Cochlear hydrops (or cochlear Meniere's or cochlear endolymphatic hydrops) is a condition of the inner ear involving a pathological increase of fluid affecting the cochlea. This results in swelling that can lead to hearing loss or changes in hearing perception. It is a form of endolymphatic hydrops and related to Ménière's disease. Cochlear ...
In many cases, it is not clear what causes the disorder. Ménière’s attacks occur when there is an increase in endolymphatic volume in the inner ear, causing a temporary leak in the membrane separating the perilymph (potassium poor fluid) and the endolymph (potassium rich fluid). The mix of these two fluids surrounding the vestibular sensory ...
Fluid accumulates in the upper ventricles, causing hydrocephalus. [16] Other causes of congenital hydrocephalus include neural-tube defects, arachnoid cysts, Dandy–Walker syndrome, and Arnold–Chiari malformation. The cranial bones fuse by the end of the third year of life. For head enlargement to occur, hydrocephalus must occur before then.
There are a range of treatment options for sensorineural hearing loss. One of the most common is hearing aids. Traditionally, a hearing aid is a medical device that is fit to a person’s hearing ...

Research has come to the consensus that AIED is the result of antibodies or other immune cells that cause damage to structures of the inner ear such as the cochlea and vestibular system. Of note, AIED is the only known SNHL that responds to medical treatment, but withholding treatment for longer than three months may result in permanent hearing ...
Hearing: Cochlear duct: fluid waves in the endolymph of the cochlear duct stimulate the receptor cells, which in turn translate their movement into nerve impulses that the brain perceives as sound. Balance: Semicircular canals : angular acceleration of the endolymph in the semicircular canals stimulate the vestibular receptors of the endolymph.
Fluid accumulation is the most common cause of conductive hearing loss in the middle ear, especially in children. [3] Major causes are ear infections or conditions that block the eustachian tube , such as allergies or tumors. [ 3 ]
