We made an anatomic study using a convenience sample of 20 patients, most of them referred to our institution for depicting internal auditory malformations that justify sensorineural deafness or for surgical planning of cochlear implants. All patients underwent a multislice temporal bone CT and oblique single slice reformation postprocessing in six proposed different planes corresponding to cochlear basal turn, apical basal turn, malleoincudal complex, stapes, and facial channel. Anatomic and pathologic characterization of some middle and inner ear structures, difficult to evaluate in standard axial and coronal planes, can be improved using this technique.
