- Objective To determine the 9 month period eff ect of botulinum toxin A (BoNT-A) injection into the salivary gland
in children with neurologic disorders and sialorrhea by qualifi ed parent/caregiver-administered questionnaires.
Method A total of 17 patients (age 7.6±4.24 years) were enrolled in this study. The degree of sialorrhea was
assessed at the baseline, 2 weeks, 1, 2, 4, 6 and 9 months after injection. Th e Drooling Count (DC) was assessed as
an objective measurement. Th e Drooling Frequency and Severity Scale (DFS) and the Teacher Drooling Scale (TDS)
were evaluated as a subjective measurement. BoNT-A (0.5 unit/kg) was injected into each submandibular and
parotid gland under ultrasonography-guidance.
Results DC, DFS and TDS showed signifi cant improvement at 2 weeks, 1, 2, 4, 6, and 9 months follow-up (p<0.05).
Twelve of 17 cases (70.5%) showed more than 50% reduction in DC from the baseline value.
Conclusion Ultrasonography-guided BoNT-A injection into the submandibular and parotid gland was a safe and
eff ective method to treat sialorrhea in children with neurologic disorders.
