Imaging guided Decision making in Cochlear Implantation.

Abstract :

 Background: Imaging procedures are a mainstream tool in the daily ENT workflow.  Cochlear Implant patients are representing a special population with specific demands for imaging. There are different imaging techniques available for pre–operative evaluation. Objective: High–resolution computed tomography (HRCT) is the standard imaging technique used in cochlear implantation. However, cochlear and retrocochlear soft–tissue abnormalities may not be detected with HRCT alone. To determine whether magnetic resonance imaging (MRI) and HRCT provides clinically significant information in the evaluation of candidates for cochlear implants, we performed this study. Study type: Prospective nonrandomized observational study Setting: Otorhinolaryngology department at civil hospital ahmedabad. Materials and method: 207 patients  with profound heå loss underwent HRCT and MRI scans using 1.5 tesla scanner with 16 channel head coil. MRI was performed and axial, coronal and sagittal reformatted images and were analyzed systematically. Result: Various anamolies were found during HRCT and MRI and these findings were significant for clinical decisions regarding candidacy for surgery, side selection for surgery, and surgical technique in cochlear implantation. Conclusion: Study concludes that HRCT and MR provides accurate anatomical delineation of complex soft tissue of inner ear and 3D reconstruction improves preimplant evaluation.
