In August, 1955, we published the first results obtained in the treatment of hydrops and other functional vascular conditions, with a new technique elaborated by us: iontophoresis of the inner ear using intratympanic medicinal injections.1 We had previously carried out iontophoresis, using the medicinal substance in the canal, without obtaining satisfactory results; this work was done in collaboration with Dr. Alberto Martinez Visca, who suggested the method to us.2 To this idea of Dr. Martinez Visca we added the intratympanic technique of medicinal injection which by facilitating ionic molecular continuity favors labyrinthine iontophoresis and has given us our first therapeutic successes.
During the nine months that we have studied and applied this new method, we have done 69 iontophoreses in 38 patients with syndromes of organic and functional vascular processes.
For the time being, our experience is based on the use of a powerful vasodilator of the arteries
