Endolymphatic hydrops is diagnosed by the ENT specialist based on the individual's medical history and symptoms. Generally, standard audiometric testing will 

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. 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. 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.

Endolymphatic hydrops refers to a condition of increased hydraulic pressure within the inner ear endolymphatic system. Typically, endolymphatic hydrops causes a reduced vestibular response in the affected ear, although response may be paradoxically increased secondary to an irritative lesion.

The worth of DPOAE to spot minimal inner ear dysfunction which might be due to endolymphatic hydrops and may otherwise go undetected on pure tone testing 

It consists of an excessive build-up of the endolymph fluid, which fills the hearing and balance structures of the inner ear. Endolymph fluid, which is partly regulated by the endolymph sac, flows through the inner ear and is critical to the function of all sensory cells in the inner ear.

Endolymphatic hydrops testing

ENDOLYMPHATIC HYDROPS AND MENIERE'S DISEASE Last Updated 1/2007 Endolymphatic hydrops and Meniere's disease are disorders of the inner ear. Although the cause is unknown, it probably results from an abnormality of the fluids of the inner ear. In most cases, only one ear is involved but both ears may be affected in up to 20% of patients. The

When the diagnosis of hydrops is entertained, an ABR, or MRI/CT scan (imaging studies) is sometimes  The development of a sensitive and specific diagnostic test for endolymphatic hydrops has eluded investigators for over 30 years. The absence of such a test  The worth of DPOAE to spot minimal inner ear dysfunction which might be due to endolymphatic hydrops and may otherwise go undetected on pure tone testing  Recently, a new diagnostic test, the cochlear hydrops analysis masking procedure (CHAMP) was introduced as a test for endolymphatic hydrops. The aim of this  This is a simple and rapid method and several authors have confirmed its efficiency for identifying endolymphatic hydrops.

Endolymphatic hydrops testing

The absence of such a test has hampered basic and clinical research into Meniere's disease and related entities. 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.

may reflect the deterioration of endolymphatic hydrops and vestibular  A case of posttraumatic endolymphatic hydrops that was confirmed by a positive glycerin test is reported.

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.

A long list of disease processes must be excluded prior to making the diagnosis of hydrops or Meniere’s disease. Tests of hearing, balance, and occasionally imaging are often performed. Pure tone and speech audiometry, as well as electrocochleography (ECoG), are routinely performed at the Ear Institute of Texas. MRI evaluation of endolymphatic hydrops was carried out with a T2-FLAIR sequence performed 4h after intravenous gadolinium administration. The laterality and degree of vestibular endolymphatic hydrops and the presence or absence of cochlear endolymphatic hydrops were recorded.

However, the relationship between the endolymphatic hydrops visualized by MRI and audio-vestibular functional tests have not been sufficiently investigated, such as pure tone audiometry (PTA), electrocochleography (EcoG), and vestibular evoked myogenic … Endolymphatic sac immunohistochemistry of aquaporin-2, V2R vasopressin receptor, sodium potassium chloride co-transporter 2 (NKCC2), and transient receptor potential cation channel V4 (TRPV4) Genetic testing of KCNE1, KCNE3, SIK1, SLC8A1, and SLC26A4 gene mutation for the diagnosis of endolymphatic hydrops (Meniere's disease) caused by endolymphatic hydrops and is a relatively frequent, lifelong disorder affecting pa-tients’ quality of life and work performance.
