摘　　要：目的通过头颅侧位片研究正畸-正颌联合治疗的骨性Ⅲ类错畸形与颈椎骨骼异常之间是否存在关联。方法选取正畸-正颌联合治疗的安氏Ⅲ类实验组患者249名,其中男性120名,女性129名。无明显牙颌畸形的安氏Ⅰ类对照组250名,其中男性85名,女性165名,所有患者年龄范围18~36岁。头颅侧位片记录前4个颈椎融合和后弓缺陷的数据。正畸-正颌联合治疗的骨性Ⅲ类错畸形与颈椎骨骼异常之间的关系采用卡方检验进行分析。结果实验组的颈椎融合发生率为50.2%,而对照组仅为13.2%,实验组显著高于对照组(P<0.001);实验组的寰椎后弓缺陷的发生率为4.8%,而对照组为2.8%,卡方检验显示两组间比较差异有统计学意义(P<0.05);实验组中有3.2%既有颈椎融合又有后弓缺陷,而对照组为1.2%,两组比较差异无统计学意义(P>0.05)。结论正畸-正颌联合治疗的骨性Ⅲ类错畸形患者颈椎骨骼异常的发生率明显增加。Objective To investigate whether there is an association between skeletal Class Ⅲ and the cervical skeletal abnormalities corrected by combined orthodontic and orthognathic treatment via lateral cephalometric. Methods 249 patients with skeletal Class Ⅲ,who had accepted orthodontic-orthognathic surgery,were selected as the experimental group,120 male and 129 female; 250 patients with Class Ⅰ,who had only accepted orthodontic treatment,were selected as the control group,85 male and 165 female. All the patients＇ ages were between 18 - 36. The data of the first four cervical fusion and posterior arch defects were recorded by the lateral cephalometric. The relationship between the abnormal cervical vertebra and skeletal Class Ⅲ corrected by combined orthodontic and orthognathic treatment was analyzed by chi-square test. Results The occurrence rate of the cervical fusion in the experimental group was50.2%,while in the control group it was 13.2%.The occurrence rate in the experimental group was significantly higher than that of the control group（ P〈0.001）. The occurrence rate of the posterior arch defects in the experimental group was 4. 8%,while in the control group it was 2.8% and chi-square test showed that there was statistical significance between the two groups（ P〈0.05）. The occurrence rate of both cervical fusion and posterior arch defects was 3.2% in the experimental group,while in the control group it was 1.2%,and there was no statistical significance between the two groups（ P〈0.05）. Conclusion There is an obviously increasing occurrence rate of the cervical skeletal abnormalities in patients with skeletal Class Ⅲ corrected by combined orthodontic and orthognathic treatment.
