Abstract

Our macroscopical findings in the region of the deeper part of the internal auditory meatus in presbyacusis have been proved also on microscopical sections. The apposition of bone substance with advancing age, causing the compression and atrophy of the acoustic nerve fibres and the reduction of the ganglionic cells has been found also microscopically in cases of clinical presbyacusis.
