초록

Otosclerosis is a localized disorder of bone metabolism involving the endochondral bone of the
otic and labyrinthine capsule. Both “advanced” and “very advanced” otosclerosis refer to the
state of otosclerotic involvement of the otic capsule, which has progressed to result in profound
deafness with undetectable bone and air conduction thresholds. Shea et al. estimated that 1.6%
of patients with otosclerosis had developed profound hearing losses, and that hearing improvements
after stapes surgeries in these patients were lower than the case of “not-advanced” otosclerosis.
Stapedectomy and hearing aid amplification could be tried, but cochlear implantation
is an established intervention for patients with profound sensorineural hearing loss due to otosclerosis.
Although the reported results of cochlear implantations in otosclerosis patients are not
significantly different from those of other cochlear implantees not affected by otosclerosis, in
former conditions, potential ossification of cochlea, facial nerve stimulation, and instability of
the results might take place. We report a case of otosclerosis histologically diagnosed for the
first time here in Korea, and for which cochlear implantation was successfully performed.
