In this study current indications and the rules for eligibility of patients based on 25 years of experience are presented. \nResults: Indications for cochlear implantation in adults are: 1) bilateral postlingual deafness, 2) bilateral sensorineural hearing loss - in pure tone audiometry &gt; 70 dB HL (average 500-4000 Hz) and in speech audiometry in hearing aids understanding &lt; 50% of words for the intensity of the stimulus 65 dB, in the absence of the benefits of hearing aids, 3) bilateral profound hearing loss for high frequency with good hearing for low frequency, in the absence of the benefits of hearing aids, 4) some cases of asymmetric hearing loss with intensive tinnitus in the deaf ear. An indication in children is bilateral sensorineural hearing loss &gt; 80dB HL confirmed by hearing tests, after about 6 months of rehabilitation with the use of hearing aids. \nDiscussion: Although cochlear implantation is used for more than 40 years, the indications for this treatment underlies constant modifications. They concern the age of eligible patients, implantation in patients with partially preserved hearing, as well as treatment for patients with difficult anatomical conditions. In many countries, bilateral implantations are commonly performed, and more and more centers recommend this treatment in the case of unilateral deafness or asymmetric hearing loss, especially with the accompanying tinnitus in the deaf ear.\n\n<\/jats:p>","DOI":"10.5604\/01.3001.0013.1000","type":"journal-article","created":{"date-parts":[[2019,4,5]],"date-time":"2019-04-05T08:56:09Z","timestamp":1554454569000},"page":"1-5","source":"Crossref","is-referenced-by-count":28,"title":["Current indications for cochlear implantation in adults and children"],"prefix":"10.5604","volume":"73","author":[{"given":"Witold","family":"Szyfter","sequence":"first","affiliation":[{"name":"Klinika Otolaryngologii i Onkologii Laryngologicznej Uniwersytetu Medycznego im.
