摘　　要：目的通过锥形束CT(CBCT)探讨不同矢状骨面型错畸形儿童上颌骨与颧骨宽度、突度的差异,分析上颌骨与颧骨之间的相关性,及上颌骨和颧骨形态对于面部美观的意义。方法回顾性分析2023年5月至2024年8月于新疆医科大学第一附属医院行CBCT及头颅侧位片检查的135例错畸形儿童颧骨及上颌骨的相关影像学指标,包括鼻颧角(fmo-nfmo)、颧上颌角(zm-ss-zm)、面宽(Za-Za)、颧突点-耳点径(mp-po)、颧颌缝点-乳突点径(zm-ms)、上颌第一磨牙区、第一、第二前磨牙区基骨宽度及牙槽骨宽度(MBW、MAW、PBW、PAW、SPBW、SPAW)、前颌间距离(AIMD)、后颧间距离(PIZD)、后颞间距离(PITD),比较骨性Ⅰ、Ⅱ、Ⅲ类矢状骨面型患者CBCT影像学参数差异及颧骨和上颌骨之间的相关性,并分析面中部骨骼发育对于面部形态的意义。结果(1)MBW在骨性Ⅲ类显著小于骨性Ⅰ、Ⅱ类(P<0.05),MAW、SPBW、SPAW、PBW、PAW在三组间差异均无统计学意义(P>0.05);(2)Za-Za、AIMD、PIZD及PITD在骨性Ⅲ类显著小于骨性Ⅰ、Ⅱ类(P<0.05);(3)zm-ss-zm、mp-po和zm-ms在骨性Ⅲ类显著小于骨性Ⅰ、Ⅱ类(P<0.05),fmo-n-fmo在三组间差异均无统计学意义(P>0.05);(4)Za-Za、PIZD、PITD与MBW、MAW、SPBW、SPAW、PBW、PAW均呈显著正相关关系(P<0.05);(5)zm-ss-zm与fmo-n-fmo呈正相关关系(P<0.01),zm-ms与mp-po呈正相关关系(P<0.01)。结论骨性Ⅲ类患者的上颌基骨和颧骨在水平向和矢状向的生长量较骨性Ⅰ、Ⅱ类小,面部更显平坦甚至凹陷;上颌骨与颧骨的宽度、突度之间有相关性。Objective To investigate the differences in maxillary and zygomatic bone width and protuberance in children with different sagittal facet deformities by cone beam CT(CBCT),and to analyze the correlation between maxilla and zygomatic bone,as well as the signifificance of maxillary and zygomatic bone morphology for facial aesthetics.Methods We retrospectively analyzed the relevant imaging indexes of the zygomatic bone and maxilla in 135 children with malocclusion who underwent CBCT and lateral cephalometric films,including the nasozygomatic angle(fmo-n-fmo),zygomaticomandibular angle(zm-ss-zm),facial width(Za-Za),zygomatic point-auricular point(mp-po),zygomatico-mandibular suture point-papillary point(zm-ms),basal bone width and protuberance in the fifirst molar region of the maxilla,fifirst and second premolar region,and the maxillary bone width,and the maxillary bone shape for facial aesthetics.and second premolar regions,basal bone width and alveolar bone width(MBW,MAW,PBW,PAW,SPBW,SPAW),anterior intermandibular distance(AIMD),posterior zygomatico-intermandibular distance(PIZD),and posterior intertemporal distance(PITD),in order to compare the differences in CBCT imaging parameters between patients with bonyⅠ,Ⅱ,andⅢsagittal facial features,and the correlation between zygomatic bones and the maxilla,and analyze the signifificance of the central bone development for the shape of the face.We also analyzed the signifificance of the development of the middle bone for facial morphology.Results(1)MBW was signifificantly smaller than bone classⅢin bone classⅠandⅡ(P<0.05),and MAW,SPBW,SPAW,PBW,and PAW did not show statistically signifificant differences among the three groups(P>0.05);(2)Za-Za,AIMD,PIZD,and PITD were signifificantly smaller than bone classⅠandⅡin bone classⅢ(P<0.05);(3)zm-ss-zm,mp-po and zm-ms were signifificantly smaller than bone classⅠandⅡin bone classⅢ(P<0.05),and fmo-n-fmo had no statistically signifificant difference among the three groups(P>0.05);(4)Za-Za,PIZD and PITD showe
