Submandibular Gland Excision in Pediatric Patients.

INTRODUCTION

Children who require submandibular gland excision for ptyalism often have multiple associated comorbidities, including neurodevelopmental disorders and respiratory risk factors. The purpose of this study is to utilize a large multicenter database to elucidate the perioperative profile of submandibular gland excision in children, with particular focus on children who require submandibular gland excision for ptyalism.

METHODS

The American College of Surgeons National Surgical Quality Improvement Program Pediatric dataset was queried for submandibular gland excision performed from 2012 through 2018. Indications were subclassified based on International Classification of Disease (ICD)-9 and ICD-10 codes. Complications, readmissions, and reoperations were analyzed with appropriate statistics.

RESULTS

During the study interval, 304 pediatric patients underwent submandibular gland excision, which was mostly performed for ptyalism (56.9%), followed by inflammatory conditions (20.7%). Patients requiring submandibular gland excision for ptyalism were significantly younger (P < 0.001) and underwent significantly longer procedures (P < 0.001). Ptyalism was associated with significantly higher related adverse events (P = 0.010), related readmission (P = 0.013), and medical complications (P = 0.013), which included a significantly higher risk of pneumonia (P = 0.050). Children with ptyalism had significantly higher rates of overall respiratory comorbidities (P < 0.001), including chronic lung disease (P < 0.001), supplemental oxygen support (P < 0.001), tracheostomy (P < 0.001), and ventilator dependence (P < 0.001). Patients undergoing submandibular gland excision for benign (P all ≥ 0.082) and malignant (P all ≥ 0.565) neoplasms did not have significantly higher rates of any indexed postoperative adverse event.

CONCLUSIONS

Children requiring submandibular gland excision for ptyalism represent a unique cohort than those requiring excision for other indications, with significantly higher burden of preoperative risk factors, intraoperative durations, and postoperative adverse events.
