Cochlear implantation in an NPC patient post-irradiation presenting with electrode array extrusion through the posterior canal wall

Cochlear implant is a viable rehabilitation option for sensorineural hearing loss in post-irradiated patients [1,2]. The retro-cochlear auditory pathways appear to remain functionally intact in the long term in patients who have had irradiation for nasopharyngeal carcinoma, [3] and the overall hearing outcomes post-cochlear implant were similar in post-irradiated patients and patients who had no prior irradiation [4].
