Abstract

Aim: The purpose of this study was to evaluate the significance for sex determination of the measurement of the area formed by projection of 3 craniometric points related to the mastoid process (the porion, asterion, and mastoidale points) of 3D reconstructed computed tomography (CT) of skull and the result is compare the result of manual measurement of the area formed by projection of 3 craniometric points related to the mastoid process. Method: 3D reconstructed CT of 40 males and 40 females were analysed. The three craniometric points were located and marked on both side of the 3D skull and the measurement was done by advanced post processing techniques. In manual measurement 40 males and 40 female skull were analyzed by digital caliper (0.01mm). The area of mastoid triangle was calculated by means of the Heron’s formula. The result of CT reading and Manual reading is analyzed for the sex determination and the both result is compared. Result: From this study the areas of the male CT measurement of Mastoid is 828.53±118.54 mm2which is greater than female Mastoid which is 578.24±71.53 mm2 (T test value 9.901and P Value 001). Area of the male Mastoid which is measured by manual 805.87±90.99 mm2 which is greater than female Mastoid which is 620.56±90.63 mm2 (T test value 10.202and P Value 001). Conculsion:The area of the mastoid triangle measured by manual and 3D reconstructed CT skull are used to determine the sex of the skull and there is no significant deference between CT scan and Manual method of area measurement of mastoid process in sex determination of south Indian population .
