This study aims to develop standardized techniques and measurements from three-dimensional (3-D) reconstructed images of the frontal sinus in the identification of Koreans.
Radiographs and computed tomography (CT) images have been increasingly applied and accepted in forensic sciences. Along with radiographs and CT images, the frontal sinus is often used for the individual identification because of its unique and unchangeable characteristics. The purpose of this study is to define the usefulness of three-dimensional (3-D) images of the frontal sinus for identification. CT images from 119 Korean cadavers were built up for 3-D reconstruction and surveyed with 15 measurements. The total volume of the sinus, some nonmetric characteristics, and the bilateral asymmetry index in men differed significantly from those in women (p less than 0.05). The digit codes, 6 sections and 10-digit number, were almost able to accurately identify individuals (98 percent). This study showed a statistical difference between the sexes and classified the fused and prominent middle sinuses for the first time. This proposed method for identification is more accurate than those used in other studies. Abstract published by arrangement with John Wiley & Sons.
