275 THI Effect of cochlear implantation in patients with singlesided deafness. Masahiro Takahashi, Satoshi Iwasaki, Shinya Nishio, Ryosuke Kitoh, Seiichi Shinden,Sho Kanzaki, Kaoru Ogawa and ShinIchi Usami Department of Otolaryngology, International University of Health and Welfare, Mita hospital Department of Otorhinolaryngology, Shinshu University School of Medicine Department of Otolaryngology, Saiseikai Utsunomiya Hospital Department of Otorhinolaryngology Head and Neck Surgery, Keio University School of Medicine Patients with single sided deafness SSD often experience difficulties in hearing and have a reduced quality of life. In Europe, cochlear implantation is already performed for patients with SSD. We performed cochlear implantation in five patients with SSD from four facilities. We diagnosed one case of SSD at our department. Speech perception in noise, sound localization and tinnitus suppression with improved binaural hearing were observed four years after the cochlear implantation. We hope that cochlear implantation would come to be accepted in the future for enabling binaural hearing in patients with SSD.
