The present study aimed to determine the correlation between pharyngeal airway volume and craniofacial morphology through cone-beam computed tomography (CBCT). Additionally, the study analyzed the influence of gender on pharyngeal airway volume. (2) Methods: 80 CBCT scans of 40 male and 40 female patients (mean age: 15.38 + 1.10 years) fulfilling the eligibility criteria were included. CBCT scans were evaluated for pharyngeal airway volume using the In Vivo Dental 5.1 software. Additionally, CBCT-derived lateral cephalograms were used to assess various craniofacial morphology parameters. To examine the influences of gender on airway volume, T-test was carried out. Correlation between airway volume and craniofacial parameters were measured using Pearson correlation followed by regression analysis. The value of < 0.05 was considered statistically significant.
The mean airway volume was significantly greater in males than in females. A statistically significant negative correlation was found between maxillary plane inclination and pharyngeal airway volume. In contrast, a positive correlation was observed between mandibular length and lower molar inclination with oropharyngeal and total pharyngeal airway volume. Females showed a statistically significant positive correlation between the pharyngeal airway volume and sagittal position of maxilla and mandible; they also showed a negative correlation between oropharyngeal airway volume and the mandibular plane angle.
Overall, the pharyngeal airway space differs significantly between males and females. Craniofacial morphology does have a significant effect on the pharyngeal airway, especially on the oropharyngeal airway volume.
本研究旨在通过锥形束 CT（CBCT）确定咽腔容积与颅面形态之间的相关性。此外，该研究分析了性别对咽腔容积的影响。方法：纳入 80 例符合纳入标准的男性和女性患者（平均年龄：15.38 ± 1.10 岁）的 80 例 CBCT 扫描。使用 In Vivo Dental 5.1 软件评估咽腔容积的 CBCT 扫描。此外，还使用 CBCT 衍生的侧位头颅侧位片评估了各种颅面形态参数。为了检查性别对气道容积的影响，进行了 T 检验。使用 Pearson 相关分析测量气道容积与颅面参数之间的相关性，然后进行回归分析。 < 0.05 被认为具有统计学意义。结果：男性的平均气道容积明显大于女性。上颌平面倾斜度与咽腔容积呈显著负相关。相反，下颌长度和下磨牙倾斜度与口咽和总咽腔容积呈正相关。女性的咽腔容积与上颌和下颌矢状位置呈显著正相关；口咽气道容积与下颌平面角呈负相关。结论：总体而言，男性和女性的咽腔空间差异显著。颅面形态对咽气道有显著影响，尤其是对口咽气道容积的影响。
