OBJECTIVES To evaluate the onset of vertigo, hearing loss and tinnitus in Ménière's disease and the associated endolymphatic hydrops (EH) of the inner ear. DESIGN Multicentre evaluation of three patient groups. SETTINGS Disease-specific symptoms were reviewed among referred patients in a tertiary referral hospital in Finland and in members of a Finnish Ménière Association in Finland. The MR...

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 ...

objectives: hearing impairment in children is considered as an important public health problem. auditory function in these children is poor and depends on their hearing aids efficacy and also their ears’ status. hearing aids are very expensive and ear disease deteriorates its performance. therefore detecting the ear disease and offering proper treatment is necessary. the aim of this study is to...

The autoimmune inner ear disease is a clinical syndrome with uncertain pathogenesis that is often associated to rapidly progressive hearing loss that, especially at the early stages of disease, may be at monoaural localization, although more often it is at binaural localization. It usually occurs as a sudden deafness, or a rapidly progressive sensorineural hearing loss. In this study a particul...

ation for the origin of the inner ear disease, the cochlea response, physiology of hearing mechanism and to aid the pharmacological treatment of the inner ear deafness, the oxygen consumption of the stria vascularis and the spiral ligament was studied. The function of the stria vrscularis and the spiral ligament was also studied by electron microscopy. Healthy adult guinea pigs were used in the...

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...
