Vestibular Implant Imaging

Vestibular Implant Imaging CLINICAL REPORT HEAD & NECK A. Hedjoudje, D.P. Schoo, B.K. Ward, J.P. Carey, C.C. Della Santina, and M. Pearl ABSTRACT SUMMARY: Analogous to hearing restoration via cochlear implants, vestibular function could be restored via vestibular implants that electrically stimulate vestibular nerve branches to encode head motion. This study presents the technical feasibility and first imaging results of CT for vestibular implants in 8 participants of the first-in-human Multichannel Vestibular Implant Early Feasibility Study. Imaging characteristics of 8 participants (3 men, 5 women; median age, 59.5 years; range, 51–66 years) implanted with a Multichannel Vestibular Implant System who underwent a postimplantation multislice CT (n ¼ 2) or flat panel CT (n ¼ 6) are reported. The device comprises 9 platinum electrodes inserted into the ampullae of the 3 semicircular canals and 1 reference elec- trode inserted in the common crus. Electrode insertion site, positions, length and angle of insertion, and number of artifacts were assessed. Individual electrode contacts were barely discernible in the 2 participants imaged using multislice CT. Electrode and osse- ous structures were detectable but blurred so that only 12 of the 18 stimulating electrode contacts could be individually identified. Flat panel CT could identify all 10 electrode http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png American Journal of Neuroradiology American Journal of Neuroradiology
