摘要

背景通过了解骨结构在口面部系统中的最佳位置及其与颅底和颌底的关系,可以及时识别错颌的发展。本研究的目的是评估颅底、下颌骨和舌骨在不同的前后骨错颌中的关系。材料和方法本回顾性研究评估了120张年龄在15至30岁之间的个体侧位头颅x线片。根据垂直于A点的N和垂直于b点的N,采用Burstone的分析方法将受试者分为三组。使用Nemoceph v.12软件(Nemotec, Spain)分析所收集个体的侧位脑电图。测量鼻-鞍-关节(NSAr)、舌骨角(C3HyD)、鞍-关节-舌骨角(SArHy)和鼻-鞍-舌骨角(NSHy),并进行比较。结果在本研究中,考虑到三个研究组的角度不同,SArHy角度差异有统计学意义(p <0.05)。然而,鞍角(NSAr)和舌骨角(C3HyD)在三个研究组之间无统计学差异。采用事后Bonferroni检验比较两组间的差异。统计学上有显著差异(p <I类组与II类组、II类组与III类组间差异均为0.05)。虽然本研究的结果表明,三组之间鞍角没有变化,但SArHy角在I类、II类和III类骨骼关系中的显著相关性表明,舌骨位置在各种骨骼模式中都有适应。我们还认为舌骨的后位与骨骼II类错颌有关,而舌骨的前位与骨骼III类错颌有关。

Correlation between Cranial Base, Mandible, and Hyoid Bone Position in Different Anteroposterior Skeletal Malocclusions: A Cephalometric Study
Abstract Background Development of malocclusion can be promptly recognized through an understanding of the optimal position of the bone structures in the orofacial system and their relationship to the cranial base and jaw base. The aim of this study was to assess the relationship between the cranial base, mandible, and hyoid bone in different anteroposterior skeletal malocclusions. Materials and Methods This retrospective study evaluated 120 lateral cephalometric radiographs of individuals aged between 15 and 30 years. The subjects were classified using Burstone's analysis into three groups based on the N perpendicular to point A and N perpendicular to point B. The collected lateral cephalograms of the selected individuals were analyzed using Nemoceph v.12 software (Nemotec, Spain). The nasion-sella-articulare (NSAr), hyoidale angle (C3HyD), sella-articulare-hyoid angle (SArHy), and nasion-sella-hyoid (NSHy) angles were measured and compared among all the three groups. Results In the present study, considering the various angles among the three study groups, a statistically significant difference was observed for the SArHy angle (p < 0.05). However, the saddle angle (NSAr) and hyoidale angle (C3HyD) showed no statistically significant difference between the three study groups. Post hoc Bonferroni test was applied to compare the differences between two groups. A statistically significant difference (p < 0.05) was observed between class I and class II and between class II and class III groups. Conclusion Though the findings of the present study concluded that there is no variation in saddle angle among the three groups, the significant association of SArHy angle among class I, class II, and class III skeletal relationships, suggests an adaptation of the hyoid bone position in various skeletal patterns. We also suggest that the posterior positioning of the hyoid bone is related to skeletal class II malocclusion, whereas a forward positioning of the hyoid bone is related to skeletal class III malocclusion.
