早年植入人工耳蝸的好處

無論你的孩子年齡多少,他或她均可能收益於人工耳蝸植入。不過,對於學習說話之前已失聰的兒童來說,如果他們在幼時接受植入,成功的機會將會更大1 這些兒童會在他們的頭腦正準備學習語言時接收到聽覺信息。 在許多個案,當患有極重聽覺受損的兒童在年幼時即接受植入,他們的聽力和言語能力可以如聽力正常的兒童一般發育。 在這些個案中,口語的發生幾乎全自然的。2,3

對於曾有聽力而後喪失聽力的兒童,相似的規則亦適用: 失聰的時間越短,就越可能獲益於人工耳蝸。

今日,兒童可以在生命中的第一年即接受植入術。這是一部份是因為手術程序已經改進不少。4 此外,研究顯示兒童在極幼年時接受植入可獲得較好的成效。5,6
