Summary
Titanium pistons cause MRI artifacts that prevent interpretation of the vestibule. This disadvantage is not present on CT but the vestibule is not visible. Hence the interest in creating a model with 6 reference cuts in order to position the utricle and the saccule in the vestibule in CT. Furthermore, the scanner has fewer contraindications, greater availability and a shorter examination time than MRI.
Detailed description
The aim of the study is to analyze six normal sections chosen as reference in histology, high resolution T2 MRI and CT in order to compare them with precise topographical landmarks to position the posterior membranous labyrinth in CT. Then, apply the investigators' observations to cases of operated otosclerosis.
