The Latin American Botulinum Toxin Symposium (SymTox) came into being in 2005 during the ISPRM Worldwide Congress held in São Paulo, Brazil. The role of SymTox is to provide help and support for medical and health professionals who live and deal with therapeutic methodologies related to botulinum neurotoxin. Our raison d’être: to learn, to share and to update their knowledge and experience alongside professionals who work in this field and/or who are involved in scientific research.
