Drooling in children

Although drooling may occur in healthy children under two years of age, it is commonly observed in neurologically impaired children and carries a considerable social stigma. Drooling can be socially embarrassing, and at times may cause serious medical complications. Drooling may result from the hypersecretion of saliva or, more commonly, the impairment of swallowing. Most of the causes of drooling can be diagnosed from a history and physical examination of the patient. Laboratory investigations are usually unnecessary. Treatment should be directed at the underlying cause whenever possible. No active management is necessary for patients who have little functional and psychological impairment from their objectively mild or intermittent drooling. Treatment options for moderate and severe drooling include physiotherapy, behavioural or biofeedback modification, pharmacotherapy and surgery.
