Endolymphatic hydrops (EH) refers to a dilation of the inner ear fluid chambers. This can occur in Meniere’s Disease. The processes that cause Endolymphatic Hydrops including Meniere’s Disease (MD) are not well understood.
Traditionally the symptoms ascribed to EH include a sensation of pressure or fullness in the ear, tinnitus, hearing loss, and dizziness/vertigo. i.e. the same symptoms as Meniere’s Disease. The term EH may be used when there is insufficient features of full MD. I often note patients with EH have some feature Migraine or a past history of Migraine. Sometimes the features of Migraine are subtle e.g., post neck pain or blurred vision, or sensitivity to sound and lights.
Treatments are as set out for MD (see here) and Migraine (see here). This includes eliminating caffeine, reducing salt intake, increasing hydration, and the option for treatment with certain medication. Occasionally steroid medication can help.
