Osteogenesis imperfecta is a rare hereditary illness of collagen that in its lately form is characterized by a tendency to spontaneous fractures, blue sclerae and articolary hypermobility. A hearing loss, usually a conductive one, is also often present. The Authors argue about the etiology, the physiopathology, the clinical picture and especially about deafness presenting some of the cases they had the opportunity to observe. Their causitry regards twelve children aged one to ten. They have been subjected to several exams among which on ORL visit, the tonal audiometry, the tympanometry, the vestibular examen, and the X-ray of the temporal bones and of the mastoids. Where is was necessary the audiological examination has been done using REA. Seven patients turned out to be deaf; five of them had a conductive hearing loss, two of them a sensoryneural hearing loss, and one a combined hearing loss.
