[Oto-vertebral syndrome].

The oto-vertebral syndrome is supposed to be caused by an early embryonic exogenous damage which at the same time affects the development of the ear and vertebral column and possibly also causes cardiac anomalies. Animal studies showed that the malformation syndrome originates in the 6th-7th week of embryonic development. The extent of the malformations of the ear and the vertebral column varies. Frequently seen are dysplasia of the external ear and dystopia and atresia of the external ear canal as well as vertebral malformations, mostly involving the thoracic region. Only 4 case reports have been published in the literature. The differential diagnosis includes Goldenhar-syndrome, oculo-vertebral syndrome. Thalidomide-syndrome and chromosomal aberrations. Therapy depends on the extent of the malformations. In case of atresia of the ear canal hearing is first of all improved with a hearing aid, operative procedures are to be planned later on. Child development is promoted with acustic stimulation.
