초록
Congenital aural atresia (CAA) is usually accompanied by an anomalous course of facialnerves, which may run over the round window niche toward the promontory in some cases ofCAA. Very rarely, cochlear malformation might coexist at the same ear which has CAA, inwhich case cochlear implantation can be difficult due to anomalous facial nerve. Herein wepresent a case of cochlear implantation performed in a child who had CAA along with cochlearhypoplasia and cochlear nerve aplasia. The mastoid segment of facial nerve was displacedanteriorly, running over the round window niche. The surgery was done successfully usingthe round window approach without facial nerve injury.
Abstract
Congenital aural atresia (CAA) is usually accompanied by an anomalous course of facialnerves, which may run over the round window niche toward the promontory in some cases ofCAA.

Herein wepresent a case of cochlear implantation performed in a child who had CAA along with cochlearhypoplasia and cochlear nerve aplasia. The mastoid segment of facial nerve was displacedanteriorly, running over the round window niche. The surgery was done successfully usingthe round window approach without facial nerve injury.
