Cochlear Implantation Using the Endomeatal Approach in a Child with a Extremely Hypoplastic Mastoid / 대한이비인후과학회지

The classic surgical technique for cochlear implantation was first introduced by House in 1961. This technique includes a mastoidectomy and a posterior tympanotomy, which has been most widely used for cochlear implantation. However, this approach may result in the injury of the chorda tympani nerve or the facial nerve. To avoid the risk of the neural injury, several alternative surgical methods have been developed. The endomeatal approach is one of the several alternative techniques. We present, along with a review of literatures, a case of cochlear implantation using the endomeatal approach performed in a child with an extremely hypoplastic mastoid.
