Introduction: Drooling of saliva is the unintentional loss of saliva from the mouth resulting in excess pooling of saliva in the anterior portion of the oral cavity. It is considered normal in infants and usually resolves itself by 15-18 months of age. It is a common problem in pediatric patients with cerebral palsy or other neurological disorders. Drooling interferes with speech, impairs oral hygiene and contributes to oral dermatitis, aspiration pneumonias and fluid electrolyte imbalances. It has a profoundly negative impact on quality of life and contributes to social exclusion, self-esteem problems and significant discomfort, especially amongst school-aged children. In addition, it can present a serious challenge for caregivers. Various approaches to manage this condition have been described in the literature. Submandibular duct relocation allows salivary flow and is the surgical approach undertaken by the authors.
Objectives: The aim of this study is to share our experience with the surgical approach to drooling children and to evaluate clinical outcomes and long-term caregiver satisfaction outcomes.
Methods: The authors conducted a retrospective study with a review of the medical records of 43 children and adolescents who had been submitted to submandibular duct relocation in the Centro Hospitalar Tondela-Viseu, between January 2003 and December 2017. The authors analyzed the clinical history, bibs used per day before and after surgery, and caregivers' satisfaction was assessed by interview using a questionnaire. The results of this procedure, technical considerations and outcomes are presented in this work.
Results: Forty-three patients (15 girls and 28 boys), between the ages of 3 and 18 at time of surgery (mean age of 9), underwent bilateral submandibular duct transposition for drooling. All children have neurological disorders, with cerebral palsy being the predominant diagnosis. The majority were hospitalized for 1-2 days and no surgical complications were observed. The number of bib or clothing changes fell from more than ten in 23 patients (53%) pre-operatively to less than five in 33 patients (77%) post-operatively. 30% of caregivers were satisfied and 53% were very satisfied with the results of surgery.
Conclusions: The results of this study show that submandibular duct relocation is an effective method in the resolution of uncontrolled drooling in children, contributing to the improvement of children's quality of life. The degree of satisfaction with the surgical results is in agreement with the published international studies, proving once again the effectiveness of the surgical technique implemented in our Hospital.
