Abstract
Two hundred and six temporal bone CTs of children from 014 to 1895 years were retrospectively selected and reviewed Temporal bones were measured in a standardized slice orientation using the length of the basal turn of the cochlea the length and width of the petrous bone the coronal extent trailing edge and anterior–posterior dimension of the temporal bone and the angle between petrous bone’s length and the midsagittal line in the axial plane showing the basal turn of the cochlea in its greatest extent Two sutures two synchondroses and three fissures of the temporal bone were evaluated and gradedChosen measurements and calculations demonstrate an increase of values from 0 to 18 years with the greatest increase occurring during the first 2 years of life The angle between the basal turn of the cochlea and the midsagittal line shows a large variability Logarithmic trend lines illustrate larger measurements of males as compared to females The ratio of the basal turn of the cochlea and the length of the petrous bone is about 141 f/m during the first year of life and about 161 f/168 m from 17 years onwards Results of suture closure are described using boxandwhisker plots
