Blood Labyrinth Barrier Waste Clearance as Assessed by GBCAs on MRI: A Scoping Review. [PDF]

open access: yesLaryngoscope Investig Otolaryngol
ABSTRACT Objective The discovery of the glymphatic system in the brain and eye has raised the hypothesis of a similar system in the inner ear. Dysfunctional lymph fluid dynamics may contribute to inner ear conditions such as Meniere's Disease (MD) and endolymphatic hydrops (EH).
