Establishing Genotype–phenotype Correlation in USH2A-related Disorders to Personalize Audiological Surveillance and Rehabilitation
Objective: USH2A-related disorders are characterised by genetic and phenotypic heterogeneity, and are associated with a spectrum of sensory deficits, ranging from deaf blindness to blindness with normal hearing. It has been previously proposed that the presence of specific USH2A alleles can be predictive of unaffected hearing. This study reports the clinical and genetic findings in a group of patients with USH2A-related disease and evaluates the validity of the allelic hierarchy model. Patients...

Contextualizing the Modern Epidemiology of Neurofibromatosis Type 2 in an Era of Heightened Detection of Sporadic Vestibular Schwannoma
Objective: Closely paralleling previous radiologic studies, recent population-based prevalence data suggest sporadic vestibular schwannoma (VS) affects over one in 2,000 adults and up to one in 500 in those aged 70 years or older. Attributable to increased utilization of magnetic resonance imaging and screening protocols for asymmetrical sensorineural hearing loss, the increasing detection rate of sporadic VS fundamentally changes the perception of VS as a whole. The primary objective of the current...

Impact of Auditory-Motor Musical Training on Melodic Pattern Recognition in Cochlear Implant Users
Objective: Cochlear implant (CI) users struggle with tasks of pitch-based prosody perception. Pitch pattern recognition is vital for both music comprehension and understanding the prosody of speech, which signals emotion and intent. Research in normal-hearing individuals shows that auditory-motor training, in which participants produce the auditory pattern they are learning, is more effective than passive auditory training. We investigated whether auditory-motor training of CI users improves complex...

Human Cochlear Nucleus on 7 Tesla Diffusion Tensor Imaging: Insights Into Micro-anatomy and Function for Auditory Brainstem Implant Surgery
Objective: The cochlear nucleus (CN) is the target of the auditory brainstem implant (ABI). Most ABI candidates have Neurofibromatosis Type 2 (NF2) and distorted brainstem anatomy from bilateral vestibular schwannomas. The CN is difficult to characterize as routine structural MRI does not resolve detailed anatomy. We hypothesize that diffusion tensor imaging (DTI) enables both in vivo localization and quantitative measurements of CN morphology. Study Design: We analyzed 7 Tesla (T) DTI images...

High-Dose Furosemide Enhances the Magnetic Resonance Signal of Systemic Gadolinium in the Mammalian Cochlea
Hypothesis: Furosemide alters the permeability of the intrastrial fluid–blood barrier. Background: The cochlear sensory cells are protected by the blood-perilymph and intrastrial fluid–blood barriers, which hinder substances, including gadolinium-based contrast agents (GdCAs), to enter the endolymphatic space. High-dose furosemide causes transient shift of hearing thresholds and morphological changes in stria vascularis. Furosemide is also known to enhance drug-induced ototoxicity. Methods:...

Underwater Endoscopic Repair of Superior Canal Dehiscence
Superior canal dehiscence (SCD) is a bony defect of the superior semicircular canal (SCC). Patients with SCD Syndrome (SCDS) may experience symptoms such as aural fullness, pulsatile tinnitus, hyperacusis, autophony, or pressure or noise-induced vertigo (1–3). The defect can be repaired in various ways, but there is potential for loss of perilymphatic fluid during transmastoid approaches that could result in postoperative sensorineural hearing loss (4–11). We hypothesize that if the procedure were...
