The aim of this study was to evaluate the linear and volumetric measurements of the frontal sinus (FS), using cone beam computed tomography (CBCT) scans, for a discriminatory analysis of gender, age and facial skeletal pattern in a Brazilian population. A total of 300 CBCT scans were analyzed, measuring the height, width, length and volume of the FS. The measurements were divided into groups: sex, age (<20 to >40 years and >40 years) and facial skeletal pattern classes I, II and III. The function values in the centroid group were 0.675 for male and -0.292 for female. A rule was established indicating that if the value of D is greater than 0.19, the sample will be classified as male. The results showed a significant difference in women, who had significantly lower volume, width and depth than men (p-value<0.001, 0.003 and <0.001 respectively). No significant differences could be observed between the age and facial skeletal pattern groups. The results suggest that the FS measures of volume, height, width and depth have moderate discriminatory power for predicting gender in a Brazilian population. In conclusion, the results show that the FS has potential for determining gender, but the accuracy of the method and its applicability for analyzing age and facial skeletal pattern were limited in our population.
本研究的目的是利用锥形束计算机断层扫描（CBCT）评估额窦（FS）的线性和容积测量值，以便对巴西人群的性别、年龄和面部骨骼模式进行判别分析。共分析了300例CBCT扫描，测量了FS的高度、宽度、长度和容积。测量值被分为几组：性别、年龄（<20岁至>40岁以及>40岁）和面部骨骼模式I类、II类和III类。质心组中男性的功能值为0.675，女性为-0.292。制定了一条规则，表明如果D值大于0.19，样本将被归类为男性。结果显示女性存在显著差异，其容积、宽度和深度显著低于男性（p值分别为<0.001、0.003和<0.001）。在年龄组和面部骨骼模式组之间未观察到显著差异。结果表明，FS的容积、高度、宽度和深度测量值在预测巴西人群性别方面具有中等判别力。总之，结果表明FS具有确定性别的潜力，但在我们的人群中，该方法的准确性及其在分析年龄和面部骨骼模式方面的适用性有限。
