title: [Extended indications for cochlear implantation. The Freiburg results in patients with residual hearing].
abstract: The usual indication for a cochlear implant (CI) is acquired deafness in patients for whom conventional hearing aids are of no benefit. The question is whether CI is superior to the best conventional hearing aids for patients with some residual hearing, but who achieve only minimal speech recognition (< 30% in the Freiburg monosyllable word test at 70 dB (I) SPL) with optimal hearing aids. We report our experience with five patients with residual hearing who underwent cochlear implantation (Nucleus Mini 22 and 24) on the worse side. The patients were examined preoperatively and at 1, 6 and 12 months following activation of the implant. The Freiburg monosyllabic word test, the Göttingen sentence test and consonant recognition were used to assess postoperative results. All patients benefitted from CI when test scores were compared with preoperative ones. All patients achieved a score in the Freiburg monosyllabic word test of more than 60% at 70 dB (I) SPL 12 months post switch-on. Four patients achieved a score of more than 85% in the Göttingen sentence test. These results and the progress made in cochlear implant technology are an impetus to continue discussions of various considerations of criteria for cochlear implants and possibly extend these for patients with severe hearing impairment.
