[Subcophosis and otosclerosis. Medical and surgical treatment].

The spiral ligament of the stria vascularis is nearly always damaged by otosclerotic foci when the patient is nearly totally deaf because of otosclerosis. Vascular drugs are to be prescribed in such a case, besides the Sodium Fluoride treatment. The Sodium Fluoride is, according to us, the best treatment to arrest the progression of the otosclerotic disease. Sodium fluoride will destroy the proteolytic enzymes damaging the inner ear membranes and the hair of the Corti hair cells.
