According to data from the Brazilian Institute of Geography and Statistics, the elderly population grew 47.8% in the last decade in Brazil. A portion of this population has severe and/or profound hearing loss and do not benefit from conventional hearing aids. Thus, the use of cochlear implant is required.
To analyze the benefits of cochlear implants in the elderly based on the comparison of primary auditory thresholds before and after the operation, discrimination of sentences in speech and in talking on the telephone.
Retrospective cohort study, analyzing medical records from patients aged over 60 years, users of cochlear implant for at least 1 year.
Fourteen medical records were analyzed. Mean age of patients was 63.07 years. The mean pure tone thresholds between 500Hz, 1kHz, 2kHz and 4kHz before the implantation was 113dBHL. None of the patients, before operation, could discriminate sentences in open sets and only 3 scored 17% in closed sets sentence recognition. After one year of implantation, the mean sound field thresholds reached 34dBHL, and open set sentences recognition of 93.57%, while 71% of the patients had become able to have a conversation on the telephone.
The elderly users of cochlear implant showed important outcomes, with significant improvement in understanding in the open set and in using the telephone.
根据巴西地理统计局的数据，在过去十年中，巴西的老年人口增长了 47.8%。这部分人口有严重和/或深度听力损失，无法从传统助听器中受益。因此，需要使用人工耳蜗。
通过比较手术前后的主要听觉阈值、言语和电话交谈中的句子辨别能力，分析人工耳蜗植入对老年人的益处。
回顾性队列研究，分析了至少使用人工耳蜗 1 年的 60 岁以上患者的病历。
分析了 14 份病历。患者平均年龄为 63.07 岁。植入前 500Hz、1kHz、2kHz 和 4kHz 的纯音阈值平均为 113dBHL。在手术前，没有患者能够辨别开放式句子，只有 3 名患者在封闭式句子识别中得分 17%。植入一年后，平均声场阈值达到 34dBHL，开放式句子识别率为 93.57%，71%的患者能够在电话上进行交谈。
人工耳蜗植入的老年使用者表现出重要的结果，在开放式理解和使用电话方面有显著改善。
