Koxlear implant — og‘ir va chuqur sensorinevral eshitish yo‘qotilishida qo‘llanadigan implantatsion eshitish tizimi bo‘lib, shikastlangan yoki yetarli faoliyat ko‘rsatmayotgan koklear tuzilmalarni qisman chetlab o‘tib, eshitish nervini elektr stimulyatsiyasi orqali qo‘zg‘atadi. Koxlear implant tovushni oddiy kuchaytiruvchi vosita emas. Tashqi mikrofon tovushni qabul qiladi, nutq protsessori signalni qayta ishlaydi, uzatuvchi qism esa kodlangan signalni teri ostidagi implantga yetkazadi; elektrodlar koklea ichida elektr stimulyatsiya hosil qiladi. Natijada eshitish nervi orqali markaziy eshitish tizimiga axborot uzatiladi. Implantatsiyaning samarasi eshitish yo‘qotilishining turi va davomiyligi, implantatsiya yoshi, eshitish nervi va ichki quloq anatomiyasi, avvalgi eshitish tajribasi, qurilmadan muntazam foydalanish hamda reabilitatsiya bilan bog‘liq. Ayniqsa bolalarda implantatsiyadan keyingi eshitish-nutqiy reabilitatsiya til va kommunikativ rivojlanish uchun muhim hisoblanadi.
