Age and sex determination in forensic sciences are primary components of any skeletal analysis. As most bones used for sex determination are recovered in incomplete state, it is often necessary to use bones that are recovered intact e.g., the maxillary sinus. Cone Beam Computed Tomography (CBCT) can provide precise information about complex anatomical structures, as it is characterized by rapid volumetric image acquisition with high resolution.
The present study was designed to evaluate the size and volume of Maxillary Sinus (MS) in determining gender by CBCT.
Bilateral maxillary sinus images (left and right) were acquired for 100 patients (50 females and 50 males) and different parameters (width, length, height, area, perimeter and volume) were measured and evaluated. Mean and standard deviation of both maxillary sinuses measurements were calculated and compared. The data was subjected to discriminative statistical analysis and analysed using unpaired t-test.
Comparison between male and female groups showed statistically insignificant differences on both the right and left sides with respect to the maxillary sinus length, height, area, volume and perimeter. However, the female group showed statistically significant higher values for left side MS width (p=0.041) and left side MS width can be used to determine gender with an overall accuracy of 60%. The final result of discriminative analysis shows that the ability of the maxillary sinus to identify gender was 68% in males and 74% in females with an overall accuracy of 71%.
Maxillary sinus width can be used as an aid in forensic anthropology for gender determination.
法医学中的年龄和性别判定是任何骨骼分析的主要组成部分。由于用于性别判定的大多数骨骼都是不完整状态下回收的，因此通常有必要使用完整回收的骨骼，例如上颌窦。锥形束计算机断层扫描（CBCT）能够提供有关复杂解剖结构的精确信息，其特点是能够快速获取高分辨率的容积图像。
本研究旨在评估CBCT在上颌窦（MS）大小和体积用于性别判定方面的情况。
为100名患者（50名女性和50名男性）采集双侧上颌窦图像（左右两侧），并测量和评估不同参数（宽度、长度、高度、面积、周长和体积）。计算并比较双侧上颌窦测量值的均值和标准差。对数据进行判别统计分析，并使用非配对t检验进行分析。
男性和女性组之间在上颌窦长度、高度、面积、体积和周长方面，左右两侧均显示出无统计学意义的差异。然而，女性组左侧上颌窦宽度显示出统计学上的显著更高值（p = 0.041），左侧上颌窦宽度可用于性别判定，总体准确率为60%。判别分析的最终结果表明，上颌窦识别性别的能力在男性中为68%，在女性中为74%，总体准确率为71%。
上颌窦宽度可作为法医人类学中性别判定的辅助手段。
