非人工耳蜗植入者的临床和行为描述： 20年回顾性描述性分析

Although cochlear implants (CIs) effectively restore hearing, device abandonment ('non-use') remains a critical challenge limiting long-term auditory rehabilitation. This study aimed to evaluate the prevalence, clinical and radiological characteristics, and patient-reported reasons for CI non-use, comparing pre-lingually and post-lingually deafened individuals to inform long-term retention strategies.
