Abstract
OBJECTIVE
To correlate the pharyngeal airway subregions with the positioning of the hyoid bone.
MATERIAL AND METHODS
The study examined 107 lateral cephalometric (LC) and cone beam computed tomography (CBCT) images. Linear and volumetric measurements of the pharyngeal subregions were made and correlated to linear measurements using hyoid triangle analysis on images of LC and multiplanar (MPR) and three-dimensional (3D) reconstructions of CBCT.
RESULTS
There was significant correlation between linear measurements of the pharyngeal subregions and hyoid bone position in LC images and in MPR and 3D reconstructions of the CBCT. Correlations were more frequent in the oropharynx and hypopharynx, especially for LC images. No correlations were observed between LC images or CBCT reconstructions and the volumetric measurements of the pharyngeal subregions and the position of the hyoid bone.
CONCLUSION
The hyoid bone position showed more correlations with oropharynx and hypopharynx airway measurements. The hyoid triangle method was not applicable to 3D images, since it showed a smaller number of measures correlated to the hyoid bone position.
摘要
目的
探讨咽腔各亚区与舌骨位置的相关性。
材料与方法
研究纳入了 107 例侧位头颅定位片（LC）和锥形束 CT（CBCT）图像。对咽腔各亚区进行线性和容积测量，并通过 LC 图像上的舌骨三角分析，以及 CBCT 的多平面重建（MPR）和三维（3D）重建图像进行线性测量的相关性分析。
结果
LC 图像及 MPR 和 3D 重建 CBCT 图像中咽腔各亚区的线性测量值与舌骨位置呈显著相关性。在口咽和下咽，相关性更为常见，尤其是 LC 图像。LC 图像或 CBCT 重建图像与咽腔各亚区的容积测量值和舌骨位置之间无相关性。
结论
舌骨位置与口咽和下咽气道测量值的相关性更高。由于与舌骨位置相关的测量值较少，舌骨三角方法不适用于 3D 图像。
