It is generally believed that one in every thousand children is profoundly deaf. An understanding of the aetiology of early childhood deafness and timely detection is crucial in rehabilitation of these children. This study analyses the aetiology of early childhood deafness and shows that deafness is more often acquired than inherited. Non-syndromic deafness, especially occurring on its own, usually produces profoundly deaf children and thus there is the need for genetic studies--in the child, laterally, and longitudinally into generations. Meningitis appears to be the commonest cause of acquired deafness, especially if due to pneumococcus. Only 40 of the 80 cases presented before the age of 2 years. It was therefore interesting to note what factors invoked awareness of deafness to facilitate early presentation.
一般认为，每一千名儿童中就有一名是重度失聪。了解幼儿失聪的病因并及时进行检测对于这些儿童的康复至关重要。本研究分析了幼儿失聪的病因，结果表明失聪更多是后天获得而非遗传所致。非综合征性失聪，尤其是单独出现时，通常会导致儿童重度失聪，因此有必要对儿童及其家族进行横向和纵向的基因研究。脑膜炎似乎是后天失聪最常见的原因，尤其是由肺炎球菌引起的。在80例病例中，只有40例在2岁之前就诊。因此，了解哪些因素促使人们意识到失聪以便尽早就诊是很有意思的。
