Abstract

Objective: The current study aimed to evaluate cochlear reimplantation rate, causes, and audiological outcomes in a large group of patients in a multicenter study.

Methods: This retrospective study was conducted on patients with cochlear reimplantation surgeries between 2000 and 2022 in five academic referral centers. The rate and reasons for cochlear reimplantation surgeries were evaluated. The auditory performance and speech production outcomes were compared before and after cochlear reimplantation surgeries.

Results: Of 9,287 primary cochlear implantation surgeries, 186 reimplantations were performed (a cochlear reimplantation rate of 2%). The highest risk of reimplantation was found 2 to 4 years after primary implantation. Device failure was the main reason for cochlear reimplantation (81.2%). The categories of auditory performance and speech intelligibility rating scores were unchanged or improved in 57 out of 59 patients (96.6%), and 55 out of 59 patients (93.2%), respectively.

Conclusion: The cochlear reimplantation rate seems to be relatively low, with the cause of device failure in most cases. While the highest risk of reimplantation happened during the first four years after primary surgery, regular follow-ups are necessary, particularly during this time. The audiological outcomes do not worsen after reimplantation in most patients, and some children may experience some improvements.

人工耳蜗再植率、原因和结果：一项多中心研究。

目的：在一项多中心研究中，本研究旨在评估大量患者的人工耳蜗再植率、原因和听力学结果。方法：对5家学术转诊中心2000 ~ 2022年间行人工耳蜗再植手术的患者进行回顾性研究。分析了人工耳蜗再植手术的发生率及原因。比较人工耳蜗再植术前后的听觉表现和言语功能。结果：9287例人工耳蜗植入术中，再植186例（再植率2%）。再次植入术的最高风险出现在首次植入术后的2 - 4年。器械失效是人工耳蜗再植的主要原因（81.2%）。59例患者中57例（96.6%）和59例患者中55例（93.2%）的听觉表现和言语清晰度评分类别不变或改善。结论：人工耳蜗再植率相对较低，以人工耳蜗装置失效为主。虽然再植的最高风险发生在初次手术后的头四年，但定期随访是必要的，特别是在这段时间。大多数患者的听力学结果在再植后不会恶化，一些儿童可能会有一些改善。

期刊介绍： Cochlear Implants International was founded as an interdisciplinary, peer-reviewed journal in response to the growing number of publications in the field of cochlear implants. It was designed to meet a need to include scientific contributions from all the disciplines that are represented in cochlear implant teams: audiology, medicine and surgery, speech therapy and speech pathology, psychology, hearing therapy, radiology, pathology, engineering and acoustics, teaching, and communication. The aim was to found a truly interdisciplinary journal, representing the full breadth of the field of cochlear implantation.
