Aims: The aim of the study was to evaluate different irrigation solutions during sialendoscopy to reduce complaints caused by sialodochitis. Methods: The investigators designed and implemented a retrospective study composed of 94 patients with sialodochitis but no sialolithiasis or relevant stenosis of the salivary duct system. Three different irrigations (normal saline, cortisone single-shot, and cortisone) were used. After the sialendoscopy, the patients were asked about the current status of the affected salivary gland, and the quantity and quality of the gland swelling/inflammation over a follow-up period of 11.6 months (6–24 months). Results: At the time of follow-up, 41 patients (43.6%) no longer had any complaints with the salivary gland in question. In 75.5% of the patients, a satisfying result was achieved. In total, only 3 patients needed submandibulectomy in the course of the study due to persistent complaints. The outcome showed no statistical differences between the mean of the 3 groups (p = 0.149). Conclusion: Sialendoscopy with flushing/lavage seems to be a good treatment option for patients with sialodochitis lacking sialolithiasis. The results of this study suggest that the type of irrigation used during sialendoscopy seems to be secondary.
