摘　　要：目的通过头颅侧位片分析低角型错[牙合]畸形与颈椎骨骼异常之间是否存在关联,统计低角病例颈椎异常的发病率,分析颈椎形态与头颈姿势和颅面形态间的关系。方法选取2011—2019年就诊于哈尔滨医科大学口腔医院正畸科的60例低角病例作为试验组。另随机选取60例均角病例作为对照组。所有病例年龄范围16~40岁。记录前4个颈椎融合和后弓发育缺陷的数据,统计颈椎异常各亚类的发生情况,并分析颅面颈部各测量项目与颈椎异常的相关性。结果低角组颈椎融合患病率56.7%,均角组21.7%,颈椎融合多发生在第二和第三颈椎间,两组间比较差异有统计学意义。两组间后弓缺陷患病率无统计学差异。颅面颈部各测量值中ML/OPT、ML/CVT、SNB、NSL/ML、FH/ML、NSL/NL、NL/ML、S-Go、N-Me、ANS-Me、面高比(S-Go/N-Me)两组间比较有统计学意义。Logistic回归分析显示:颈椎融合的发生与FH/ML有相关性。结论低角病例颈椎融合的发生率明显增加,说明颈椎融合的发生可能与面部垂直向生长方式相关。Objective To analyze whether there is a relationship between the low angle malocclusion and cervical abnormalities with the lateral cephalometric radiographs,to statistically analyze the incidence of cervical vertebra abnormalities in low angle cases and the relationship between cervical morphology and neck posture and craniofacial morphology.Methods Sixty low angle cases diagnosed in Department of Orthodontics in Harbin Medical University in 2011-2019 were selected as experimental groups.Another 60 cases of average angle were randomly selected as the control group.All patients ranged from 16 to 40 years old.The data of the first 4 cervical fusions and posterior arch deficiency were recorded.The incidence of cervical anomalies was counted.And the correlation between the measurement of the craniofacial neck and cervical abnormalities was analyzed.Results The prevalence of cervical fusion in the low angle group was 56.7%,and that of the average angle group was 21.7%.Cervical fusion occurred mostly in the second and third cervical vertebrae.The difference between the two groups was statistically significant.There was no significant difference in the posterior arch deficiency.ML/OPT,ML/CVT,SNB,NSL/ML,FH/ML,NSL/NL,NL/ML,S-Go,N-Me,ANS-Me,S-Go/N-Me in the measurements of craniofacial were statistically significant between the two groups.Logistic regression analysis showed that the occurrence of cervical fusion was related to FH/ML.Conclusion The incidence of cervical fusion in low angle patients is significantly increased,indicating that the occurrence of cervical fusion may be related to the vertical growth pattern of the face.
