Mario E. Zernotti is professor of ENT at Catholic University of Córdoba and National University of Villa Maria, and also professor of Clinics of Hearing at National University of Córdoba. He has more than 30 years of experience in the field of ear surgery in Sanatorium Allende. He was the pioneer in electro acoustic stimulation (EAS) and hearing preservation in all America, doing the first cases of EAS cochlear implants in the continent.  Besides, his team was the first to did Active Middle Ear Implants and bone conductive prosthesis in the region. This group is working specially in atresia/microtia patients, very common malformation in South-America, and northwest of Argentina, doing a comprehensive approach to the problem.
