In recent years there has been an increasing percentage of cochlear implant (CI) users who have usable residual hearing in the contralateral, nonimplanted ear, typically aided by acoustic amplification. This raises the issue of the extent to which the signal presented through the cochlear implant may influence how listeners process information in the acoustically stimulated ear. This multicenter retrospective study examined pre- to postoperative changes in speech perception in the nonimplanted ear, the implanted ear, and both together.

Methods: A prospective cohort study was undertaken identifying all adults who received a thin straight electrode array (TSEA) at the Royal Victorian Eye & Ear Hospital (RVEEH) from 2010 to 2015 and who had a preimplant low frequency pure tone median ≤70 dB HL (n = 63). A retrospective review was completed of the RVEEH database to identify a comparison group who had been implanted with a perimodiolar electrode array, comprising adults implanted between 2004 and 2011 (PM Group) with preimplant hearing equivalent to the TSEA group (n = 70).
Objective: To assess the hearing preservation outcomes in a large group of adult cochlear implant recipients implanted with a thin straight electrode array using atraumatic surgical techniques. Factors affecting hearing preservation will be investigated.
Study Design: Prospective cohort study undertaken at the Royal Victorian Eye and Ear Hospital in Melbourne, Australia from December 2010 to May 2015.
Type 1 diabetes (T1D) incidence has been steadily rising across the globe. Exposure to persistent organic pollutants (POP) has been implied as one potential cause of increased T1D occurrence. Since data regarding the role of POP polychlorinated biphenyl-153 (PCB-153) in autoimmune T1D development in experimental animal models are lacking, this study sought to evaluate the effect of PCB-153 exposure on T1D development in a non-obese diabetic (NOD) mouse model.

Design: Cohort study. Adult CI recipients were recruited based on hearing history and asked to complete the University of Canterbury Music Listening Questionnaire (UCMLQ) to assess each individual's music listening and appreciation.
A multicentre clinical evaluation of paediatric cochlear implant users upgrading to the Nucleus(®) 6 system.

Article Synopsis
- The study aimed to determine if experienced pediatric cochlear implant users would benefit from new technologies in the Nucleus(®) 6 sound processor, specifically noise reduction and automated scene classification, previously shown to help adults.
- Twenty-five pediatric participants were tested on three different sound processor settings to evaluate their speech perception in both quiet and noisy environments over a series of sessions.
- Results indicated no significant difference in word recognition in quiet, but there was a notable improvement in speech perception in noise with the Nucleus 6's default settings, and participants accepted these new technologies well.
Objective: Adult selection criteria for cochlear implantation have been developed based on analysis of the post-operative performance of a large group of postlingually deafened adults. Original criteria published in 2004 were reviewed and amended to reflect outcomes currently being achieved by implant recipients.
Design: Retrospective review of 12-month post-operative speech perception performance of adults implanted at the Eye and Ear Hospital, Melbourne, Australia.
Objective: To evaluate the outcomes after cochlear implantation (CI) in the elderly population, with a particular emphasis on perioperative complications, dizziness, and speech perception outcomes.
Study Design: A retrospective cohort study of elderly cochlear implant patients.
Setting: Tertiary referral center (Cochlear Implant Clinic, Royal Victorian Eye and Ear Hospital, Melbourne).
Objective: Accurate diagnosis of cochlear implant failures is important for management; however, appropriate strategies to assess possible device failures are not always clear. The purpose of this study is to understand correlation between causes of device failure and the presenting clinical symptoms as well as results of in situ integrity testing and to propose effective strategies for diagnosis of device failure.
Study Design: Retrospective case review.
