OBJECTIVES: To study the changes in behavioural and cortical responses over time in a child with single-sided deafness fitted with a cochlear implant (CI). METHODS: Cortical auditory evoked potentials (CAEPs) in noise (+5 dB signal-to-noise ratio) were recorded and auditory skills were assessed using tests of sound localization, spatial speech perception in noise, and self-ratings of auditory abilities (Listening inventory for education, LIFE and Speech, spatial and qualities of hearing questionnaire, SSQ parental version)...

OBJECTIVE: The goal of the present study was to assess the sound quality of a cochlear implant for single-sided deaf (SSD) patients fit with a cochlear implant (CI). BACKGROUND: One of the fundamental, unanswered questions in CI research is "what does an implant sound like?" Conventional CI patients must use the memory of a clean signal, often decades old, to judge the sound quality of their CIs. In contrast, SSD-CI patients can rate the similarity of a clean signal presented to the CI ear and candidate, CI-like signals presented to the ear with normal hearing...

Hearing loss in mature ears can cause functional reorganization of the auditory cortex. The functional reorganization is speculated to negatively affect the outcome of hearing rehabilitation. Therefore, once hearing loss occurs, it is important to provide auditory input before extensive reorganization in the auditory pathways. We investigated the neural plasticity in auditory cortex after single-sided deafness (SSD) in an adult rat model. The animals were divided into two groups: a normal hearing (NH) and the SSD group...

The objective of the present study is to evaluate the effect of hybrid cochlear implantation (hCI) on quality of life (QoL), quality of hearing (QoH), and working performance in adult patients, and to compare the long-term results of patients with hCI to those of patients with conventional unilateral cochlear implantation (CI), bilateral CI, and single-sided deafness (SSD) with CI. Sound localization accuracy and speech-in-noise test were also compared between these groups. Eight patients with high-frequency sensorineural hearing loss of unknown etiology were selected in the study...

We prospectively evaluated the surgical, audiologic, and quality-of-life outcomes in 5 patients-2 men and 3 women, aged 22 to 64 years (mean: 41.8)-who were implanted with the Sophono Alpha 2 MPO Processor. The indications for implantation of this bone-conduction device included recurrent ear canal infections with hearing aids (n = 3), single-sided deafness (n = 1), and patient preference in view of difficulty using a conventional hearing aid (n = 1). In addition to the patient with single-sided deafness, 3 patients had a bilateral mixed hearing loss and 1 had a bilateral conductive hearing loss...

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)...

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)...
