The aim of the current study was to evaluate the pharyngeal airway dimensions of individuals with different skeletal patterns in a cohort of the Emirati population. The specific aim was to assess the relationship between pharyngeal airway dimensions and anterior facial height in relation to different skeletal patterns. This retrospective study was conducted on a sample of 103 CBCT scans of adult Emirati subjects categorized into three groups according to their skeletal classification as indicated by the ANB angle: Class I (n = 35), Class II (n = 46), and Class III (n = 22). All CBCT scans were taken using an i-CAT CBCT imaging machine (Imaging Sciences, Hatfield, PA, USA). The age range of the patients was 19 to 68 years (62 women and 41 men). ANOVA, -tests, Kruskal-Wallis, and Mann-Whitney tests were employed for comparing means among groups. The correlation coefficient was used to evaluate the association between variables. A -value of less than 0.05 was considered statistically significant. This study revealed significant associations between various airway parameters and cephalometric measurements. Positive correlations were observed between nasal cavity volume and nasopharynx volume, as well as anterior facial height. Oropharynx volume exhibited positive correlations with hypopharynx volume and total airway volume, and negative correlations with overjet, ANB angle, and patient age. Hypopharynx volume correlated positively with total airway volume and the most constricted area of the airway (MCA). Total airway volume showed positive correlations with MCA and anterior facial height. MCA had negative correlations with ANB angle and patient age. Nasopharynx volume was significantly larger in the skeletal Class I group than in the Class II or Class III groups, while the other airway parameters showed no significant differences among the groups ( > 0.05). Several airway parameters showed a correlation with anterior facial height among the different skeletal patterns. Nasopharyngeal airway volume was significantly larger in the skeletal Class I group than in Class II and III groups in the studied sample.
本研究的目的是评估阿联酋人群队列中不同骨骼类型个体的咽部气道尺寸。具体目的是评估咽部气道尺寸与前面部高度之间的关系，以及不同骨骼类型之间的关系。本回顾性研究对103例成年阿联酋受试者的CBCT扫描样本进行，根据ANB角所示的骨骼分类将其分为三组：I类（n = 35）、II类（n = 46）和III类（n = 22）。所有CBCT扫描均使用i-CAT CBCT成像仪（美国宾夕法尼亚州哈特菲尔德市的Imaging Sciences公司）进行。患者年龄范围为19至68岁（62名女性和41名男性）。采用方差分析、t检验、Kruskal-Wallis检验和Mann-Whitney检验比较组间均值。相关系数用于评估变量之间的关联。P值小于0.05被认为具有统计学意义。本研究揭示了各种气道参数与头影测量值之间的显著关联。鼻腔容积与鼻咽容积以及前面部高度之间存在正相关。口咽容积与下咽容积和总气道容积呈正相关，与覆盖、ANB角和患者年龄呈负相关。下咽容积与总气道容积和气道最狭窄区域（MCA）呈正相关。总气道容积与MCA和前面部高度呈正相关。MCA与ANB角和患者年龄呈负相关。I类骨骼组的鼻咽容积显著大于II类或III类骨骼组，而其他气道参数在各组之间无显著差异（P>0.05）。在不同骨骼类型中，几个气道参数与前面部高度存在相关性。在所研究的样本中，I类骨骼组的鼻咽气道容积显著大于II类和III类骨骼组。
