Paget’s disease is a common bone remodeling disorder that typically begins with excessive bone resorption in the elderly. Bilateral progressive hearing loss is the most frequently encountered complication of Paget’s disease. The types of hearing loss identified by audiometry are conductive, sensorineural, or both. However, the precise mechanism of hearing loss remains unclear, and the treatment has been controversial. We present a 73-year-old man who suffered from bilateral progressive hearing loss due to Paget’s disease. Potent bisphosphonates, oral risedronate in daily adjusted dosages for 6 months, did not decrease or suppress the worsening of the hearing loss. The Nucleus CI24 Contour electrode array was successfully inserted on the left side without surgical and postoperative complications. The Japanese open set monosyllable word recognition test in a sound field at 65 dB had a result of 74%. This cochlear implantation can be an indication for cases of profound hearing loss due to Paget’s disease.
