Abstract
- Obstruction of the fluid spaces of the cochlea was previously thought to contraindicate cochlear implantation due to difficulties of electrodes insertion and questions about potential benefits. However, the concept of implantation of ossified cochlea and its subsequent acceptance have progressed rapidly. A 62-year-old man complained of both hearing loss after meningitis and temporal bone CT scan showed partial obliteration of cochlea bilaterally. We fully inserted 22 active electrodes via scala vestibuli without difficulty. The purpose of this study is to determine the safety and efficacy of scala vestibuli electrode insertion in partially ossified cochlea.
