Objective: Our primary aim was to determine, in a simulation of a crowded restaurant, the value to speech understanding of (i) a unilateral cochlear implant (CI), (ii) a CI plus CROS (contralateral routing of signals) aid system and (iii) bilateral CIs when tested with and without beamforming microphones.
Design: The listeners were 7 CI listeners who had used bilateral CIs for an average of 9 years. The listeners were tested with three device configurations (bilateral CI, unilateral CI + CROS, and unilateral CI), two signal processing conditions (without and with beamformers) and with speech either from +90°, -90°, or from the front.

Previous studies have reported that exposure to lead and cadmium can damage the inner ear receptor, which perceives high-frequency sounds. However, few studies have used the pure-tone average (PTA), including high-frequency ranges, for the estimation of hearing loss caused by lead and cadmium exposure. We estimated hearing loss using the PTA test, in low-frequency, speech frequency, and high-frequency ranges and compared the differences in the results using 3 PTA calculation methods. Read More

Endocytic sorting of activated receptor tyrosine kinases (RTKs), alternating between recycling and degradative processes, controls signal duration, location, and surface complement of RTKs. The Microtubule (MT) plus-end tracking proteins (+TIPs) play essential roles in various cellular activities including translocation of intracellular cargo. However, mechanisms through which RTKs recycle back to the plasma membrane following internalisation in response to ligand remain poorly understood. Read More

Background: Previous studies on the impact of wait times for endoscopic sinus surgery (ESS) in medically recalcitrant chronic rhinosinusitis (rCRS) have not examined its influence on the 5 distinct symptoms domains of the 22-item Sino-Nasal Outcome Test (SNOT-22), and have not applied evidence-based surgical indications. Our primary study objective was to investigate the impact of ESS wait times on postoperative SNOT-22 global and symptom domain scores in patients with rCRS deemed "appropriate" surgical candidates.

ATP2B2 encodes the PMCA2 Ca pump that plays an important role in maintaining ion homeostasis in hair cells among others by extrusion of Ca from the stereocilia to the endolymph. Several mouse models have been described for this gene; mice heterozygous for loss-of-function defects display a rapidly progressive high-frequency hearing impairment. Up to now ATP2B2 has only been reported as a modifier, or in a digenic mechanism with CDH23 for hearing impairment in humans. Read More

The inner ear and its two subsystems, the vestibular and the auditory system, exemplify how the identification of distinct cellular or anatomical elements ahead of elucidating their function, leads to a medley of anatomically defined and recognition oriented names that confused generations of students. Past attempts to clarify this unyielding nomenclature had incomplete success, as they could not yet generate an explanatory nomenclature. Building on these past efforts, we propose a somewhat revised nomenclature that keeps most of the past nomenclature as proposed and follows a simple rule: Anatomical and explanatory terms are combined followed, in brackets, by the name of the discoverer (see Table 1).

Mechanosensory hair cells of the inner ear transduce auditory and vestibular sensory input. Hair cells are susceptible to death from a variety of stressors, including treatment with therapeutic drugs that have ototoxic side effects. There is a need for co-therapies to mitigate drug-induced ototoxicity, and we showed previously that induction of heat shock proteins (HSPs) protects against hair cell death and hearing loss caused by aminoglycoside antibiotics in mouse.

Background: Pure-tone audiometry is essential in diagnosing clinical hearing loss. Masking of the nontest ear is mandatory for determining accurate hearing thresholds in the presence of asymmetrical levels between the two ears and for ascertaining the presence of a conductive hearing loss. Paradoxically, over masking occurs when the intensity of the required masking noise to the contralateral ear is such that it exceeds interaural cranial attenuation by an amount sufficient to mask the test ear.

Objectives: Functional outcomes following cochlear implantation have traditionally been focused on word and sentence recognition, which, although important, do not capture the varied communication and other experiences of adult cochlear implant (CI) users. Although the inadequacies of speech recognition to quantify CI user benefits are widely acknowledged, rarely have adult CI user outcomes been comprehensively assessed beyond these conventional measures. An important limitation in addressing this knowledge gap is that patient-reported outcome measures have not been developed and validated in adult CI patients using rigorous scientific methods.

Using transgenic fluorescent reporter mice in combination with an established tissue clearing method, we detail heretofore optically opaque regions of the spiral lamina and spiral limbus where the auditory peripheral nervous system is located and provide insight into changes in cochlear vascular density with ageing. We found a relatively dense and branched vascular network in young adults, but a less dense and thinned network in aged adults. Significant reduction in vascular density starts early at the age of 180 days in the region of the spiral limbus (SL) and continues into old age at 540 days. Read More
