The aim of this study was to determine whether paranasal sinus dimensions and volume can be useful to identify gender and age estimation for ancient skulls using cone-beam computed tomography (CBCT) images.
CBCT scans of 32 ancient skulls of approximately 1000 years of age were included in this retrospective study. The gender and age estimation of the skulls were made by an independent anthropologist, which was considered as the gold standard. Paranasal sinuses' dimensions (width and height) and volumes of each sinus were measured from the CBCT data set that was linked to the three-dimensional rendering software (Anatomage, Invivo 5.2). All measurements were performed by an independent observer. Intra-observer analysis was made. Mann-Whitney and Kruskal-Wallis tests were used to compare paranasal sinus parameters in terms of age estimation and gender (p < 0.05).
The results demonstrated no statistically significant difference between measurements (p < 0.05). The measurements were found to be highly reprodu- cible. The mean volumes of frontal and sphenoid sinus were found to be higher in males. The distance from anterior-posterior wall of sphenoid sinus in axial sec- tions is larger in males (p > 0.05). The frontal sinus width and volume increased statistically with age above 60 years of age (p > 0.05).
The paranasal volume and dimensions' measurements from CBCT data can be a promising technique to determine gender and age of ancient skulls because of its lower voxel sizes and higher resolution.
本研究的目的是确定使用锥形束计算机断层扫描（CBCT）图像时，鼻窦尺寸和容积是否有助于识别古代颅骨的性别和估计年龄。
本回顾性研究纳入了32具约1000岁古代颅骨的CBCT扫描图像。颅骨的性别和年龄估计由一名独立的人类学家进行，其结果被视为金标准。从与三维渲染软件（Anatomage，Invivo 5.2）相连的CBCT数据集中测量鼻窦的尺寸（宽度和高度）以及每个鼻窦的容积。所有测量均由一名独立观察者进行。进行了观察者内分析。使用Mann-Whitney和Kruskal-Wallis检验比较鼻窦参数在年龄估计和性别方面的差异（p<0.05）。
结果显示测量值之间无统计学显著差异（p<0.05）。发现测量具有高度可重复性。发现男性的额窦和蝶窦平均容积较高。男性蝶窦轴向截面的前后壁距离更大（p>0.05）。60岁以上人群的额窦宽度和容积随年龄增长有统计学意义的增加（p>0.05）。
由于CBCT数据的体素尺寸较小且分辨率较高，从CBCT数据测量鼻窦容积和尺寸可能是确定古代颅骨性别和年龄的一种有前景的技术。
