Ganglion Cell Counts in the Cochleae of Patients with Normal Audiograms

Abstract

Spiral ganglion cells were counted in the right cochleae of 16 patients with normal audiograms and without a history of hearing deficit or other auditory symptoms. Total counts ranged from 29 802 to 38 352, with a mean of 33 623. There was no relationship between total counts and patient age or between total counts and length of either the cochlea or the spiral ganglion.
