In Japan, universal newborn hearing screening has been partly introduced since 2000 in order to discover neonates with congenital deafness, and the average age at discovery was around five months; however, among infants who were not examined by the universal newborn hearing screening, the average age at discovery was around two years. After fitting hearing aids, congenitally deaf infants are educated in a preschool for speech and hearing. If hearing aids are not effective to develop hearing and speech, cochlear implant surgery is performed as modern technology. The outcome of hearing, speech and language after cochlear implantation was excellent. At the age of elementary school enrollment, most of their verbal IQ was considered to be the same as age-matched normal children. Cochlear implant is the most important treatment at present.
在日本，自2000年起部分地区已推行新生儿听力普遍筛查，以发现先天性耳聋的新生儿，其平均确诊年龄约为五个月；然而，在未接受新生儿听力普遍筛查的婴儿中，平均确诊年龄约为两岁。先天性耳聋婴儿在佩戴助听器后，会在学前言语和听力学校接受教育。如果助听器对听力和言语发育无效，则会采用现代技术进行人工耳蜗植入手术。人工耳蜗植入后的听力、言语和语言效果极佳。在小学入学年龄时，他们的大多数言语智商被认为与年龄匹配的正常儿童相同。目前，人工耳蜗植入是最重要的治疗方法。
