Branchio-oto-renal dysplasia and branchio-oto dysplasia: report of eight new cases.

Eight new cases of "ear-pits-deafness syndrome" are reported here; in particular, the audiometric and tomographic findings of the ear and renal echography are discussed. Although it is difficult to give a nosologic definition of the syndrome, these cases can be classified as branchio-oto-renal dysplasia and branchio-oto dysplasia.
