Changes in severity and impact of drooling after submandibular gland botulinum neurotoxin A injections in children with neurodevelopmental disabilities.

ABSTRACT: AIMS:To examine changes in objective and subjective drooling severity measures after submandibular botulinum neurotoxin A injection in children with neurodevelopmental disabilities, explore their relationship, and evaluate if clinically relevant responses relate to changes in the impact of drooling. METHOD:This longitudinal, observational cohort study involved 160 children (92 males, 68 females; 3-17y, mean 9y 1mo, SD 3y 6mo) treated between 2000 and 2012 at the Radboud University Medical Center, Nijmegen, the Netherlands. Repeated measures analysis of variance was used to compare the 5-minute Drooling Quotient (DQ5) and Visual Analogue Scale (VAS) for drooling severity pretreatment and posttreatment, and Pearson's rho to assess their association. A parent questionnaire was used to assess drooling impact in responders (defined as ?50% reduction in DQ5 and/or ?2 SD reduction in VAS for drooling severity 8wks postintervention) and non-responders. RESULTS:One hundred and twelve children (70%) were responders. Their mean VAS for drooling severity and DQ5 scores were significantly lower 32 weeks postintervention compared to baseline. At baseline, the VAS for drooling severity-DQ5 relationship was 'weak' (rs =0.15, p=0.060), whereas it was 'fair' at 8 weeks (rs =0.43, p=0.000) and 32 weeks (rs =0.30, p=0.000). For responders, a significant change was found regarding the impact of drooling on daily care and social interactions at 8 weeks after intervention; most of these effects were maintained at 32 weeks. INTERPRETATION:A clinically relevant response based on a combination of objective and subjective measures of drooling severity was accompanied by positive changes regarding the impact of drooling on daily care and social interactions. WHAT THIS PAPER ADDS:Botulinum neurotoxin A injection into the submandibular glands reduced drooling severity in 70% of children with neurodevelopmental disabilities. Objective (5-minute Drooling Quotient) and subjective (Visual Analogue Scale for drooling severity) measures correlated 8 and 32 weeks after treatment. Objective and subjective measures complemented each other when changes in drooling severity were assessed. Reduced drooling severity was accompanied by positive changes with regard to the impact of drooling.

Project description:AimTo compare the effect of bilateral submandibular duct ligation and botulinum neurotoxin A (BoNT-A) on drooling severity and its impact on daily life and care in children and adolescents with moderate-to-severe drooling.MethodThis was a randomized, interventional, controlled trial in which 53 children and adolescents (31 males, 22 females, mean age 11y, range 8-22y, SD 2y 10mo) with cerebral palsy (58.5%) or other non-progressive developmental disorders (41.5%) were randomized to BoNT-A (n=26) or bilateral submandibular duct ligation (n=27). A parent questionnaire on the severity of drooling in specific positions and daily activities and the impact of drooling on daily life and care was filled out at baseline and 8 and 32 weeks posttreatment.ResultsBoth BoNT-A and bilateral submandibular duct ligation had a positive effect on daily care, damage to electronic equipment and/or furniture, social interactions, and self-esteem. However, bilateral submandibular duct ligation had a significant greater and longer-lasting short- (8wks) and medium-term (32wks) effect on daily care, reducing damage to electronic devices, and improving social interactions and satisfaction with life in general.InterpretationThis randomized controlled trial confirms reduced drooling by both BoNT-A and bilateral submandibular duct ligation, but provides new evidence on improved well-being through a reduction in drooling. Even though there is a greater risk of complications and morbidity after bilateral submandibular duct ligation, compared to BoNT-A there was a significantly greater and longer-lasting positive effect on most outcomes. What this paper adds Bilateral botulinum neurotoxin A (BoNT-A) and submandibular duct ligation had a positive effect on the well-being of individuals with moderate-to-severe drooling. Bilateral submandibular duct ligation had a greater effect on the impact of drooling during daily care than BoNT-A. Bilateral submandibular duct ligation reduced damage to electronic devices and improved social interactions and satisfaction with life.
