The candidacy for cochlear implant has changed over time and includes people with lesser degrees of hearing loss. Candidacy is based on the pure-tone audiometry thresholds and aided speech testing. The audiogram does not reflect the actual problems faced by an individual with and without hearing aids. The variability in the actual functional hearing and the pure-tone thresholds makes it difficult for the patients whose audiogram is borderline for cochlear implantation and they are not deriving enough benefit from hearing aids.
Retrospective report of the audiological findings of two patients whose cochlear implant funding was refused based on their audiogram. In both instances, they were not deriving benefit from hearing aids and the pure-tone audiometry results were just outside the National Institute for Health and Care Excellence guidelines at 4 kHz.
Cochlear implant candidacy should be individually based and needs to take into account other factors such as work, quality of life, and social impact rather than just adhering to the pure-tone audiometry guidelines. These guidelines should not be considered as strict criteria nor used to deny the benefit of a cochlear implant at the earliest possible opportunity.
人工耳蜗植入的适应证随时间推移而发生了变化,纳入了听力损失程度较轻的人群。适应证基于纯音听力测定阈值和助听后的言语测试。听力图并不能反映佩戴和未佩戴助听器的个体所面临的实际问题。实际功能性听力与纯音阈值之间的差异,使得那些听力图处于人工耳蜗植入临界状态且未从助听器中获得足够益处的患者面临困难。
对两名患者听力检查结果的回顾性报告,这两名患者的人工耳蜗植入资助基于其听力图而被拒绝。在这两个病例中,他们均未从助听器中获益,且纯音听力测定结果仅在4千赫兹时略超出英国国家卫生与临床优化研究所的指南范围。
人工耳蜗植入的适应证应基于个体情况,需要考虑工作、生活质量和社会影响等其他因素,而不仅仅是遵循纯音听力测定指南。这些指南不应被视为严格标准,也不应被用于尽早拒绝人工耳蜗植入带来的益处。
