###### Abstract  
Introduction: Juvenile recurrent parotitis (JRP) is characterized by intermittent swelling of one or both parotid glands, accompanied by pain and associated with non-obstructive sialectasia. Sialoendoscopy is considered a significant treatment for JRP, being a safe and minimally invasive treatment method with good clinical outcomes. The purpose of this study was to assess the procedure of sialoendoscopy as a treatment modality for JRP and discuss the relevant literature on this topic. Methods: This study retrospectively reviewed clinical records of children diagnosed with JRP who were treated in the Maxillofacial Department of the Tzafon Medical Center, Poriya, Israel, with sialoendoscopy between May 2016 and March 2023. Data on demographics, the site of symptoms, follow-up duration, treatment outcome, and complications were collected for each patient. The inclusion criteria were patients not older than 16 years of age, with at least two episodes of swelling of the parotid gland unilaterally or bilaterally during a time period of 6 months. The exclusion criteria were patients older than 16 years of age, and patients who were diagnosed with sialolithiasis or Sjogren's syndrome. Results: The study included 17 children, of whom 12 (70%) were boys and 5 (30%) were girls. The mean age of the children at the time of the procedure was 6.7 years and ranged from 3 to 16. The affected parotid gland was the left in 7 children (41%), right in 9 children (53%), and bilateral in 1 child (6%). The average follow-up time was 45.17 months and ranged from 5 to 81 months. A total of 15 children (88%) were deemed to have a successful treatment result regarding the frequency of episodes after therapy and subjective improvement. Full resolution was seen in 10 children (59%). The sialoendoscopy findings were avascularity in the walls of the parotid duct, structures, and mucous plugs. Pathological findings in sialoendoscopy were found in 11 out of 12 asymptomatic contralateral glands (\(p\)-value > 0.001). Conclusions: Sialoendoscopy under general anesthesia is a worthwhile and practicable treatment method for treating JRP. Satisfactory results were seen in the vast majority of patients. It is recommended to perform bilateral sialoendoscopy also in cases of a unilateral symptomatic gland. This treatment method is effective, safe, and potentially repeatable.

increases vulnerability to secondary infection. Yet JRP is still considered an inflammatory response rather than a result of recurrent bacterial infection [7]. The common time of onset is from 3 to 6 years of age, typically self-limiting by puberty, and more common amongst males [8; 9; 10]. Symptoms of JRP include intermittent swelling of one or both parotid glands accompanied by pain, local erythema, masticatory difficulty, and local or systemic fever. An episode of JRP will most likely last a few days, will seldom persist for weeks, and intervals between episodes may be as long as a few years [9]. A preliminary diagnosis is usually made based on clinical findings and elimination of other diseases such as dental or viral infections, or Sjogren's disease [2]. Diagnostic criteria for JRP were suggested in a meta-analysis by [PERSON] et al. [11]. According to this meta-analysis, the inclusion criteria for JRP are recurrent unilateral or bilateral swelling under the age of 16 years, with at least two episodes over 6 months. Exclusion criteria are obstructive lesions in the parotid gland, dental malocclusion, Sjogren's syndrome, and congenital IgA immunodeficiency. In general, the diagnosis of JRP is made mostly clinically, based on physical examination and personal history. Laboratory investigation is also included, as it was shown that the activity of serum amylase may be used in assessment of the salivary gland function, or even as a diagnostic marker [12].
