Saliva control issues in the neurologically challenged. A 30 year experience in team management.

OBJECTIVE: The objective of this paper is to report the experience of a multidisciplinary team (otolaryngologist, speech-language pathologists, pediatric dentist, and social worker) functioning at a pediatric rehabilitation center have had in the management of 1487 neurologically challenged individuals with saliva control issues assessed from 1976 to the end of 2004. METHOD: The role of each team member is outlined. Management decisions have consisted of no treatment, utilization of oral-motor training program, elimination of contributing situational factors, utilization of medication, surgery and Botox injections of the major salivary glands. RESULTS: Oral-motor programs to improve oral-motor function is essential initially if there is patient compliance. Surgery was recommended in the majority of patients. Submandibular duct relocation with simultaneous sublingual gland excision remains the procedure of first choice for persistent significant drooling. Aspiration is much less common than drooling and is more problematic to treat. Simultaneous ligation of the submandibular and parotid ducts (aka 4-duct ligation) is promising. A recent initiative to inject the major salivary glands with Botox is being evaluated. CONCLUSIONS: Team evaluation with consensus decision making has worked well in this patient population with complex medical conditions.

Botulinum toxin A for treatment of sialorrhea in children: an effective, minimally invasive approach.

OBJECTIVES: To report (1) our experience with botulinum toxin A injections into the salivary glands of pediatric patients with sialorrhea, (2) the clinical outcomes of these interventions, and (3) the associated complication rates. DESIGN: Retrospective cohort study. SETTING: Urban pediatric hospital and pediatric rehabilitation center. PATIENTS: Forty-five neurologically impaired children. INTERVENTIONS: Patients received botulinum toxin A intrasalivary injections between January 2004 and May 2008 at the Hospital for Sick Children in Toronto, Ontario, Canada. All patients received sedation or general anesthesia for their botulinum toxin A injections, which were performed using ultrasonographic guidance. MAIN OUTCOME MEASURES: Posttreatment assessments included the duration of effect, patient complications, saliva consistency, caregiver willingness to repeat the treatment, caregiver satisfaction with the treatment, and caregiver overall assessment of the child's posttreatment quality of life. RESULTS: Forty-five subjects received a total of 91 botulinum toxin A treatments. The mean (SD) duration of effect was 4.6 (5.2) months. Duration of effect (log transformed) was significantly negatively associated with saliva quantity (P = .02), and there was a positive association with both increasing age and female sex, although neither reached statistical significance (P = .08 for each). Seven of the 24 documented complications were major, according to the Society of Interventional Radiology Classification System for Complications by Outcome scale. Thirty-six of the caregivers reported that this treatment improved the child's quality of life (80%). CONCLUSION: Ultrasonographically guided botulinum toxin A injections into the salivary glands are safe and efficacious in the management of sialorrhea in children with neurologic disorders.
