One of two brothers had bilateral and the other had unilateral microtia, meatal atresia, and significant hearing impairment. Reconstruction of the auricles was moderately successful. Temporal bone tomograms on one boy showed absent external canals, abnormal ossicles, and small middle ears. The inner ears were normal. These sibs probably have a recessively inherited syndrome described by Ellwood et al in two siblings and characterized by microtia, meatal atresia, and hearing loss.
