Cochlear implantation is a reliable and safe tool to rehabilitate patients with severe-to-profound sensorineural hearing loss, who get limited benefits from traditional hearing aids. Electrode misplacement is a rare but significant problem that fails to provide benefits and may cause injury to the nearby structures. We present a case that underwent mastoidectomy first to remove cholesteatoma, followed by cochlear implantation with electrode misplacement into the petrous area, with sustained hearing benefits and without any injury to the surrounding structures.
