After some brief considerations about the etiopatogenesis of the hereditary deafness, and the modern classification of its different nosologic pictures, the AA. pass on to consider four cases of female sex, two sisters and two cousins of mother side, with hereditary familiary deafness, apparently boun to the sex. All the four cases are characterized by the identity of the audiometrie findings, after the « Law of the symmetry of the hereditary deafness ».
The AA. discuss at least the modality of the hereditary transmission and the anatomopatologic picture of the morbide form.
