The pars petrosa ossis temporalis has been studied for the purpose of sex estimation in many cadaveric studies. Since several studies have demonstrated that discriminant function equations used to determine the sex of a skeleton are population specific, the purpose of this study was to evaluate the capability of computerized tomography of temporal bone of living individuals to estimate the sex from measuring the lateral angle of internal acoustic canal meatus and drive similar equation for the size of the angle. Multidetector computerized tomography (MDCT) of the temporal bone was done to 120 patients (59 females and 61 males) to measure the lateral angle size. The mean angle is greater in females (50.34±6.178) than males (42.39±5.77). Measurements of 37.187° and lesser were 83.6% specific for males and measurements higher than 37.187° were 77.96% specific for females. Finally, it is concluded that the petrous portion of temporal bone is useful for sex estimation in Egyptian population
