introduction Recurrent inflammatory diseases of the major salivary glands that occur in childhood and adolescence, for the most part, do not have a defined etiology. Usually, when there is simultaneous involvement of two or more glands, etiopathogenic hypotheses end up being related to autoimmune or genetic factors. 1 However, when repeated inflammation affects only one of the glands, obstructive factors such as stenosis, malformation, and ductal obstruction by calculus and/or debris are a more likely diagnostic hypotheses. 2 Given the difficulty of the etiologic diagnosis, despite the different methods available, the treatment ends up being in large part directed to symptomatic relief. 1 Sialendoscopy (SE) is a relatively new method for diagnostic and therapeutic approach to salivary gland disorders in children, initially proposed in 1997. 3 Various infections of major salivary glands, both in adults and children have been diagnosed and treated by SE. 2 Using an endoscope inserted through the papilla of the affected gland, a direct view of the ductal system is obtained. Although the main objective of SE is to evaluate the anatomic integrity of the salivary ducts, it is possible to act therapeutically in certain cases during the examination procedure preserving the gland and restoring its function. 1,2 SE is a procedure considered minimally invasive, safe, and shows low complication rates. It is indicated as an alternative to open surgery. 4 Even though the technique has been proposed years ago, its indication for the treatment of children is recent. The development of more sensitive instruments has enabled the transfer of skills and experience obtained in procedures performed in adults to pediatric patients. Objective: To review studies on sialendoscopy (SE) of the salivary glands in children focusing mainly on the indications, endoscopic findings, and effectiveness of the procedure. Method: The electronic databases searched were Pubmed, Scielo, and Cochrane. The search was conducted by two researchers independently, following inclusion and exclusion criteria. A third author analyzed sources of conflict. In the first stage they were discarded by reading the articles title that had no relation to the purpose of the study and then evaluated the abstracts of each study. In these two initial phases 37 articles were excluded. Articles not excluded by the selection criteria have been retrieved and assessed in full. Seven articles had their data extracted and were compared. Results: The literature search parameters listed allowed the recovery of 44 articles. After applying the exclusion criteria, seven studies were included in this review representing 207 patients undergoing with ages ranging from 1 to 16 years. All studies except one underwent SE under general anesthesia. The juvenile recurrent parotitis was the main clinical diagnosis related with SE procedures (N=152). The number of inflammatory attacks per patient per year was the parameter for indication of SE. The efficacy of the procedure was considered high by...
