What is the most common medical intervention for sialorrhea in children with cerebral palsy?

• A. Therapy to increase swallowing frequency
• B. Labial and lingual strengthening exercises
• C. Botulinum toxin injection
• D. Removal of the salivary glands

Answer: (C)

Saliva management in cerebral palsy is most effectively achieved by lowering saliva production at the source, since drooling often results from impaired oral motor control combined with an inability to swallow and clear saliva efficiently. Injecting botulinum toxin into the major salivary glands reduces the amount of saliva they produce for several months, which directly reduces drooling. This approach is minimally invasive, can be done on an outpatient basis (often with ultrasound guidance), and its effects are reversible, making it a practical first-line medical intervention in many children with CP. Therapy aimed at increasing swallowing frequency or strengthening the lips and tongue can help improve oral motor function, but they don’t address the fundamental excess saliva production and thus are typically adjuncts rather than the primary solution. Removal of the salivary glands is invasive and irreversible, reserved for very refractory cases after other options have failed.
