Cochlear implantation in canal wall down mastoid (CWD) cavities is fraught with the issue of how best to manage the mastoid cavity. Decision points include whether the external auditory meatus should be overclosed, whether the implantation should be staged, or even if the eustachian tube should be plugged. Given these options, we sought to describe our experience of cochlear implantation in CWD cavities. Among evaluation of subjects ≥18 years of age, 9 had cochlear implants placed in CWD mastoid cavities, 7 of which had the external auditory meatus overclosed, while 2 maintained open cavities following implantation. With an average follow-up of 36.7 months (median, 22.8 months), 2 subjects who had overclosure developed meatal dehiscences requiring further intervention, while no complications were observed in the 2 patients who maintained open cavities.
