[Cochlear implants in obliterated or ossified cochleas]

Abstract

Our last cases of cochlear implants in obliterated or ossified cochleas are presented, and we had described the surgical technique for double-array or compressed system. In our opinion the best surgical method is the combined approach (endoaural with aticotomy view and posterior timpanotomy) for increased promontory view. This technique provides the advantage that it always preserve the posterior wall of the external ear canal, and the array is positioned easily.
