[Hypersialorrhea in mental retardation: interest of salivary denervation].

Hypersialorrhea with mental retardation is a handicapping clinical situation with a greater psychoaffective impact and a risk of dyspneic attack by a pharyngeal salivary stasis and a disappointing treatment. We report an observation about a 22 years old child; as for as this child is concerned, the treatment has been a salivary denervation. This method is simple, efficient and without risk.
