Cochlear implants have been very successful in restoring partial hearing to profoundly deaf people. Many individuals with implants are now able to communicate and understand speech without lip-reading, and some are able to talk over the phone. Children with implants can develop spoken-language skills and attend normal schools (i.e., schools with normal-hearing children). The greatest benefits with cochlear implantation have occurred in patients who (1) acquired speech and language before their hearing loss, and (2) have shorter duration of deafness. Gradual, but steady, improvements in speech production and speech perception have also occurred in prelingually deafened adults or children.
人工耳蜗在为极重度聋人恢复部分听力方面非常成功。许多植入人工耳蜗的人现在能够在不借助唇读的情况下进行交流和理解言语，有些人还能通过电话交谈。植入人工耳蜗的儿童能够发展口语技能并进入普通学校（即有听力正常儿童的学校）就读。人工耳蜗植入带来的最大益处出现在以下患者身上：（1）在听力丧失前已掌握言语和语言的；（2）耳聋持续时间较短的。对于语前聋的成年人或儿童，其言语表达和言语感知也有逐渐但稳定的改善。
