Early detection of deafness is important for rehabilitation and diagnosis. In spite of prompt treatment the effects of deafness on language and learning can be devastating. The scope of hearing aids is advancing all the time, but the severely deaf child will never be able to obtain anything but rudimentary auditory input. As deaf children and their parents become more aware of the risks of genetic deafness, an aetiology should be established wherever possible.
早期发现耳聋对于康复和诊断至关重要。尽管进行了及时治疗，但耳聋对语言和学习的影响可能是毁灭性的。助听器的功能一直在进步，但重度耳聋儿童除了获得基本的听觉输入外，永远无法获得更多。随着聋儿及其父母越来越意识到遗传性耳聋的风险，应尽可能确定病因。
