OBJECTIVES: By extending the indication criteria for cochlear implants (CI), the population of CI candidates increased in age, as well as range and type of hearing loss. This qualitative study identified factors that contributed to seek CI treatment in single-sided deaf individuals and gained insights how single-sided deafness (SSD) and hearing with a CI affect their lives. DESIGN: An open-ended questionnaire and a standardised inventory (IOI-HA) were used. Qualitative data reflecting the reasons to seek CI treatment and the individual experiences after CI switch-on were collected...

The mechanism of tinnitus suppression after cochlear implantation (CI) in single-sided deafness (SSD) is not fully understood. In this regard, by comparing pre- and post-CI quantitative electroencephalography (qEEG), we explored cortical changes relevant to tinnitus improvement. In SSD patients who underwent CI, qEEG data were collected: (1) before CI, (2) 6 months post-operatively with CI-on, and (3) 30 min after CI-off and source-localized cortical activity/functional connectivity analyses were performed...

BACKGROUND: Cochlear implants (CIs) can improve speech-in-noise performance for listeners with unilateral sensorineural deafness. But these benefits are modest and in most cases are limited to head-shadow advantages, with little evidence of binaural squelch. HYPOTHESIS: The goal of the investigation was to determine whether CI listeners with normal hearing or moderate hearing loss in the contralateral ear would receive a larger head-shadow benefit for target speech and noise originating from opposite sides of the head, and whether listeners would experience binaural squelch in the free field in a test involving interfering talkers...

BACKGROUND: Many of the world's population have hearing loss in one ear; current statistics indicate that up to 10% of the population may be affected. Although the detrimental impact of bilateral hearing loss, hearing aids, and cochlear implants upon music appreciation is well recognized, studies on the influence of single-sided deafness (SSD) are sparse. PURPOSE: We sought to investigate whether a single-sided hearing loss can cause problems with music appreciation, despite normal hearing in the other ear...

Cochlear implant (CI) surgery is the standard of care for postlingual deafness in adults. A hearing aid (HA) for the non-implanted ear is normally used if residual hearing is available. There is limited data on bimodal stimulation in elderly patients. We compare the outcome of bimodal stimulation and analyzed the correlation of bimodal benefit and residual hearing in elderly patients. 22 patients≥70 years were implanted with a single-sided CI from 2002 till 2014. 17 patients use a HA on the non-implanted ear (bimodal)...

CONCLUSIONS: The present study revealed that various etiologies are involved in single-sided deafness (SSD), and that the cause of SSD and asymmetrical hearing loss (AHL) differed greatly between congenital/early-onset cases and adult cases. Clarification of the etiology is the first step toward providing appropriate intervention. OBJECTIVES: The study aimed to clarify the etiology of SSD and AHL patients. METHODS: The etiology of a total of 527 SSD or AHL patients who visited Shinshu University Hospital between 2006 and 2016 were analyzed by imaging as well as serological tests for mumps virus, and CMV DNA testing...

Skull base tumors and, in particular, vestibular schwannoma (VS) are among the etiological reasons for single-sided deafness (SSD). Patients with SSD have problems in understanding speech in a noisy environment and cannot localize the direction of sounds. Baha is one of the most frequently used systems for SSD compensation. Out of 38 patients with SSD after retrosigmoid removal of VS who underwent testing with Baha softband, 16 were satisfied and were indicated for Baha implantation. Two surgical approaches have been used-the Nijmegen linear incision technique with subdermal thinning (Group I, implant BI300) and fast surgery technique without subdermal thinning (Group II, implant BIA400)...

Treatment with cochlear implants (CIs) in single-sided deaf individuals started less than a decade ago. CIs can successfully reduce incapacitating tinnitus on the deaf ear and allow, so some extent, the restoration of binaural hearing. Until now, systematic evaluations of subjective CI benefit in post-lingually single-sided deaf individuals and analyses of speech intelligibility outcome for the CI in isolation have been lacking. For the prospective part of this study, the Bern Benefit in Single-Sided Deafness Questionnaire (BBSS) was administered to 48 single-sided deaf CI users to evaluate the subjectively perceived CI benefit across different listening situations...

The objective of the study was to evaluate the quality of life and benefit in patients with single-side deafness before and 1 year after cochlear implantation. In a prospective observational study design, ten adult patients with single-sided deafness undergoing cochlear implantation were included. All patients had on the implantation side no speech discrimination with normal hearing aids. The contralateral side was normal or marginal hearing loss. For determining the subject benefit from cochlear implantation, each patient answered standardized questionnaires directly before implantation and 1 year after...

J F Liu, J S Dai, N Y Wang
In patients with single-sided deafness (SSD), the interaural time difference and the interaural level difference signals are insufficient or missing, which result in the lack of sound localization ability and the decrease of speech comprehension in the noise environments. SSD can also cause the morphological and functional changes of the central auditory system, resulting in auditory deprivation. In early stage of the development, the auditory center is more susceptible to ambient environment and auditory inputs...

OBJECTIVES: Bone-anchored hearing aids (BAHAs) have been known to partially restore some of the functions lost in subjects with single-sided deafness (SSD). Our aims in this systemic review were to analyze the present capabilities of BAHAs in the context of SSD, and to evaluate the efficacy of BAHAs in improving speech recognition in noisy conditions, sound localization, and subjective outcomes. DESIGN: A systematic search was undertaken until August 2015 by two independent reviewers, with disagreements resolved by consensus...

We have recently proposed a binaural cochlear implant (CI) sound processing strategy inspired by the contralateral medial olivocochlear reflex (the MOC strategy) and shown that it improves intelligibility in steady-state noise (Lopez-Poveda et al., 2016, Ear Hear 37:e138-e148). The aim here was to evaluate possible speech-reception benefits of the MOC strategy for speech maskers, a more natural type of interferer. Speech reception thresholds (SRTs) were measured in six bilateral and two single-sided deaf CI users with the MOC strategy and with a standard (STD) strategy...
