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. 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 characte … 2021-03-04 · disease, and particular, hydrops (swelling of the inner ear). ECOG may also be abnormal in perilymph The common feature connecting these illnesses is an imbalance in pressure between the endolymphatic and perilymphatic compartment of the inner ear. ECOG can also be used to show that the cochlea is normal, in persons who are deaf.

Request PDF | Distortion-Product Otoacoustic Emissions and Glycerol Testing in Endolymphatic Hydrops | Aural fullness is a frequent symptom of endolymphatic hydrops. Its evaluation may provide Typically, endolymphatic hydrops causes a reduced vestibular response in the affected ear, although response may be paradoxically increased secondary to an irritative lesion.

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.

ECOG can also be used to show that the cochlea is normal, in persons who are deaf. Endolymphatic hydrops is diagnosed by the ENT specialist based on the individual’s medical history and symptoms. Generally, standard audiometric testing will diagnose the hearing loss of individuals with aural problems. 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.

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.

Endolymphatic hydrops testing

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 potential (VEMP).

Endolymphatic hydrops is a disorder of the inner ear and can affect the endolymphatic fluid of the cochlea, the vestibular apparatus, or both. Although its underlying cause and natural history are unknown, it is believed to result from abnormalities in the quantity, composition, and/or pressure of the endolymph (the fluid within the endolymphatic sac, a compartment of the inner ear). Endolymphatic hydrops may occur as a result of trauma such as a blow to the head, infection, degeneration of the inner ear, allergies, dehydration and loss of electrolytes or in extremely rare circumstances a benign tumor such as an endolymphatic sac tumor.
