Abstract

Facial soft tissue thickness (FSTT) data are currently widely used in forensic and medical science. In the forensic sciences, they form the basis for craniofacial reconstruction and identification methods. Since there are few FSTT data in the Slovak population, this study aims to enrich the data in well-defined age categories, taking into account differences between sexes and body mass index (BMI). The sample consisted of 127 participants aged 17 to 86 years from Slovakia. In addition to biological sex and age information, stature and body weight were recorded to calculate BMI. Subsequently, 17 facial anthropometric landmarks were used to measure FSTT using a noninvasive General Electric LOGIQe R7 ultrasound device. The mean values of FSTT were greater in the mouth region in males and in the zygomatic and eye regions in females. Differences between males and females, regardless of sex and BMI, were significant only at two landmarks. When BMI and age were taken into account, there were differences in 12 of 17 landmarks. Linear regression results showed the strongest correlation of most landmarks with BMI, followed by age and sex. When the FSTT was estimated in association with sex/age/BMI, landmarks in the zygomatic, mandibular, and frontal regions were the best regressors. The results of the present study demonstrate that B-mode ultrasound measurements of FSTT can be used in facial reconstruction as a function of BMI, age, and sex of the subject. Furthermore, the present regression equations can help practitioners in the forensic/medical field to calculate individual tissue thickness.

超声波测量的生物参数与面部软组织厚度之间的关系及其法医学意义。
面部软组织厚度(FSTT)数据目前广泛应用于法医学和医学科学。在法医学中,这些数据是颅面重建和鉴定方法的基础。由于斯洛伐克人口中的 FSTT 数据很少,本研究旨在丰富明确界定年龄类别的数据,同时考虑到性别和体重指数(BMI)之间的差异。样本包括来自斯洛伐克的 127 名 17 至 86 岁的参与者。除生理性别和年龄信息外,还记录了身材和体重,以计算体重指数。随后,使用通用电气公司的无创 LOGIQe R7 超声波设备测量了 17 个面部人体测量地标。男性口腔区域的 FSTT 平均值较大,女性颧骨和眼部区域的 FSTT 平均值较大。无论性别和体重指数如何,男性和女性之间的差异仅在两个地标处显著。当考虑到体重指数和年龄时,17 个地标中有 12 个存在差异。线性回归结果显示,大多数地标与体重指数的相关性最强,其次是年龄和性别。当估计 FSTT 与性别/年龄/体重指数相关时,颧骨、下颌和额部的地标是最佳回归因子。本研究的结果表明,B 型超声波测量的 FSTT 值与受试者的体重指数、年龄和性别有关,可用于面部重建。此外,本回归方程可帮助法医/医学领域的从业人员计算个体组织厚度。
