THE CONGRUENCE BETWEEN CRANIOMETRIC OF ADULTS HEAD CT SCAN WITH AGE AND GENDER A STUDY IN RADIODIAGNOSTIC DEPARTMENT OF dr. SOETOMO GENERAL HOSPITAL SURABAYA AT AUGUST-DECEMBER 2019

Abstract

BACKGROUND: Enforcement of the identification of dead victims is very important for personal, social and legal interests. However, identification of large numbers of victims (mutilation, decomposition, burning, destroyed) is not easy. This study conducted a craniometric study of adult head CT scans in Indonesia, particularly at the dr. Soetomo General Hospital Surabaya, related to the identification of a person, so that it can be used in Disaster Victim Investigation (DVI). OBJECTIVE: Analyzing craniometric data from adult head CT scans at the Radiodiagnostic Installation of dr. Soetomo General Hospital Surabaya to identify age and gender. METHODS: Retrospective analytic observational. RESULT: A total of 204 adult head CT scans at the Radiodiagnostic Installation of dr. Soetomo General Hospital in August-December 2019 were evaluated retrospectively, consisting of 112 men (54.9%) and 92 women (45.1%). Of the 22 craniometrics evaluated, the test results showed no correlation between age with 15 male craniometrics and 17 female craniometrics (ρ>0.05), weak correlations in 6 male craniometrics and 5 female craniometrics (ρ<0.05; r= 0.21 to 0.40), and a very weak correlation in 1 male craniometrics (ρ<0.05; r= 0.00 to 0.20). There are 10 craniometrics that have differences with statistically strong evidence between male and female groups (ρ<0.001). Discriminant analysis showed a cutting score of-0,00025, with an accuracy rate of gender identification of 91.2%. CONCLUSION: Craniometrics from adult head CT scans can be used for gender identification with an accuracy rate of 91.2%, but cannot be used for age identification.
