A Case of Intralabyrinthine Schwannoma Removal and Sequential BonebridgeTM Implantation / 대한이비인후과학회지

ABSTRACT

Intralabyrinthine schwannoma (ILS) is a rare benign tumor that arises within the membranous labyrinthine. Since hearing loss is inevitable after tumor removal in most cases, an appropriate rehabilitation method should be considered. A 41-year-old male, who was diagnosed with ILS underwent tumor removal via translabyrinthine approach, has subsequently experienced right-side deafness as a result. Seventeen months after the tumor removal, a surgery for hearing rehabilitation was performed. Since cochlear implantation was not doable due to cochlear ossification, an active transcutaneous bone conduction implant (BonebridgeTM , MEDEL) was placed at the sinodural angle. To the best of our knowledge, this is the first report describing hearing rehabilitation with BonebridgeTM implantation after ILS removal.
