Article Synopsis
- The effectiveness of cochlear implants relies on the quality of the prosthetic-neural interface, which is influenced by various technical and anatomical factors like electrode placement, impedance, and the number of active auditory neurons.
- The study models the activation of auditory neurons in cochlear implant users and assesses electrical stimulation efficiency using the auto-NRT algorithm, analyzing data with multivariate regression to account for variations in electrode insertion depth and other factors.
- Findings indicate that NRT thresholds are significantly affected by electrode impedance, electrode scalar placement, and the depth of insertion, which can help gauge the function of auditory neurons in cochlea after implantation.
Improvement of cognitive function after cochlear implantation in elderly patients.

Importance: The association between hearing impairment and cognitive decline has been established; however, the effect of cochlear implantation on cognition in profoundly deaf elderly patients is not known.
Objective: To analyze the relationship between cognitive function and hearing restoration with a cochlear implant in elderly patients.
Design, Setting, And Participants: Prospective longitudinal study performed in 10 tertiary referral centers between September 1, 2006, and June 30, 2009.
Objectives: To compare speech perception outcomes between bilateral implantation (cochlear implants [CIs]) and bimodal rehabilitation (one CI on one side plus one hearing aid [HA] on the other side) and to explore the clinical factors that may cause asymmetric performances in speech intelligibility between the two ears in case of bilateral implantation.
Design: Retrospective data from 2247 patients implanted since 2003 in 15 international centers were collected. Intelligibility scores, measured in quiet and in noise, were converted into percentile ranks to remove differences between centers.
Frequency-place mismatch often occurs after cochlear implantation, yet its effect on speech perception outcome remains unclear. In this article, we propose a method, based on cochlea imaging, to determine the cochlear place-frequency map. We evaluated the effect of frequency-place mismatch on speech perception outcome in subjects implanted with 3 different lengths of electrode arrays.

Study Design: Prospective, longitudinal study performed in 10 tertiary referral centers.
Methods: Ninety-four patients aged 65-85 years with a profound, postlingual hearing loss were evaluated before implantation, at time of activation, and 6 and 12 months after cochlear implantation.
