Title: Application value of Magnetic Resonance Hydrography of Inner Ear Imaging in Cochlear Implantation
Abstract: Objective To explore the application value of magnetic resonance hydrography of inner ear imaging in cochlear implantation. Methods 146 patients underwent cochlear implantation in our hospital were selected from January 2012 to January 2014 as the research objects. Internal auditory canal MRI and CT were performed before the surgery. All the imaging data was analyzed and statistically summarized. The application value of magnetic resonance hydrography of inner ear imaging in cochlear implantation were explored. Results Of all the 146 cases(292 ears), 13 cases(20 ears) were detected with vestibular aqueduct abnormality by MRI and 5 cases by CT; 15 cases(19 ears) were detected with inner ear malformations by MRI and 11 cases by CT with 4 cases of missed diagnosis. 5cases(8 ears) were detected with internal auditory canal stenosis by MRI and 2 cases by CT with 3 cases of missed diagnosis. 4 cases(5 ears) were detected with cochlear fibrosis by MRI and 4 cases by CT. The diagnostic accuracy was 77.40%(113/146) simply based on CT scan, and the diagnostic accuracy was 93.84%(137/146) simply based on MRI. Conclusions Magnetic resonance hydrography techniques can be applied to the imaging evaluation of inner ear before cochlear implantation. It can provide accurate and reliable anatomical information of the membranous labyrinth and auditory canal nerve and accurate basis for the diagnosis of cochlear fibrosis and neural development, and it has guiding significance for the choosing of treatment scheme.
