Abstract

Juvenile recurrent parotitis is a rare recurrent inflammation of the parotid glands occurring in children. The etiology remains obscure and the treatment is still debated. In the present study, we perform a systematic review of the literature with the purpose of identifying and discussing the treatment options emerged over the last 28 years in order to prevent recurrent episodes of parotitis. We ultimately included 24 studies. The definitions used for juvenile recurrent parotitis varied widely and none of the selected studies referred exactly to the same definition. Only one was a randomized controlled trial and it showed marked benefits with the use of Bear Bile and Huangqi, two traditional Chinese medicines. Two additional study on sialendoscopy included a control group but was not randomized. All the remaining contributions were case series or case reports. The vast majority (n = 19) of the selected studies reported on sialendoscopy. They all documented improvement of the condition following this intervention. An analysis grouping all these studies (corresponding to 336 children) showed that only 25.8% (95% Confidence Interval: 21.5–30.8) of the treated children had further recurrences. However, the only two controlled study on sialendoscopy showed a similar improvement in controls. The remaining four studies were on sialography (n = 2), on oral appliance in the specific group of children with concomitant dental malocclusion (n = 1) on ductal hydrocortisone infusion through catheter inserted in the parotid duct (n = 1). Improvements were documented in all four contributions. This systematic review of the literature did not consent us to draw definite conclusions on the most suitable treatment for juvenile recurrent parotitis. The available evidence is indeed weak and difficult to interpret because of the scarcity of randomized controlled trials, the heterogeneity of the definitions used and the high rate of spontaneous resolution. Future large and well-designed randomized controlled trials that will include children fulfilling a shared definition of the condition are warranted.
