Hearing aid trials in pediatric cochlear implantation
Medical Studies/Trials
Published: Wednesday, 19-Sep-2007
Children with severe to profound hearing loss under evaluation for cochlear implantation have traditionally been given a three to six month hearing aid trial to verify that they don't receive sufficient audiometric and speech benefit from hearing aids before proceeding with cochlear implantation.
But a new study presented at the 2007 AAO-HNSF Annual Meeting & OTO EXPO has shown in the sample pediatric population that children with severe to profound sensorineural hearing loss that had a hearing aid trial derived minimal benefit from it. Researchers followed 85 patients (nine months to 14 years), 58 of whom were implanted with a hearing aid. Only six patients undergoing the trial were able to hear conversational speech sounds with the hearing aids and none of the children developed normal speech and language. After cochlear implantation, there were dramatic improvements in speech and language abilities in all children.
Study results suggest that in children born with deafness, there does not appear to be a reason to delay cochlear implantation for the sole purpose of completing a trial of hearing aids, as is currently recommended by the FDA. Risks in delaying cochlear implantation include speech and language deficits.

儿童人工耳蜗植入术前的助听试验
患有重度至极重度听力损失的患儿在工耳蜗植入术前评估中，目前常规在术前被给予3到6个月的时间进行助听试验，以确定他们不会从助听器中获得足够的听力及言语方面的益处。
但是发布在2007年美国耳鼻咽喉头颈外科年会及博览会上的一项新的儿童群体抽样调查研究表明：患有重至极重度感音神经性听力损失的患儿从助听试验中所得到的益处微乎其微。研究者们跟踪随访了85名患儿（年龄9个月至14岁），其中有58名患儿在人工耳蜗植入术前进行了助听试验。在这些接受助听试验的患儿中仅有6名佩戴助听器后可以听到言语谈话的声音，并且没有一个患儿拥有正常的言语及语言发育。在人工耳蜗植入后，所有患儿的言语及语言能力均得到了极大的提高。
研究结果提示，先天性听力障碍的患儿没有理由仅仅为了完成助听试验而推迟人工耳蜗植入的时机，正如FDA当前所推荐的做法那样。延迟人工耳蜗植入的危险包括言语及语言发育不足。
背景：目前在人工耳蜗植入流行的观点是要在术前给患儿佩戴3-6月的助听器，只有当助听器无效的情况下，才考虑进行人工耳蜗植入。本文的观点认为患儿从术前的助听器的佩戴试验中不能得到明显的益处，且有可能因为进行此项试验而延迟了患儿进行人工耳蜗植入的时机，可能对患儿的言语及语言发育产生不利的影响。但目前关于此方面的研究尚不多见，因此就目前而言尚难以断定这一观点就是正确的，还有待于进一步的循证医学的研究。
