It is unusual however, to find congenital malformations of the inner ears of individuals who had no obvious hearing loss at birth. Minor morphologic alterations found incidentally in postmortem studies may be considered as anatomical variants of no functional significance.²

We wish to describe the anomalies found in six ears of three individuals who had bilateral progressive hearing losses acquired after birth, and to comment on the embryologic and functional significance of these changes.
