A computed tomography assessment of frontal sinus for sex determination in the Thai Population
Keywords:
frontal sinus, computerized tomography, sex, forensic medicineAbstract
The frontal sinus has been used for identification since 1921. It was completed with other parts of bones are destroyed or lost. The aim was to study the parameters of the frontal sinus from computed tomography (CT) to evaluate sex determination. This retrospective study was done at HRH Maha Chakri Sirindhorn Medical Center in Thailand. The 270 subjects for CTs were randomly selected and included 135 men and 135 women. These variables were studied: the absence of frontal sinus, scalloping, complete septum length, incomplete septum length, maximum height, maximum width, maximum total width, and maximum AP diameter. The results showed a mean age of 58.83 ± 15.81 years (men: 59.98 ± 15.01 years and women: 57.68 ± 16.56 years) and five variables that statistically differed (left maximum height, left maximum width, right AP diameter, left AP diameter, and total maximum width). The ROC curve was analyzed at a cutoff point for each variable. The accuracy percentage was in the range of 56.47 - 74.90. The use of frontal sinus CT scans is another way of conducting sex determination in the Thai population. The frontal sinus configuration study will be helpful for further identification.
