Sialorrhoea (drooling or excessive salivation) is defined as saliva extending beyond the margin of the lip. This is physiological in infants but usually stops by 15 to 18 months of age. It is common in children with cerebral palsy and other neurological impairment. Treatment of sialorrhoea is challenging and frequently requires a multi-disciplinary approach. Conservative measures like behaviour modification and oromotor exercises could be trialled in mild to moderate degrees of drooling. Parasympatholysis with Botulinum toxin injection into the salivary glands could be attempted although the dosage remains controversial. Various surgical procedures have been described and should be considered in severe cases of sialorrhoea.
