General Secretary YO-IFOS, Pediatric ENT Department, Robert Debré Hospital, Paris, France Professor Natacha Teissier has been practicing pediatric ENT in Robert Debré Hospital in Paris since 2004. She is specially trained in all forms of paediatric otolaryngology and rhinology but is particularly interested in otological surgery and facial clefts. She is currently involved in coordinating the multi-specialty follow-up of children with congenital CMV infection, and specially the ENT aspects. Since 2008, she has been doing research on the neurosensory sequelae in congenital CMV infection. Based on data acquired both on human specimens and on a murine model, she has contributed to understanding the pathophysiological mechanisms of hearing loss and vestibular disorders due to this viral infection. She is now also working on assessing olfactory deficits in congenitally infected children.
