CT Scalar Localization

Mayo Clinic

Overview

Comparing the location of cochlear implants to level of retained hearing.

Subjects who have undergone cochlear implant surgery will have a CT scan to determine the exact anatomical location of the implant. This location will then be compared with audio testing levels and operative reports to determine any advances in implantation technique that would result in more preserved hearing
