| Outline of Final Research Achievements |
The purpose of this study is to evaluate the efficacy of positron emission tomography (PET) as a tool of preoperative examination which predicts the usefulness of second implant in bilateral cochlear implant (CI) user. Seventeen patients with bilateral profound sensorineural hearing loss were examined. Glucose metabolism of the brain was measured with PET/CT after and before electrical auditory stimulation. Correlation between the postoperative results and primary auditory cortex activation of patients who underwent unilateral CI was not observed. In the pediatric patients who underwent bilateral CI, Good postoperative hearing results of the second implant were exhibited in a case that had the primary auditory cortex activation. On the other hand, in case the primary auditory cortex activation was not recognized exhibited poor postoperative results. Preoperative evaluation using PET/CT is potentially useful as test to predict the effect of the second implant.
