The aim of this study was to obtain a quantitative anatomical description of the hyoid bone-larynx complex using modern 3D reconstruction tools. The study was conducted on 104 bones from CT scan images of living adult subjects. Three-dimensional reconstructions were created from CT scan images using AVIZO 6.2 software package. A study of this complex was carried out using metric and morphological analyses. Characteristics of the hyoid bone and larynx were highly heterogeneous and were closely linked with the sex, height, and weight of the individuals. Height and width of larynx were significantly greater in men than in women (24.99 vs. 17.3 mm, p ≤ 0.05 and 46.75 vs. 41.07, p ≤ 0.05), whereas the thyroid angle was larger in females (81.12° vs. 74.48°, p ≤ 0.05). There was a significant correlation between the height and weight of subjects and different measurements of the hyoid-larynx complex. (Pearson's coefficient correlation r = 0.42, p ≤ 0.05 between the height of thyroid ala and the height of subjects and r = 0.1, p ≤ 0.05 between the height of thyroid ala and the weight of subjects). Shape and size analysis of the hyoid-larynx complex showed the existence of a significant sexual dimorphism and high interindividual heterogeneity depending to patient morphology. These results encourage us to go further with functional and imaging correlations.
本研究的目的是使用现代三维重建工具获得舌骨-喉复合体的定量解剖学描述。该研究对104例成年活体受试者的CT扫描图像中的骨骼进行。使用AVIZO 6.2软件包从CT扫描图像创建三维重建。使用测量和形态学分析对该复合体进行研究。舌骨和喉的特征高度异质，并且与个体的性别、身高和体重密切相关。男性喉的高度和宽度显著大于女性（24.99对17.3毫米，p≤0.05；46.75对41.07，p≤0.05），而女性的甲状腺角更大（81.12°对74.48°，p≤0.05）。受试者的身高和体重与舌骨-喉复合体的不同测量值之间存在显著相关性。（甲状腺翼高度与受试者身高之间的Pearson相关系数r = 0.42，p≤0.05；甲状腺翼高度与受试者体重之间的r = 0.1，p≤0.05）。舌骨-喉复合体的形状和大小分析表明，存在显著的性别二态性以及取决于患者形态的高度个体间异质性。这些结果鼓励我们进一步进行功能和影像学相关性研究。
