Few studies have compared the relationship of MSV in the different craniofacial patterns. Hence, the purpose of this research was to evaluate maxillary sinus volume in different craniofacial patterns using cone-beam computed tomography.
This cross-sectional study included 100 pre-orthodontic patients mean aged 26.40 ± 6.77 (age ranged 21-64) years divided into different anteroposterior and vertical skeletal groups. From the cone beam computed tomography images using MIMICS 14.1 software, three-dimensional image of the maxillary sinus was constructed, and its volume was calculated.
The mean maxillary sinus volume was 20,279.50 ± 7800.33 mm. Among the anteroposterior skeletal groups, the mean maxillary sinus volume in skeletal Class II group is significantly larger than class III group (P < 0.05). Among the vertical skeletal groups, High-angle groups tend to have the largest maxillary sinus volume, though there were no significant differences among the groups (P > 0.05). Similarly, males have significantly larger maxillary sinus volume than females (P < 0.05). There was a positive correlation between ANB and maxillary sinus volume (P < 0.01).
Maxillary sinus volume is significantly larger in skeletal class II than in skeletal class III group and in males than in females (P < 0.05). These inferences have several implications in orthodontics, endodontics and oral surgery.
很少有研究比较不同颅面类型中 MSV 的关系。因此，本研究旨在使用锥形束 CT 评估不同颅面类型中的上颌窦容积。
本横断面研究纳入了 100 名正畸前患者，平均年龄为 26.40 ± 6.77 岁（年龄范围为 21-64 岁），分为不同的前后向和垂直骨骼组。使用 Mimics 14.1 软件从锥形束 CT 图像构建上颌窦的三维图像，并计算其体积。
上颌窦平均体积为 20279.50 ± 7800.33mm。在前后向骨骼组中，骨骼 II 类组的上颌窦平均体积明显大于 III 类组（P<0.05）。在垂直骨骼组中，高角组上颌窦容积最大，但各组间无显著差异（P>0.05）。同样，男性上颌窦容积明显大于女性（P<0.05）。ANB 与上颌窦容积呈正相关（P<0.01）。
上颌窦容积在骨骼 II 类中明显大于骨骼 III 类，在男性中明显大于女性（P<0.05）。这些推断在正畸学、牙髓学和口腔外科学中有一定的意义。
