目的 探讨影响儿童上气道大小的影响因素.方法 50例7至13岁儿童,男20例,女30例,上颌发育由正常至不足(SNA 79.85°±3.49°),下颌发育从正常至不同程度的发育过度(SNB 81.55°±3.71°).进行常规锥体束CT扫描,使用Dolphin软件完成41项牙、(牙合)、颌、面头影测量指标,完成上气道及其各区段的高度、截面积和体积测量.对上气道各项指标与患儿一般发育指标、头影测量各项指标进行相关分析.结果 年龄是上气道重要影响因素(r=0.417,P=0.020);颌骨硬组织指标Pg-NB、Co-Gn、Ar-Go、SGo,牙性指标U1-NA、L1-MP、OB对上气道大小的影响有统计学意义.结论 骨性指标与牙性指标均对上气道大小有影响,生长发育主要通过垂直向发育影响儿童上气道大小.

Objective To explore potential influence factors on the dimensions of the upper airway in children.Methods 50 children aged from 7 to 13 years old (20 males,30 females) were selected.Their maxillary development were between normal to deficienct (SNA 79.85±3.49°),while the development of mandible ranged from normal to overdue (SNB 81.55 ± 3.71°).All children underwent CBCT scan and their 41 dental,occlusal,jaw and facial cephalometric variables were measured with Dolphin Software to evaluate the height,sectional area and corresponding volume in 3 parts of upper airway.Correlated analysis was done both between upper airway variables and general development variables,and upper airway variables and cephalometric variables.Results Age is an important influence factor (r=0.417,P =0.020).Skeletal measurements of Pg-NB,Co-Gn,Ar-Go and Sgo showed statistical significance on the upper airway.So did dental measurements of U1-NA,L1-MP and OB.Conclusions The dimensions of the upper airway were influenced by skeletal and dental structures.The effect of growth on the upper airway were mainly from its role in vertical dimension.
