目的研究正常儿童头位与颅面结构的相关性。方法选取33例正常儿童拍摄自然头位时的头颅侧位片,对其颅面结构、颈椎姿势及头位进行分析。结果正常儿童的SN-VEL、SN-OPT、SN-CVT与SNA、SNB、SND、SNPo存在显著负相关,与SN-GoGn、SN-PP、SN-OP、NSGn等变量存在显著正相关。结论正常儿童头位变量与一些颅面结构变量间存在显著的相关关系,尤其是与代表面部生长趋势和下颌骨生长方向的若干变量显著相关。 Objective To study the correlation between head position and craniofacial structure in normal children. Methods 33 cases of normal  children taking natural head position of the cephalometric slice, the craniofacial structure, cervical posture and head position were analyzed. Results There was a significant negative correlation between SN-VEL, SNP-OPT, SN-CVT and SNA, SNB, SND and SNPo in normal children and positive correlation with SN-GoGn, SN-PP, SN-OP and NSGn. Conclusion There is a significant correlation between head position variables and some craniofacial structural variables in normal children, especially those variables that represent facial growth tendency and mandibular growth direction.
