背景：锥形束 CT 在口腔颅颌面部的应用越来越广泛，明确正常人群的舌骨位置对于判断正畸治疗前后舌骨的位置变化和对上气道的影响有重要意义。目的：确定山东地区6-19岁正常骨面型的儿童青少年舌骨位置的锥形束CT测量值范围，为当地儿童青少年正畸治疗前后舌骨位置的改变程度提供参考依据。方法：对254例(男120例，女134例)山东地区正常骨面型的6-19岁人群的锥形束CT图像进行分析，应用Mimics 10.01软件在最大矢状面上对舌骨位置进行线性和角度测量，确定舌骨位置指标的正常值范围和95%置信区间，并通过独立样本t 检验分析其性别差异。结果与结论：得出山东地区正常骨面型6-19岁人群舌骨位置相对于颅底、上、下颌骨和颈椎的正常值范围及男女间差异比较，得出14-15岁、16-17岁、18-19岁人群的部分舌骨位置测量项目存在着性别差异(P <0.05)。结果表明，从12-13岁起，舌骨相对于颅底的垂直位置在男性要低于女性，舌骨相对于上颌骨的位置也得到类似结论。舌骨相对于颈椎的水平位置则在14-15岁和18-19岁表现出男性比女性更靠前方。

BACKGROUND:With the extensive application of cone-beam CT in oral and craniofacial surgery, a clear hyoid bone position indicator for normal population has important implications for the change of hyoid bone position before and after orthodontics. OBJECTIVE:To determine the cone-beam CT measurement range of hyoid bone position in populations aged 6-19 years from Shandong, so as to provide a reference marker for the change of hyoid bone position before and after orthodontics in local children and adolescents. METHODS:Totaly 254 healthy children (120 males and 134 females) aged 6-19 years from Shandong Province were subjected to cone-beam CT scan of the hyoid bone. Mimics10.01 was used to evaluate the linear and angular measurements of hyoid bone position, and then the normal value range was confirmed. Independent-samplet-test was used for analysis of gender difference and 95% confidence interval was calculated. RESULTS AND CONCLUSION: There were gender differences in a part of indicators of hyoid bone position among 14-15 years, 16-17 years, 18-19 years groups (P < 0.05). For children aged 12-13 years, the hyoid bone position vertical to the base of skul and upper jaw bone is lower in males than in females. For children aged 14-15 years and 18-19 years, the hyoid bone horizontal to the cervical spine is more forward in males than in females.
