    PurposeTo assess the susceptibility of salivary stones to bacterial biofilm formation, which may be involved in the development of salivary gland infection, and to investigate a relation between microbiological aspects and patient characteristics.MethodsThis prospective study comprises of 54 patients with sialolithiasis attended in Helsinki University Hospital during 2014-2016. A total of 55 salivary stones were removed, and studied for biofilm formation using fluorescence microscopy and sonication. The isolated organisms were quantified and identified using matrix-assisted laser desorption ionization time-of-flight mass spectrometry.ResultsBiofilm formation was confirmed on the surface of 39 (70.9%) stones. A total of 96 microorganisms were isolated from 45 salivary stones (81.8%). Two or more organisms were isolated in 33 (73.3%) cases. The main isolates were Streptococcus mitis/oralis (n=27; 28.1%), followed by Streptococcusanginosus (n=10; 9.6%), Rothia spp. (n=8; 8.3%), Streptococcusconstellatus (n=7; 7.3%), and Streptococcusgordonii (n=6; 6.2%). In all patients showing pre-operative (12 cases) or peri-operative (three cases) drainage of pus, the presence of biofilm was detected in microscopy (p=0.004). Four patients showed post-operative infection, and in three of them (75.0%), the presence of biofilm was detected. Increased number of pus drainage was found among patients with reflux symptoms or use of proton-pump inhibitors.ConclusionsSalivary stones are susceptible to bacterial biofilm formation, which could be related with the development and severity of the inflammation and the refractory nature of the disease. Sonication of salivary gland stones could be a useful method for finding the etiology of the chronic infection.

    PurposeTo analyse costs related to the diagnosis and treatment of patients with sialolithiasis and sialadenitis managed with sialendoscopy, and to prospectively evaluate the impact of sialendoscopy on health-related quality of life (HRQoL) in a longitudinal follow-up study.MethodsAll patients undergoing sialendoscopy or sialendoscopy-assisted surgery at a tertiary care university hospital between January 2014 and May 2016 were identified from a surgical database, and the direct hospital costs were retrospectively evaluated from 1year before to 1year after the sialendoscopy. The 15D HRQoL questionnaire and a questionnaire exploring the use of health care services during the preceding 3months were mailed to the patients before sialendoscopy as well as at 3 and 12months after the operation.ResultsA total of 260 patients were identified. Mean total hospital costs, costs related to the sialendoscopy, and complications were significantly higher in sialolithiasis patients than in patients with other diagnoses. 74 patients returned the baseline 15D questionnaire, and 51 patients all three 15D questionnaires. At baseline, the dimensions discomfort and symptoms and distress were lower in patients than in age- and gender-standardised general population, but the total 15D score did not differ significantly. The dimension discomfort and symptoms improved significantly at 3 and 12months postoperatively, and the mean total HRQoL score improved in patients with sialolithiasis at 3months postoperatively.ConclusionsThe costs related to sialendoscopy are substantial and the cost-effectiveness of sialendoscopy warrants further studies. However, sialendoscopy seems to reduce patients' discomfort and ailments and to improve HRQoL at least in patients with sialolithiasis.

    The aim of this prospective study was to evaluate the efficacy of sialendoscopy in the management of adult chronic recurrent parotitis without sialolithiasis. In addition, preliminary results of an initial randomized placebo-controlled trial of single-dose intraductal steroid injection given concurrently with sialendoscopy, are presented. Forty-nine adult patients with chronic recurrent parotitis without sialoliths were included in this study. They underwent sialendoscopy and were randomized to receive either a concurrent intraductal injection of isotonic saline solution or 125 mg of hydrocortisone. Symptom severity was evaluated with visual analogue scale (VAS) and by recording symptom frequency and course with a multiple-choice questionnaire completed preoperatively and at 3, 6, and 12 months after the procedure. The mean VAS score was 5.6 preoperatively and dropped to 2.9 at 3 months, 3.0 at 6 months, and 2.7 at 12 months after the procedure. The VAS score and the frequency of symptoms were significantly lower at 3 (p <0.001), 6 (p <0.001) and 12 (p <0.001) months after the procedure when compared with the preoperative scores indicating that sialendoscopy reduces the symptoms of recurrent parotitis. However, complete permanent resolution of symptoms was rare. Single-dose steroid injection concomitant to sialendoscopy provided no additional benefit, but the current study is not sufficiently powered to determine a clinical difference between the steroid and non-steroid groups. Sialendoscopy appears to reduce the symptoms of chronic recurrent parotitis. While total permanent symptom remission is rare, sialendoscopy can be considered a safe and relatively efficacious treatment method for this patient group.
