Venous Obstruction of the Cochlea Blood Flow and Function

Abstract

The functional significance of the inferior cochlear vein (vena aqueductus cochleae) is further investigated. Occlusion of the inferior cochlear vein resulted in a severe drop in cochlear blood flow and cochlear microphonics. After venous occlusion, increase of blood flow produced by epinephrine is correlated with an increase of the microphonic response. Some general relations between cochlear blood flow, function and oxygen-utilization are discussed.
