The Origin of Perilymph Albumin

Abstract

Results are presented of analyses of serum, CSF, perilymph and endolymph electrophoretic mobilities in 24 cadaver ears. On an average, perilymph and CSF albumin had identical mobility whereas the mobility index of serum albumin was clearly slower than the other two. It is concluded that perilymph albumin, as a rule, has its source in the CSF space and is apparently transported through the cochlear or vestibular aqueduct or along the eighth nerve through foramina at the internal acoustic meatus.
