cupulolithiasis

English

Etymology

From cupula +‎ -o- +‎ lithiasis.

Noun

cupulolithiasis (uncountable)

1. A rare ear condition in which otoliths adhere to a semicircular canal cupula, rendering it heavier than the surrounding endolymph. Upon reorientation of the head relative to gravity, the cupula is weighted down by the dense particles, inducing an immediate and maintained excitation of semicircular canal afferent nerves.
