Estimation of Normal Semi-circular Canal Dimensions on Computed Tomography.

Aims: To measure and compare length, width and luminal diameters of semi-circular canals (SCC) on Multiplanar reformatted CT images in individuals without any features of vestibular dysfunction.

Materials And Methods: A prospective, cross sectional, observational study was conducted in a tertiary care hospital in October - November 2021. Multiplanar reformatted CT temporal bone images of 50 participants without features of vestibular dysfunction were used to measure the curved lengths, widths and luminal diameters of the three semi-circular canals.
