This study investigated the association between tongue and hyoid position, tongue volume, and pharyngeal airway dimensions with craniofacial growth patterns in the sagittal, vertical, and transverse planes.
Cone beam computed tomography was used to assess 185 non-growing subjects (mean age, 28.7 ± 9.5 years). Multivariate linear regression analyses evaluated relationships between tongue and airway variables, and cephalometric/dental arch measurements.
Class III skeletal patterns-reflected by lower ANB and higher APDI-were significantly correlated with anteriorly positioned hyoids (ANB: β = 0.249; APDI: β = -0.291), and lower tongue positions at the tongue tip (ANB: β = -0.231; APDI: β = 0.166) and in the posterior area (ANB: β = -0.186; APDI: β = 0.196), and greater tongue volume (APDI: β = 0.174). Hyperdivergent vertical patterns-indicated by a lower ODI-were significantly correlated with a lower tongue tip position (β = -0.311) and posterior tongue position (β = -0.230). Regarding transverse dimensions, tongue volume showed positive correlations with upper intermolar width (β = 0.349), lower intercanine width (β = 0.130), lower intermolar width (β = 0.311), and a negative correlation with upper intercanine width (β = -0.299).
Sagittal and vertical craniofacial patterns are interrelated and show associations with tongue and hyoid position, as well as tongue volume. Transverse dental arch dimensions are correlated not only with tongue position and volume but also with pharyngeal airway volume.
本研究调查了舌与舌骨位置、舌体积以及咽气道尺寸与矢状面、垂直面和横断面颅面生长模式之间的关联。
采用锥形束计算机断层扫描评估185名非生长发育期受试者（平均年龄28.7±9.5岁）。多变量线性回归分析评估舌与气道变量以及头影测量/牙弓测量之间的关系。
由较低的ANB和较高的APDI反映的III类骨骼模式与舌骨向前位置（ANB：β = 0.249；APDI：β = -0.291）、舌尖较低位置（ANB：β = -0.231；APDI：β = 0.166）和后部区域较低位置（ANB：β = -0.186；APDI：β = 0.196）以及更大的舌体积（APDI：β = 0.174）显著相关。由较低的ODI表明的高角垂直模式与较低的舌尖位置（β = -0.311）和舌后部位置（β = -0.230）显著相关。关于横断面尺寸，舌体积与上颌磨牙间宽度（β = 0.349）、下颌尖牙间宽度（β = 0.130）、下颌磨牙间宽度（β = 0.311）呈正相关，与上颌尖牙间宽度呈负相关（β = -0.299）。
矢状面和垂直面颅面模式相互关联，并与舌和舌骨位置以及舌体积相关。横断面牙弓尺寸不仅与舌位置和体积相关，还与咽气道体积相关。
