Paget's disease and cochlear implantation.
Paget's disease of bone is a common disorder of unresolved etiology characterized by excessive bone resorption followed by excessive bone formation. If the skull is affected this may result in hearing loss and eventually develop into profound deafness. To date, no cases of cochlear implantation in patients with Paget's disease have been reported. The authors present a case of radiographically confirmed Paget's disease of the skull in a 77-year-old man with a 20-year history of progressive bilateral sensorineural hearing loss who underwent cochlear implantation. A successful insertion of the Nucleus 24 Contour electrode array was achieved without surgical and postoperative complications. At the 10 months' postoperative evaluation, the patient had gained useful open-set speech perception. In quiet conditions, his performance scores on the word and sentence recognition tests were 100 and 98 per cent, respectively. In the presence of noise (at +10 dB. signal-to-noise ratio), his performance scores on the word and sentence recognition tests were 96 and 94 per cent, respectively.
