Patients with chronic and severe hearing loss, refractory to nonsurgically-worn devices, may consider use of cochlear implants to regain auditory capability. Cochlear implants consist of surgically emplaced and externally worn components. There are few published examples of the radiographic presentation of these devices appearing in the special needs-based dental literature. This article features a case report and panoramic radiographic examination involving a 67-year-old patient who received bilateral cochlear implants after experiencing a traumatic brain injury and onset loss of hearing. A brief review of strategies for communicating with individuals with severe hearing impairment has also been provided.

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.

Objectives: Healthcare systems contribute significantly to global greenhouse gas emissions through energy consumption and waste generation. This study aims to explore strategies to make cochlear implantation processes more environmentally sustainable and aligned with the United Nations' Sustainable Development Goals.
Methods: We examined various approaches including the use of bio-based and biodegradable materials, sustainable energy solutions, greener anesthetic practices, effective waste separation and recycling in operating rooms, and patient-centered strategies such as reducing travel and promoting early activation and fitting of cochlear implants.

Background And Objective: Speech comprehension in a foreign language under noise conditions presents an increased cognitive demand. For multilingual patients with cochlear implants (PwCI), this poses a particular challenge, as audiological routine diagnostics are typically conducted in the language of the clinical environment. This study investigates speech understanding in noise as well as the subjectively perceived listening effort in PwCI compared to normal-hearing (NH) individuals under both native and nonnative language conditions.

In the recent two decades it became possible to compensate severe-to-profound hearing loss using cochlear implants (CIs). The data from implanted children demonstrate that hearing and language acquisition is well-possible within an early critical period of 3 years, however, the earlier the access to sound is provided, the better outcomes can be expected. While the clinical priority is providing deaf and hard of hearing children with access to spoken language through hearing aids and CIs as early as possible, for most deaf children this access is currently in the second or third year of life.
