The objectives of this study were to assess: (i) patient expectations met as a measure of outcome in early-deafened, late-implanted (non-traditional) cochlear implant recipients and (ii) pre-implantation predictive factors for postoperative speech perception. The notes of 13 recipients were retrospectively reviewed. The mean age at onset of profound deafness was 1.5 years (range 0-6). The mean age at implantation was 37 years (range 22-51 years). Patient expectations were assessed pre-operatively and 1 year after implantation...

In a subpopulation of patients, tinnitus can be modulated by movements of the jaw or head and neck due to complex somatosensory-auditory interactions. In some of these subjects, tinnitus could be related to an underlying temporomandibular (TMJ) or craniocervical (NECK) dysfunction that, if correctly identified, could streamline treatment and increase chances of tinnitus improvement. However, it is still unclear whether somatic modulation of tinnitus could be used as a screening tool for identifying such patients...

A key feature of superior canal dehiscence (SCD) syndrome is supranormal hearing of body sounds. The aim of the present study was to quantify this phenomenon and to ascertain whether auditory sensitivity to body vibrations can distinguish SCD patients. Hearing thresholds in response to vibration at the vertex, at the spinous process of the 7th cervical vertebra, and at the medial malleolus were tested in 10 SCD patients and 10 controls. Both patients and controls had insert earphones in both ears. The insert in the test ear was blocked while masking was presented to the other ear...

BACKGROUND: Delivery of therapeutic agents directly through the round window (RW) offers promise for treating sensorineural hearing loss. However, hearing loss can result from the surgical approach itself, and the reasons for this are poorly understood. We examined the hearing loss following the 3 major steps involved with the RW approach to access the mouse cochlea: bullostomy, RW puncture, and RW injection. METHODS: Twenty-one adult CBA/J mice underwent bullostomy alone, 10 underwent RW puncture, and 8 underwent RW injection with PBS with 5% glycerol...

The active middle ear implant Vibrant Soundbridge© provides a variety of coupling modalities of the floating mass transducer (FMT) to various structures of the ossicular chain and the round window. A retrospective analysis was performed on 125 subjects (n = 137 ears) (1) to compare the efficacy of the different FMT coupling modalities with increasing degree of hearing loss, (2) to compare the performance in speech outcome and the effective gain between the coupling types, and (3) to evaluate the risk of additional hearing loss of each coupling procedure...

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...

OBJECTIVE: To report the speech performance and sound localization in adult patients 5 years after bilateral simultaneous cochlear implantation and to evaluate the change in speech scores between 1 and 5 years. DESIGN: In this prospective multicenter study, 26 patients were evaluated 5 years after implantation using long straight electrode arrays (MED-EL Combi 40+, standard electrode array, 31 mm). Speech perception was measured using disyllabic words in quiet and noise, with the speech coming from the front and a cocktail party background noise coming from 5 loudspeakers...

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...

The objective of this study was to examine how age and implanted ear contribute to functional outcomes with cochlear implantation (CI). A retrospective review was performed on 96 adults who underwent unilateral CI. Older adults with right-ear implants had higher Hearing in Noise Test (HINT) scores at 1 year by 10.3% (p = 0.06). When adjusted to rationalized arcsine units (rau), right-ear HINT scores in older adults were higher by 12.1 rau (p = 0.04). Older adults had an 8.9% advantage on the right side compared to the left in post- versus preimplant scores for consonant-vowel nucleus-consonant words (p = 0...
