Four and a half years have passed since cochlear implantation became an authorized treatment with health insurance coverage in Japan. Reviewing clinical courses of 48 implant (Nucleus CI-22M, SPEAK strategy) users from our hospital, the effectiveness of the procedure was discussed. No serious surgical and postoperative complications were experienced in our series.
Preoperative evaluation of the candidates, in terms of their cochlear functions and anatomy, is important to make indication. Three-D reconstructed MRI images are very useful to grasp thepathological state of the whole cochlea. Cochlear implant can be a major medical breakthrough for people with profound to severe hearing impairment, even if they are wearing hearing aids. Considering the fact that many hearing aid users are getting better hearing ability with the implants, its indication may be further expanded to less severely impaired listeners.
