Aim: To estimate the
age at death of Koreans whose age is unknown, based on the radiographic
analysis of thyroid cartilage.
Methodology: Thyroid cartilage
was separated from the larynx and dissected from the surrounding connective
tissue. Dedicated mammography was carried out in 124 thyroid cartilage
specimens, including 76 males and 48 females. Radiographed films were scanned
and 17 quantitative measurements were carried out with Adobe? Photoshop?
CS (version 8.0). These measurements were analyzed using the SPSS (version
22.0) statistical software package.
Results: The data were
divided into three age groups: G1- age between 15 and 30 years; G2- age
between 31 and 45 years; G3- age over 46 years. The discriminant functions
for the age group and multiple regression functions for each age group were
obtained for the age-estimation of male subjects, but the application for
female subjects was still limited due to small sample size for each age group.
Interpretation: The study
indicates that thyroid cartilage is useful in estimating the age for Korean
male subjects, whose age is unknown. Further investigations must be conducted
to verify the utility of this method and its application to female subjects.
Key words: Age estimation, Korean males, Mammography, Radiographic
