Objective: Intravenous contrast agent enhanced, high-resolution magnetic resonance imaging of the inner ear (iMRI) confirmed that patients with Menière's disease (MD) and vestibular migraine (VM) could present with endolymphatic hydrops (EH). The present study aimed to investigate EH characteristics and their interrelation to neurotologic testing in patients with VM, MD, or VM with concurrent endolymphatic hydrops affects an inner ear, independent control is lost, and the volume and concentration of the inner ear fluid fluctuates with changes in the body's fluid/blood. This fluctuation causes the symptoms of hydrops--pressure or fullness in the ears, tinnitus (ringing in the ears), hearing loss, dizziness and imbalance. The symptoms of endolymphatic hydrops include the feeling of pressure or fullness in the ears, hearing loss, tinnitus, (ringing in the ears), hearing loss, and balance problems. Individuals who have Meniere’s disease have a very severe form of endolymphatic hydrops, but individuals with endolymphatic hydrops do not always progress to Meniere There are two tests that are somewhat specific for Meniere's disease or endolymphatic hydrops.

Endolymphatic hydrops är en mekanisk svullnad som först påverkar de mest känsliga sektionerna i innerörat.
In 2009, the video head impulse test (vHIT) was introduced, which can be the influence of endolymphatic hydrops (EH) on the caloric test and vHIT results.
diagnostic value for delayed endolymphatic hydrops. Methods: Twenty-five patients with delayed endolymphatic hydrops underwent pure tone audiometry, bithermal caloric testing, vestibular-evoked myogenic potential testing and three-dimensional magnetic resonance imaging of the inner ear after bilateral intratympanic injection of gadolinium.

Endolymphatic hydrops is one of several disorders that can affect the inner ear's vestibular system, which is the system responsible for regulating balance. Researchers don't know concretely what causes the disease, but the leading theory is there are abnormal fluctuations in the endolymph fluid, which fills the balance and hearing structures within the inner ear.
Because dehydration tests are relatively specific for endolymphatic hydrops, they may be useful in confirming the presence of disease in patients with atypical presentations. However, because the tests are relatively insensitive, they are not useful to rule out endolymphatic hydrops or as screening tests for the disease. 1997-12-01 · This article reviews the present state of diagnostic testing for endolymphatic hydrops. The use of nonspecific studies, such as basic audiometry and tests for recruitment, and “specific” studies, such as electrocochleography and dehydration testing, are critically reviewed.

BACKGROUND AND PURPOSE: Endolymphatic hydrops has been recognized as the underlying pathophysiology of Menière disease. We used 3T MR imaging to detect and grade endolymphatic hydrops in patients with Menière disease and to correlate MR imaging findings with the clinical severity.

Endolymphatic hydrops is a disorder of the vestibular system, which is part of the inner ear. Endolymphatic hydrops consists of abnormal fluctuations in the endolymph fluid, which fills the hearing and balance structures of the inner ear. These fluctuations cause an increase in pressure in the endolymphatic system of the inner ear.
These fluctuations cause an increase in pressure in the endolymphatic system of the inner ear. Endolymph fluid, which is regulated by the endolymph sac, flows through the inner ear and is critical to hearing. concerning the etiology of endolymphatic hydrops: hy-perproduction of endolymph, slow resorption of en-dolymph, viral infections, ionic imbalance, genetic ab-normalities, dietary factors, allergies, and autoimmune reactions.
