Objective: This study aimed to assess the static balance function in deaf adolescents with cochlear implants.
Methods: We included 24 adolescents who had received unilateral cochlear implantation for at least 5 years. Each subject underwent stabilometry testing under 4 different conditions: (A) firm surface with eyes open; (B) firm surface with eyes closed; (C) foam pad with eyes open; and (D) foam pad with eyes closed. All of them received tests with their cochlear implant turned on and off. Another 24 age- and sex-matched adolescents with normal hearing were tested in the same way for comparison. Sway velocity and circular area were measured and analyzed.
Results: The mean sway velocity of the cochlear implant group under conditions A-D was 1.68, 1.98, 2.36, and 5.25 cm/s, respectively, and the mean circular area of the cochlear implant group under conditions A-D was 7.39, 6.68, 12.21, and 34.27 cm(2), respectively. Both of the parameters showed statistical significance between the cochlear implant group and the normal hearing group for conditions A, C and D (p<0.05). Furthermore, there was no significant balance function change among cochlear implant group with their implant "on" and "off".
Conclusions: This study showed that the static balance function in adolescents with long-term use of cochlear implants was worse than those of normal hearing peers. The difference between the cochlear implant group and normal hearing group was the highest when both visual and somatosensory inputs were disrupted. The postural stability was similar whether or not the cochlear implant was activated.

Objectives: Hearing loss is associated with increased cognitive decline and incident dementia in older adults. Given the rapidly rising incidence of dementia, management of modifiable risk factors such as hearing loss, is essential to mitigate the impact on the individual and society in general. In this narrative review, we discuss the current state-of-art with respect to studying cognitive function before and after cochlear implantation in the elderly population.

Purpose: Prelingual deaf children with cochlear implants show lower digit span test scores compared to normal-hearing peers, suggesting a working memory impairment. To pinpoint more precisely the subprocesses responsible for this impairment, we designed a sequence reproduction task with varying length (two to six stimuli), modality (auditory or visual), and compressibility (sequences with more or less regular patterns). Results on 22 school-age children with cochlear implants and 21 normal-hearing children revealed a deficit of children with cochlear implants only in the auditory modality.

Objective: Early diagnosis, intervention and consistent follow-up of hearing loss is of great importance in children, given the broad impact of untreated childhood hearing loss. Currently, no hearing-specific QOL proxy questionnaire exists for preschool children with hearing loss in the Dutch language. Therefore, the aim of this study was to translate and validate the Preschool HEAR-QL questionnaire into Dutch.

Objectives: Cochlear implant (CI) user functional outcomes are challenging to predict because of the variability in individual anatomy, neural health, CI device characteristics, and linguistic and listening experience. Machine learning (ML) techniques are uniquely poised for this predictive challenge because they can analyze nonlinear interactions using large amounts of multidimensional data. The objective of this article is to systematically review the literature regarding ML models that predict functional CI outcomes, defined as sound perception and production.

Objective: The aim of this study is to detail and evaluate the surgical procedure for perilymph sampling from the cochlear apex in the Mongolian gerbil.
Design: Perilymph sampling from the cochlear apex was performed one to three time in 12 male gerbils aged 8 to 12 months via the submandibular route. 11 of them were previously implanted with intracochlear implants loaded with dexamethasone and placed in the scala tympani, the 12th was used to collect control samples.
