Objectives: The purpose of this study was to characterize the morphology of the internal auditory canal (IAC) during development using high resolution computed tomography (CT) and to analyze its dimensions, which will be determined by measuring the nearby areas and structures using a system of digital image processing. Patients and Methods: CT images of the IAC of 110 normal subjects aged 1 to 92 years (mean age, 46.5 years) of both genders were reviewed to determine the shape, area, open ing width (OW), longitudinal length (LL), vertical diameter (VD) and distance from the ves tibular aqueduct. Results: The shapes observed in children and adults were funnel-shaped (74% and 58.3%, respectively), cylindrical (22% and 30.9%, respectively) and bud-shaped (4% and 10.8%, re spectively). The measurements by CT in children were: area= 50.30 mm 2 , OW = 7.53 mm, length = 11.17 mm, VD = 4.82 mm and the distance between the IAC and the vestibular aque duct (VA) = 12.63 mm. In adults, the measurements were: area = 44.64 mm 2 , OW = 7.10 mm, length = 9.84 mm, VD = 4.47 mm and the distance between IAC and VA = 11.17 mm. Conclusions: CT images showed that the IAC has different shapes and when the measure ments obtained for children were compared with those of adults, the parameters that pre sented statistically significant differences in either gender were length and diameter.
