Morphometric Analysis of the Internal Auditory Canal by Computed Tomography Imaging

Background: Many clinical and experimental studies have been done to analyze the anatomical and functional aspects of the internal auditory canal (IAC) in human beings since there are great inter-individual variability and structural variations that may occur regarding the other adjacent structures....
