Multichannel auditory brainstem implants (ABI) are currently indicated for patients with neurofibromatosis type II (NF2) involving both vestibulocochlear nerves. The ABI helps bypass the damaged cochlear nerves and restores a level of auditory sensation via the electrical stimulation of the cochlear nucleus. The implant is usually placed in the lateral recess of the fourth ventricle at the time of tumor resection to stimulate the cochlear nucleus. We report a case of ABI done on a 15-year-old girl with bilateral vestibular schwannomas.

Hearing loss occurs prior to thrombocytopenia in both mice and humans with DFNA1.
FASEB J

Laboratory of Molecular Pharmacology, Biosignal Research Center, Kobe University, Kobe, Japan.
DFNA1 (deafness, nonsyndromic autosomal dominant 1), initially identified as nonsyndromic sensorineural hearing loss, has been associated with an additional symptom: macrothrombocytopenia. However, the timing of the onset of hearing loss (HL) and thrombocytopenia has not been investigated, leaving it unclear which occurs earlier. Here, we generated a knock-in (KI) DFNA1 mouse model, diaphanous-related formin 1 (DIA1), in which Aequorea coerulescens green fluorescent protein (AcGFP)-tagged human DIA1(p.

Objective: The aim of this study was to assess hearing level of preschoolers with delayed speech in order to detect any underlying hearing loss Methods: In this research we targeted preschool children with speech delay, who have not been previously diagnosed with any medical or psychological illnesses. A total of 54 preschool speech-delayed children were audiologically assessed in our clinic in the past year. The age at time of referral ranged from two to 7.

Sexually mature females of multiple mammalian species were previously reported to have increased peripheral auditory sensitivity, often measured as higher auditory brainstem response (ABR) wave I amplitude compared to males. Here, we determined potential hormonal and genetic (i.e.

Objective: To describe and compare the latencies and amplitudes of Mismatch Negativity between children with and without Developmental Dyslexia.
Methods: Cross-sectional and comparative study, consisting of a study group of 52 children with Developmental Dyslexia and a control group of 52 children with typical development, matched by age and sex, aged between 9 years and 11 years and 11 months of both sexes. All participants underwent Otoscopy, Acoustic Immittance Measurements, Pure Tone Audiometry, Speech Audiometry, Brainstem Auditory Evoked Potential and Mismatch Negativity.
A Neuron-Like Cellular Model for Severe Tinnitus Associated with Rare Variations in the ANK2 Gene.

Tinnitus is the perception of sound without an external source, often associated with changes in the auditory pathway and different brain regions. Recent research revealed an overload of missense variants in the ANK2 gene in individuals with severe tinnitus. ANK2, encoding ankyrin-B, regulates axon branching and inhibits microtubule invasion.
