The HiFocus Mid-Scala (MS) electrode array has recently been introduced onto the market. This precurved design with a targeted mid-scalar intracochlear position pursues an atraumatic insertion and optimal distance for neural stimulation. In this study we prospectively examined the angular insertion depth achieved and speech perception outcomes resulting from the HiFocus MS electrode array for 6 months after implantation, and retrospectively compared these with the HiFocus 1J lateral wall electrode array. The mean angular insertion depth within the MS population (n = 96) was found at 470°...

Single-sided deaf subjects with a cochlear implant (CI) provide the unique opportunity to compare central auditory processing of the electrical input (CI ear) and the acoustic input (normal-hearing, NH, ear) within the same individual. In these individuals, sensory processing differs between their two ears, while cognitive abilities are the same irrespectively of the sensory input. To better understand perceptual-cognitive factors modulating speech intelligibility with a CI, this electroencephalography study examined the central-auditory processing of words, the cognitive abilities, and the speech intelligibility in 10 postlingually single-sided deaf CI users...

The deteriorating ability to communicate has a negative impact on quality of life in the aging population. Cochlear implantation is increasingly used to treat hearing impairment and to restore the ability to communicate. Here, in a sample of 79 adults (70 years and older), we explored the effect of cochlear implantation on the health-related quality of life via the Nijmegen Cochlear Implant Questionnaire, auditory performance for speech recognition comparing scores on the Freiburg Monosyllabic Test and Oldenburg Inventory and tinnitus-related distress using the German version of the Tinnitus Questionnaire...

Cochlear implantation has a significant impact on patients' social life, performance of activities, and self-esteem. The objective of this retrospective study was to assess the health-related quality of life of cochlear implant users aged under and over 60 years by a self-report using the Glasgow Health Status Inventory and the Abbreviated Profile of Hearing Aid Benefit. It was observed that quality of life values increased very rapidly straight after implantation regardless of age. Bilateral cochlear implant users showed better results in environments with background noise and in a reverberant room than unilateral cochlear implant users...

Hearing impairment in the elderly is usually treated with conventional hearing aids; however, a large number of older people do not achieve sufficient speech recognition with hearing aids. The aim of the study was to describe speech perception with hearing aids in comparison to pure-tone hearing loss and maximum speech recognition scores for phonemically balanced words. Data from 392 hearing aid users with different degrees of hearing loss were evaluated retrospectively. In particular, pure-tone thresholds, the maximum monosyllabic word score, and the monosyllabic word score in quiet at conversational level with a hearing aid were analysed...

The number of cochlear implant (CI) users is increasing annually, resulting in an increase in the workload of implant centers in ongoing patient management and evaluation. Remote testing of speech recognition could be time-saving for both the implant centers as well as the patient. This study addresses two methodological challenges we encountered in the development of a remote speech recognition tool for adult CI users. First, we examined whether speech recognition in noise performance differed when the steady-state masking noise was presented throughout the test (i...

The study aim was to determine the benefit of cochlear implantation and hearing aids in older adults diagnosed with hearing loss and to evaluate the index of depression, anxiety and quality of life after such treatments. A retrospective cohort comprised 117 patients older than 65 years and diagnosed with moderate to profound hearing loss who were included and classified into 2 groups (treated vs. non-treated). A battery of tests including auditory (pure-tone average, disyllabic words in quiet at 65 dB SPL) and findings from a series of questions relevant to quality of life were compared between both groups...

Cognitive impairment and dementia are characterized by a progressive and devastating reduction in most cognitive abilities, functional independence, and social relationships. Dementia represents a substantial financial burden on society, one that is comparable to the financial burden of heart disease and cancer. Due to its insidious onset, cognitive impairment can be clinically silent for several years; therefore, diagnosis occurs late in the disease process, and treatment becomes almost useless. The identification of predictors of dementia may help identify the pathophysiological mechanisms underlying the disease and lead to the development of a more effective medical diagnosis and therapy, and thus an early treatment...

To contribute to a better understanding of the etiology in age-related hearing loss, we carried out a cross-sectional study of 3,315 participants (aged 52-99 years) in the Rotterdam Study, to analyze both low- and high-frequency hearing loss in men and women. Hearing thresholds with pure-tone audiometry were obtained, and other detailed information on a large number of possible determinants was collected. Hearing loss was associated with age, education, systolic blood pressure, diabetes mellitus, body mass index, smoking and alcohol consumption (inverse correlation)...

Transient receptor potential vanilloid (TRPV) 4 is a nonselective cation channel expressed in sensory neurons such as those in the dorsal root and trigeminal ganglia, kidney, and inner ear. TRPV4 is activated by mechanical stress, heat, low osmotic pressure, low pH, and phorbol derivatives such as 4α-phorbol 12,13-didecanoate (4α-PDD). We investigated the expression of TRPV4 in rat vestibular ganglion (VG) neurons. The TRPV4 gene was successfully amplified from VG neuron mRNA using reverse-transcription polymerase chain reaction...

Tissue trauma is a frequent complication of cochlear implantation (CI) surgery, but the relationship between intracochlear trauma, electrode insertion forces, and surgeons' ability to perceive these forces is poorly understood. In this study, we simulated CI surgery using a benchtop apparatus to repeatedly apply small forces to the subjects' hands while reducing the variability in their hand movements. We used a psychophysical testing procedure to estimate the force perception thresholds of 10 otologic surgeons and found a median threshold of 20...

Transcranial attenuation (TA) of bone-conducted sound has a high degree of variability by frequency and subject, which may play a role in the objective benefit of individuals with single-sided deafness (SSD) treated with a bone-anchored implant (BAI). This study sought to determine whether TA is predictive of benefit in individuals with SSD who receive a BAI. Adult, English-speaking patients with unilateral profound sensorineural hearing loss who underwent a BAI evaluation were included for study. Absolute TA values were consistent with previously published reports...
