Transitory Decrease of Hearing after Lumbar Puncture:A personal experience which throws some light on the function of the aqueduct of the cochleae

Abstract

A case is reported of a transitory decrease in hearing after an ordinary lumbar puncture. The symptoms and clinical investigations suggest a cochlear hydrops, presumably originating from a decreased fluid pressure in the subarachnoid space. The aqueduct of the cochlea is thought to be the transmitter of the decreased fluid pressure to the perilymph of the labyrinth.
