Cochlear Implantation in a Patient with Advanced Otosclerosis

Abstract

The incidence of otosclerosis, especially the retrofenestral advanced type, is relatively low in Koreans compared to that of the Western population. A case is reported in which cochlear implantation was performed in a patient with advanced otosclerosis presenting with mixed profound hearing loss on one side and pure sensorineural hearing loss on the other side. Intraoperative or postoperative complications of cochlear implantation commonly encountered in patients with otosclerosis did not occur in our patient and successful auditory outcome could be achieved. The results are reported with the review of literature, and clinical considerations regarding cochlear implantation in otosclerosis are discussed.

Cochlear Implantation in Far Advanced Otosclerosis: A Case Report

“…The patient with far advanced otosclerosis derives significant benefit from cochlear implantation [8]. This report presents a case of successful CI without any intraoperative or postoperative complications performed in a patient with far-advanced otosclerosis.…”

“…The device was switched-on at postoperative one month 937 pulse, 900 rate), and NRT demonstrated good responses in the basal, middle, and apical electrodes. Facial twitching was observed during electrical stimulation on eletretodes [6,8,9]. The sound field test using the cochlear implant device demonstrated pure tone threshold of 20 dB HL 2 months after switch-on.…”

“…Copyright  Al-Lahham MF approaches including hearing aids, stapes surgery, or CI. Stapes surgery and hearing aid amplification might be initially considered in patients who still have residual hearing and measurable bone conduction since stapedotomy is a safe, simple, and low-cost procedure [8].…”
