Pediatric salivary gland obstructive swelling: Sialendoscopic approach

Objective: To assess the efficacy of sialendoscopy as a diagnostic and interventional procedure for salivary ductal pathologies of children. Design: Prospective case series study. Setting: Tertiary care teaching hospitals. Patients: Eight children were investigated under general anesthesia by sialendoscopy for recurring salivary gland swellings between 2003 to 2004 in two university centers. Intervention: Diagnostic sialendoscopy was used for classifying ductal lesions as sialolithiasis or stenosis. Interventional sialendoscopy was used to treat these disorders. Different variables were analyzed: type of device used for sialoliths fragmentation or extraction, total number of procedures, and size and number of sialoliths removed. Results: Five cases parotid and three cases of submandibular gland recurring swellings were included in the present study. Diagnostic sialendoscopy was possible in all cases. Salivary stones were found in six patients and parotid ductal stenosis in the remaining two. Multiple stones were seen in two cases. Interventional sialendoscopy was also possible in all cases, allowing an intraductal retrieval of the stones in three cases. Two cases required laser fragmentation of the stone. No major complications occurred intraoperatively or during follow-up (mean 18 months). Conclusion: Diagnostic sialendoscopy is a new technique allowing a reliable evaluation of salivary ductal disorders in children, with low morbidity. Interventional sialendoscopy allows early treatment of pediatric sialoliths and stenosis in most cases, avoiding classical open surgery.
