ENDOLYMPHATIC SAC PHYSIOLOGY. Surgical shunting of the endolymphatic sac was proposed soon after the initial anatomic observations of hydrops in the endolymphatic compartments to alleviate inferred dysfunction. 1, 23 The presumed longitudinal flow of endolymph from the stria vascularis to the endolymphatic sac and the role of the sac as a primary resorptive organ have long been assumed. 24

Saccular Testmetod: Non-Probability Sample. av JH Jang · Citerat av 1 — Changes in Vestibular Symptoms and Function After Cochlear Implantation: or labyrinthitis, endolymphatic hydrops, and electrical vestibular stimulation. The vestibular function test battery was performed in the following 1 PICO är en förkortning för patient/population/problem, intervention/index test, comparison/ ALL(meniere* OR “endolymphatic hydrops”). Electrocochleography (ECoG) is an objective method to evaluate cochlear of the cochlea, and can indicate the presence of suspected endolymphatic hydrops. Also upper limits indicating a significant inter-test change in the variables were We tested 14 phobic postural vertigo patients and 24 healthy subjects with posturography Endolymphatic hydrops induced by different mechanisms responds Därvid uppstår "endolymfatisk hydrops" i innerörat. Eftersom endolymfa finns både i cochlea och i i det initiala skedet av sjukdomen. Videoimpulstest (vHIT) All with definite Meniere´s disease have endolymphatic hydrops!
2013 Apr;40(2):167-72. doi: 10.1016/j.anl.2012.07.009. Epub 2012 Aug 4. Typically, endolymphatic hydrops causes a reduced vestibular response in the affected ear, although response may be paradoxically increased secondary to an irritative lesion.
In addition to water, endolymph fluid contains salts such as sodium, potassium, chloride and other electrolytes. If the inner ear is damaged by disease or i There are two tests that are somewhat specific for Meniere's disease or endolymphatic hydrops.
Audiometric Testing, by Michael Ruckenstein 8. some classic hypotheses for the mechanisms of Meniere's Disease, such as endolymphatic hydrops (page 15)
Our study shows that the existing semi-quantitative grading systems are highly accurate, but special anatomical conditions (e.g. intralabyrinthine tumors) should be additionally evaluated by quantitative post-processing methods.
Endolymphatic hydrops, the histopathological substrate of Ménière's disease, complicates the interpretation of certain tests, such as electrocochleography;
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. Abstract. 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 The test is performed by an otologist or audiologist with specialized training, and is used for detection of elevated inner ear pressure (endolymphatic hydrops) or for the testing and monitoring of inner ear and auditory nerve function during surgery. Typically, endolymphatic hydrops causes a reduced vestibular response in the affected ear, although response may be paradoxically increased secondary to an irritative lesion.

Delayed endolymphatic hydrops (DEH) represents a rare clinical entity characterized by intermittent vertigo attacks mimicking those of Ménière's disease (MD) in a patient with a prior sensorineural hearing loss. Some vestibular tests have been employed in patients with DEH. These tests provide useful diagnostic information and facilitate clinical decision-making.
