Article Abstract

Hearing loss in older people can cause communication impairments, decreased quality of life, social isolation, depression, and dementia. Cochlear implant surgery is an effective treatment for older patients with hearing loss who cannot achieve satisfactory audiologic outcomes with hearing aids. However, older people have an increased risk of heart disease and often take medications that affect heart rhythm. Herein, we report a case of an 80-year-old woman who underwent cardioversion at 50J after cochlear implant surgery. Electrical impedance before and after cardioversion showed only minor changes without abnormality, and the cochlear implant functioned well. We believe that the electronic circuits of the cochlear implant may have been relatively tolerant to the electrical shock from the external defibrillator. Typically, cardioversion should be avoided in cochlear implant recipients because it may damage the implant. If cardioversion cannot be avoided, we strongly recommend starting cardioversion at the lowest energy level (50 J) and removing the sound processor of the implant during the procedure.

The human auditory system must distinguish relevant sounds from noise. Severe hearing loss can be treated with cochlear implants (CIs), but how the brain adapts to electrical hearing remains unclear. This study examined adaptation to unilateral CI use in the first and seventh months after CI activation using speech comprehension measures and electroencephalography recordings, both during passive listening and an active spatial listening task.

Objectives: In patients with cochlear implants, tools for measuring intracochlear electric environment as well as neural responses to electrical stimulation are widely available. This study aimed to investigate the possible correlation of changes in the responsiveness of the auditory nerve measured by neural response telemetry with changes in the peak and spread of the intracochlear electric field measured by transimpedance matrix (TIM) in patients implanted with straight electrode arrays.

Design: In this retrospective study, we analyzed a cohort of 144 ears of 113 consecutive patients who were implanted with Slim Straight electrode array (Cochlear Ltd.

Recessive variants in TWNK cause syndromes arising from mitochondrial DNA (mtDNA) depletion. Hearing loss is the most prevalent manifestation in individuals with these disorders. However, the clinical and pathophysiological features have not been fully elucidated.

Introduction: Age related hearing loss is in the top ten contributors to the global burden of disease and one of the largest modifiable risk factors for age-related dementia. However, awareness of the consequences of untreated hearing loss is poor and many adults do not seek hearing assessment. Despite World Health Organisation recommendations, no EU country currently has a national adult screening programme.
