meniere’s disease is the disorder of inner ear characterized by vertigo, tinnitus and sensorineural hearing loss. the vestibular evoked myogenic potential (vemp) test could be useful in the analysis of saccular function, and diagnosis of meniere’s disease. in this study, we’ve analyzed the saccular function, using vemp test in different groups of meniere’s disease. patients were categorized as ...

Bone conduction describes the mechanisms that produce a hearing sensation when the skull bones are subjected to vibration. Multiple components and pathways have been suggested to contribute to total bone-conducted sound. They include outer-ear cartilaginous wall compression, middle-ear inertia, fluid inertia, cochlear capsule compression and soft-tissue conduction. Due to the complexity of the ...

Background. Thanks to the development of technology and new surgical approaches, it has become possible perform cochlear implantation (CI) in patients with malformations inner ear. The experience this type rehabilitation more than 15 years Russian practice 20 world. Unfortunately, COVID-19 pandemic added not only one cause deafness, but also etiological factor complications. purpose paper is de...

Mutations and deletions in the gene or upstream of encoding POU3F4 transcription factor cause X-linked progressive deafness DFNX2 additional neurodevelopmental disorders humans. Hearing loss can be purely sensorineural mixed, that is, with both conductive components. Affected males show anatomical abnormalities inner ear, which are jointly defined as incomplete partition type III. Current appro...

Transtympanic gentamicin administration has become a popular modality in the treatment of Ménière's disease. This modality and other inner-ear medical therapy are gaining increased clinical and scientific attention. We previously described the kinetics and effects of gentamicin uptake into the inner ear after delivery of the medicine into the middle ear using a variety of different techniques a...

The inner ear, composed of the cochlea and the vestibule, is a specialized sensory organ for hearing and balance. Although the inner ear has been known as an immune-privileged organ, there is emerging evidence indicating an active immune reaction of the inner ear. Inner ear inflammation can be induced by the entry of proinflammatory molecules derived from middle ear infection. Because middle ea...

HYPOTHESIS That a theoretical basis for quantifying drug distribution in the inner ear with local applications can be established. BACKGROUND As methods of local drug delivery to the inner ear gain wider clinical acceptance it becomes important to establish how drugs are distributed in the ear as a function of time and for different delivery methods. METHODS The time course of gentamicin co...

We have demonstrated that the phenotype of the mouse mutant sex-linked fidget ( slf ) is caused by developmental malformations of the inner ear that result in hearing loss and vestibular dysfunction. Recently, pilot mapping experiments suggested that the mouse Brn4 / Pou3f4 gene co-segregated with the slf locus on the mouse X chromosome. These mapping data, in conjunction with the observation t...

Transcranial cerebral sonography (TCCS) is a noninvasive technique that allows the clinician to detect abnormal intracranial-inner-ear fluid interactions in terms of nanoliter tympanic membrane displacements. The displacements recorded in TCCS are evoked either by the acoustic stapedius reflex or spontaneous movements generated by intracranial cardiovascular or by respiratory pressure waves tra...
