To assess the oropharyngeal airway in Iranian female young adults with different skeletal patterns using cone-beam computed tomography (CBCT).
This descriptive, cross-sectional study evaluated 105 CBCT scans of female patients between 18 and 35 years retrieved from the archives of a radiology clinic. The images were evaluated in axial, sagittal, and frontal sections. In the axial plane, the maximum and minimum cross-sectional area (CSA) of the airways at the oropharynx, minimum width (anteroposteriorly), and minimum depth (laterally) were measured using Mimics Medical software. The oropharyngeal volume was measured by NemoFAB software. The values were compared among the groups with different sagittal, vertical, and transverse patterns. The correlation of indices with airway measurements was analyzed using Monte Carlo Chi-square and Pearson's correlation coefficient.
No significant difference was noted in oropharyngeal airway dimensions and volume among cases with different skeletal sagittal, vertical, and transverse patterns ( > 0.05) except for class III patients with normal transverse pattern in whom maximum CSA in low-angle group was larger than that in normal-angle group ( < 0.05) and class I normal-angle patients in whom maximum CSA in transverse normal group was smaller than that in constriction group ( < 0.05).
Oropharyngeal dimensions were not significantly different in Iranian female young adults with different skeletal patterns.
使用锥形束计算机断层扫描（CBCT）评估不同骨骼类型的伊朗年轻成年女性的口咽气道。
这项描述性横断面研究评估了从一家放射科诊所档案中检索出的105例18至35岁女性患者的CBCT扫描图像。在轴向、矢状和冠状面评估图像。在轴向平面上，使用Mimics Medical软件测量口咽部气道的最大和最小横截面积（CSA）、最小宽度（前后方向）和最小深度（左右方向）。使用NemoFAB软件测量口咽容积。比较不同矢状、垂直和横向类型组之间的值。使用蒙特卡罗卡方检验和皮尔逊相关系数分析各指标与气道测量值的相关性。
除了横向正常型的III类患者中低角组的最大CSA大于正常角组（<0.05）以及I类正常角患者中横向正常组的最大CSA小于狭窄组（<0.05）外，不同骨骼矢状、垂直和横向类型的病例在口咽气道尺寸和容积方面未观察到显著差异（>0.05）。
不同骨骼类型的伊朗年轻成年女性的口咽尺寸无显著差异。
