“…The clinical confirmation is generally supported with radiological imaging; nonetheless, this varies immensely across institutions [ 5 , 6 , 7 ]. Ultrasound (US) of the salivary glands is frequently used in the paediatrics population as it can insonate cystically enlarged ducts that represent as several small and round hypoechoic areas, enlarged intraparotid lymph nodes, or microcalcifications [ 8 ]. In acute phasis, hypervascularity can be detected with Doppler mode.…”

Juvenile recurrent parotitis is a rare inflammatory disease of the parotid gland that shares diverse therapeutic management between institutions. Sialendoscopy has been demonstrated as an efficient diagnostics and therapeutic method with minimal complications; however, due to the rarity of the disease and limited data, there is a lack of universal guidelines on its optimal management. Herein, we retrospectively analysed patients with juvenile recurrent parotitis who had the sialendoscopy performed at our tertiary centre. Descriptive data were retrieved along with the number of swelling episodes one year before and after the sialendoscopy intervention. In the last decade, twenty-nine sialendoscopic procedures were performed at our clinics on twenty-one patients diagnosed with juvenile recurrent parotitis. Most of them underwent the procedure under general anaesthesia (86%). In the year before and after the sialendoscopic procedure, the patients had 3.9 ± 2.7 and 0.2 ± 0.4 episodes of swelling per year, respectively. The difference proved to be statistically significant (p < 0.0001). The complete resolution was noted in sixteen patients (76%); however, the procedure was not repeated on the same side of any patient. Solely one patient had a relapse of the disease reported more than twelve months after the sialendoscopy, nonetheless, one of his exacerbation episodes was already reported in the first year after the sialendoscopy. The mean follow-up period of patients was 48.6 months (range, 13–116 months). All things considered, this study emphasises sialendoscopy as an effective minimally invasive diagnostic and therapeutic tool for the management of juvenile recurrent parotitis.

Objectives: The presence of a catheter required for contrast infusion during sialography obscures imaging of the distal duct. Static imaging via cone beam computed tomography and magnetic resonance sialography fails to address changes that occur dynamically to the anatomy of the flexible salivary ductal system. We aim to identify dynamic changes to the parotid gland by introducing a novel approach to analyze the full extent of Stensen’s duct based on dynamic infusion digital sialography. Methods: Retrospective chart review of a single-center consecutive series of 409 parotid sialograms performed between April 2008 and June 2023 permitted selection of a contemporary series including seven normal sialograms and seven sialograms with stricture(s). Dynamic (fluoroscopic) infusion (iopamidol/gadolinium) sialograms were assessed through blinded review by two radiologists employing the institution’s picture archiving and communication (PACS) system (©2023 Koninklijke Philips N.V., Amsterdam, Netherlands). Measurements determined changes, in two dimensions, to the angle of the masseteric bend and duct length while the catheter was in place (repose), during catheter withdrawal (stretch), and during recoil after withdrawal. Differences in median lengths and angles of Stensen’s duct between the three time points were compared using Wilcoxon matched-pairs signed rank and Mann–Whitney tests. Results: Fourteen patients [median age (IQR), 55 years (24.7); 10 women] were evaluated. The median angle of the masseteric bend was 117.7° in repose versus 155.4° during catheter withdrawal ( P < .001, n = 14). The median distance measured from the Stensen’s duct orifice to the first major ductal bifurcation was 81.5 mm (IQR = 12.3) in repose. The median percent increase in length from repose to stretch was 6.3% ( P < .001, n = 14). Conclusions: Dynamic infusion digital sialography with fluoroscopic recording during catheter removal permits assessment of the distal duct unobstructed by the presence of a catheter. The technique also identifies the dynamic nature and varying length and angulation of Stensen’s duct.
