Abstract

Purpose

develop and validate a formula, through a discriminant analysis of sex estimation, evaluating maxillary sinus in cone beam computed tomography scans in a Brazilian population, comparing this formula with two other existing ones.

Methods

190 cone beam CT scans of Brazilian adults were retrospectively evaluated by an independent examiner. Measurements were performed in the right and left MS region: height, width, length, distance between the breasts, distance between infraorbital foramina, and volume in the ITK software. The sample was divided into female and male. T test, ANOVA, Tukey test and the ROC Curve was performed (p > 0,05).

Results

statistically significant differences were found in relation to the maximum height of the MS both right (p = 0,001) and left (p = 0,026) between sexes and the maximum length in the right MS (p = 0,01). Regarding the comparison of MS volume according to the different analysis methods, statistically significant differences were found between sexes for the right MS when using the method by Bangi et al. (p = 0,012) and the volume of the left MS in females (p < 0,001). Comparing the three classification models, statistically significant differences were found between the proposed method and the classification by Bangi et al. (p < 0.007). The ROC curve showed greater accuracy in the classification proposed in this work.

Conclusion

the new proposed formula obtained better predictions of sexual dimorphism, when compared to classifications already described in the literature.

不同上颌窦体积分析方法的比较以及锥形束计算机断层扫描新方案的验证。

目的：通过性别估计的判别分析，开发并验证一个公式，在巴西人群的锥束计算机断层扫描中评估上颌窦，并将该公式与其他两个现有公式进行比较。方法：由独立检查者对190例巴西成年人的锥束CT扫描进行回顾性评估。在ITK软件中对左右MS区域进行测量：高度、宽度、长度、乳房之间的距离、眶下孔之间的距离和体积。样本分为女性和男性。进行了T检验、方差分析、Tukey检验和ROC曲线（p>0.05）。结果：性别间MS的最大身高（p=0.001）和最大长度（p=0.001。关于根据不同分析方法的MS体积的比较，当使用Bangi等人的方法时，发现右侧MS的性别之间存在统计学上的显著差异。（p=0.012）和女性左侧MS的体积（p结论：与文献中已经描述的分类相比，新提出的公式获得了更好的两性异形预测。
