有的孩子已经四五岁了(或者更大些),仍然不会讲话,家长常误认为孩子嗓子有病,其实不是。有些聋哑人并非发音器官或大脑的语言中枢有什么病变,而是因为耳聋,听不到声音,以致于无法学习说话。有些患儿虽然已初步学会说话,又因某些原因发生耳聋而丧失了语言能力。聋是因,哑是果。所谓“十聋九哑”就是反映了听力损失与语言障碍之间的因果关系。那么耳聋是怎样发生的?怎样早期发现孩子患了耳聋病? 耳聋的原因大致可分先天性和后天性两种,其中以后天性为最常见,约占百分之七十至八十。先天性耳聋的常见原因有:遗传、父母近亲结婚、妊娠期母体患病或某些药物中毒等。
Some children are four or five years old (or larger), and they still can not speak. Parents often mistakenly think that their children’s voice is sick, but it is not. Some deaf-mutes are not affected by the vocal organs or the language center of the brain, but because they are deaf and unable to hear the sound so that they can not learn to speak. Although some children have initially learned to speak, and for some reason deafness and loss of language skills. Deaf is because dumb is fruit. The so-called “ten deaf and nine dumb ” is a reflection of the causal relationship between hearing loss and language barriers. So how deafness occurs? How early detection of children suffering from deafness? The causes of deafness can be broadly divided into two kinds of congenital and acquired, of which nature is the most common later, accounting for about seventy to eighty percent. Common causes of congenital deafness are: genetic, parental marriage, pregnancy maternal illness or some drug poisoning.
