The relationship among the orofacial system and the rest of the body ,both in functional and anatomical terms was the subject of numerous scientific studies. The optimum position of the bone structures of orofacial system provides performance of intact vital functions, such as breathing or swallowing. Hyoid bone represents a link between the head and neck. Although located in the neck, hyoid bone due to its brachial origin belongs to the visceral skeleton.
a) To determine the position of the hyoid bone, in relation to the cranial base, mandible and cervical part of the vertebra; b) To determine the linear measures of hyoid bone and its constituents and c) to Identify on the profile teleroengen image, whether there are differences in the position of hyoid bone depending on the saggital maxillo-mandibular relationship.
30 profile teleroengen images of patients aged 17-18 years of both sexes were used for this study. To study the position of hyoid bone depending on the saggital maxillo-mandibular relationship respondents were divided into groups based on the ANB-angle values. The first group is ortognat patients with ANBangle values, from 1 to 4°. The second group included patients with distal jaw relationship, that is, whose values of ANB-angle were greater than / or 5°. The third group consists of patients with ANB-angle value of 0 or negative.
The position of hyoid bone is not constant, but depends on the maxillo-mandibular anterior posterior relationships. Length of hyoid bones and greater horns of hyoid bone differs with respect to the sagittal malocclusion. In relation to the cranial base and maxillary bones flat position of the hyoid bone is highly correlated. A positive correlation was found with relation to the cervical vertebra, while the dependence is determined in relation to the steep mandibular plane.
口腔颌面系统与身体其他部位在功能和解剖学方面的关系是众多科学研究的主题。口腔颌面系统骨骼结构的最佳位置有助于实现完整的重要功能，如呼吸或吞咽。舌骨是头颈部之间的连接结构。尽管舌骨位于颈部，但其起源于鳃弓，属于内脏骨骼。
a）确定舌骨相对于颅底、下颌骨和颈椎的位置；b）确定舌骨及其组成部分的线性测量值；c）在侧位远距X线影像上识别舌骨位置是否因矢状位上颌-下颌关系的不同而存在差异。
本研究使用了30例17 - 18岁男女患者的侧位远距X线影像。为研究舌骨位置与矢状位上颌-下颌关系的相关性，根据ANB角值将受试者分为几组。第一组是ANB角值为1至4°的安氏Ⅰ类患者。第二组包括下颌远中关系的患者，即ANB角值大于或等于5°的患者。第三组由ANB角值为0或负值的患者组成。
舌骨的位置并非固定不变，而是取决于上颌-下颌前后关系。舌骨的长度和舌骨大角在矢状位错牙合方面存在差异。舌骨相对于颅底和上颌骨的扁平位置高度相关。与颈椎存在正相关，而与陡峭的下颌平面存在相关性。
