Application of “banana cochleostomy” and looped electrode insertion for cochlear implantation in children with common cavity malformation and cystic forms of cochlear hypoplasia

We hope that utilization of the “banana cochleostomy” and insertion of the looped cochlear implant electrode in the implantable cystic spaces of children with malformed inner ears will facilitate and simplify the surgical technique in this difficult procedure and additionally, in revision surgical cases. To our knowledge, the looped insertion and banana-shaped cochleostomy have not been reported previously.
