Congenital conductive hearing loss in the lacrimoauriculodentodigital syndrome.

An inherited middle ear anomaly that was causing hearing impairment in a 12-year-old girl was treated successfully by a stapedotomy combined with a malleovestibulopexy. Cup-shaped ears, abnormal or absent thumbs, and skeletal deformities of the forearms were present in several members of 3 generations of a family. An autosomal dominant pattern of inheritance was recognized. These features are present in a number of previously described syndromes, but they correspond best with the lacrimoauriculodentodigital syndrome.
