A cochlear implant is an electronic device prescribed for people with severe and profound hearing loss; it is placed through surgery. In children it is indicated starting from one year of age and in adults there is no age limit.
Not all people benefit equally from an implant; many factors must be considered, including: time of being deaf, auditory memory, associated conditions, user and/or family engagement for all the processes including therapy, mappings, etc.
There are precise medical, audiological, psychological and psycholinguistic, indications, thus, a number of evaluations need to be performed to determine candidacy and how much benefit the cochlear implant may offer to a given person.
This surgery is being performed in Guatemala since the year 2000; likewise all other processes like evaluations, calibrations (mappings) and therapy.
