title: Profile of cochlear implant users of the city of Manaus.
abstract: BACKGROUND
  The cochlear implant is a device that is intended to substitute for the function of cochlear hair cells, electrically stimulate auditory nerve fibers, and contribute to the perception of speech sounds. However, the surgical procedure alone is not enough for the user to achieve favorable results in habilitation/rehabilitation.
  
  
  OBJECTIVE
  To characterize the patients from Manaus who have received cochlear implants based on the criteria for surgery.
  
  
  METHODS
  We conducted a retrospective cross-sectional study of 15 cases and recorded etiological aspects of deafness, age, gender, duration of implant use, use of hearing aids, and participation in individual therapy. Data were recorded in a protocol designed specifically for this purpose. All patients were natives of Manaus.
  
  
  RESULTS
  The leading etiological aspect was ototoxicity associated with prematurity in newborns undergoing treatment in the neonatal intensive care unit. The age at surgery is carefully observed in the evaluation of implant centers, as well as if the candidate is pre-or post-lingual. In this study, 73% of patients were pre-lingual and did not benefit from hearing aids. As to the degree and type of hearing loss, 93% had audiological reports indicating profound bilateral sensorineural hearing loss and 7% had severe bilateral sensorineural hearing loss. This latter finding confirmed one of the basic principles of implant placement.
  
  
  CONCLUSIONS
  This study allowed us to verify that there are reduced number of cochlear implant recipients in Manaus, but they have met the criteria required by implant centers located in other states of Brazil.
