Four-Duct Ligation for the Treatment of Sialorrhea in Children.

IMPORTANCE

The 4-duct ligation procedure has appeal for its surgical simplicity and limited invasiveness in the management of pediatric sialorrhea. However, more information is required to understand the benefits, risks, success rates, and long-term effects of this intervention.

OBJECTIVES

To report the clinical outcomes of the 4-duct ligation procedure in pediatric patients diagnosed as having sialorrhea and the associated complication rates and to characterize patient and caregiver satisfaction in a consecutive series.

DESIGN, SETTING, AND PARTICIPANTS: This investigation was a retrospective cohort study at an academic tertiary pediatric center and pediatric rehabilitation hospital. Patients included 38 children with neurological impairment who underwent a 4-duct salivary gland ligation (parotid and submandibular glands) between January 1, 2004, and July 31, 2012. The dates of the analysis were August 2013 through February 2015.

MAIN OUTCOMES AND MEASURES

Posttreatment assessments included duration of effect, severity and frequency of drooling before and after the procedure, patient complications, caregiver satisfaction, caregiver recommendation of the procedure, and caregiver overall assessment of the child's quality of life. Clinical and outcome measures were collected before the procedure, 1 month after the procedure, 1 year after the procedure, and at the most recent follow-up (range, 3-8 years).

RESULTS

The study cohort comprised 38 participants. Their median age was 11 years (age range, 5-17 years), and 37% (14 of 38) were female. The mean (SD) duration of effect was 52.6 (20.4) months. Patients with previous sialorrhea management were more likely to demonstrate an improvement in their drooling frequency score at 1 year. Thirteen complications were documented in 12 patients. The most common complications were persistent facial swelling and aspiration pneumonia. Eighty percent (28 of 35) of caregivers reported an improvement in their child's drooling at 1 month, while 69% (25 of 36) and 71% (24 of 34) stated that there was an improvement at the 1-year follow-up and the most recent follow-up, respectively.

CONCLUSIONS AND RELEVANCE

The 4-duct ligation procedure offers a simple, effective, and minimally invasive approach to the management of sialorrhea in children.
