClassⅢ,followed by ClassⅠand ClassⅡ,with significant difference(P<0.05).ANB angle was the largest in Class I,followed by ClassⅡand ClassⅢ,with significant difference(P<0.05).Tongue volume was positively correlated with V throat,V nose,and SNB,and negatively correlated with H-FH and ANB(P<0.05).H-FH and H-MP were negatively correlated with SNB angle and positively correlated with H-MP and ANB angle(P<0.05).CONCLUSIONS:Children with ClassⅢmalocclusion have larger tongue volume,upward displacement of hyoid,and smaller nasopharyng
