To compare maxillary sinus volumes and surface areas among individuals with Class III skeletal patterns, with different sagittal positions of maxilla and Class I patients with normal jaw positions using cone-beam computed tomography (CBCT).
CBCT images of 168 patients were analyzed retrospectively. The calculated surface areas and sinus volumes of 58 patients with Class I, normal mandibular and maxillary position (0<ANB<4, 84>SNA>80, 82>SNB>78) were compared with 61 patients with Class III retrognathic maxillary and normal mandibular positions (MRs) (ANB<0, SNA<80, 82>SNB>78) and 49 patients with Class III normal maxillary and prognathic mandibular positions (MP) (ANB<0, 84>SNA>80, SNB>82). Also, volume differences between genders and sides were investigated. One-way ANOVA and t-test were used to compare age, gender, skeletal patterns, and maxillary sinus measurements.
CBCT images of 94 females and 74 males were examined. There was no statistically significant difference in the right and left maxillary sinus volume and surface area measurements among Class I, Class III MR, and Class III MP groups (p>0.05). When the maxillary sinus volume and surface area were evaluated according to gender, the right maxillary sinus surface area and volume of males were found to be statistically significantly higher than those of females (p=0.012 and p=0.024). Similarly, the left maxillary sinus surface areas and volumes of males were also found to be significantly higher than those of females (p=0.000 and p=0.002).
Different sagittal positions of the maxilla do not appear to affect maxillary sinus volume, and males tend to have greater maxillary sinus volume than females. CBCT images can be used to calculate intrabony air spaces.
使用锥形束计算机断层扫描（CBCT）比较III类骨骼型个体、上颌骨矢状位不同的个体以及颌骨位置正常的I类患者的上颌窦体积和表面积。
回顾性分析168例患者的CBCT图像。将58例I类、下颌和上颌位置正常（0<ANB<4，84>SNA>80，82>SNB>78）患者的计算表面积和窦体积与61例III类上颌后缩和下颌位置正常（MRs）（ANB<0，SNA<80，82>SNB>78）患者以及49例III类上颌正常和下颌前突（MP）（ANB<0，84>SNA>80，SNB>82）患者进行比较。此外，研究了性别和左右侧之间的体积差异。使用单因素方差分析和t检验比较年龄、性别、骨骼型和上颌窦测量值。
检查了94例女性和74例男性的CBCT图像。I类、III类MR和III类MP组之间左右上颌窦体积和表面积测量值无统计学显著差异（p>0.05）。根据性别评估上颌窦体积和表面积时，发现男性的右上颌窦表面积和体积在统计学上显著高于女性（p=0.012和p=0.024）。同样，男性的左上颌窦表面积和体积也显著高于女性（p=0.000和p=0.002）。
上颌骨不同的矢状位似乎不影响上颌窦体积，男性的上颌窦体积往往比女性大。CBCT图像可用于计算骨内气腔。
