Results:
The mean anterior-posterior (AP) diameter at the base on the basal turn, the AP diameter at the midpoint of the IAC, the anterior and posterior length of the internal acoustic canal were measured. 57.14% of the internal acoustic canals observed presented with a cylindrical, 40.48% was funnel-shaped and 2.38 % was bud-shaped. A statistically significant difference was found between the diameters of the male and female internal acoustic meatii.
