title: [Studies on the genetics of otosclerosis (author's transl)].
abstract: 101 families with confirmed otosclerosis were investigated, and after correction for age an incidence was found of otosclerosis of 29.5% amongst the parents, 17.9% amongst the siblings and 8.8% amongst offspring. The statistical data for otosclerosis published to date were treated similarly giving together with our own as large a collection as possible. From this the risk of repeat occurrence of otosclerosis could be calculated to 10% in the brothers and 20% in the sisters of otosclerotic patients. The risk rates of occurrence for their children are the same. These data are intended for use in the genetic counseling of this disorder.
