Sialoendoscopy

Abstract

Small size, good mobility, round or oval, and distal location of a salivary stone in the main duct predict significantly greater probability of endoscopic removal and consequently are positive prognostic factors.

Sialendoscope-assisted transoral removal of hilo-parenchymal sub-mandibular stones: surgical results and subjective scores

“…The stones, which were all clinically and ultrasonographically classified as intra-parenchymal, were successfully retrieved from all but seven patients, in whom the failure was due to the fact that the stone could not be separated from the gland tissue despite the use of dedicated elevators. This good result is in line with our initial experience 1 and what has been reported by other authors 4 6 16 , and demonstrate that the procedure is effective in removing deep submandibular stones. Most of these can be removed without using a sialendoscope but, in 9% of cases, the bright guidance of the sialendoscopic unit facilitated the search for residual parenchymal microliths that had cracked during removal of the main stone or migrated backwards to the peri-hilar region.…”

Symptom Outcomes After Sialendoscopy‐Assisted Salivary Duct Surgery: A Prospective 6‐Year Study

“…Many prior studies have linked smaller stone sizes, either overall or in the minor axis, to better symptomatic outcomes. 15,17,27,29 Stone size was not associated with the symptom resolution category in our study. However, we could only report on stone size for 51 out of 72 (71%) glands with sialolithiasis, as this information was not always included in the operative report.…”

“…We acknowledge that there are several limitations to our study. Many prior studies have linked smaller stone sizes, either overall or in the minor axis, to better symptomatic outcomes 15,17,27,29 . Stone size was not associated with the symptom resolution category in our study.…”

“…To further place our study in the context of prior literature, Table VI summarizes key findings of select large volume or landmark retrospective and prospective clinical studies of SASDS. [14][15][16][17][18][19][20][21][22][23][24] Overall, if a patient-reported resolution of symptoms 1-year after SASDS, that effect was most often durable. The durability of the initial post-SASDS COSS score improvements from 1-year to 6-years is further demonstrated by the lack of statistically significant differences in all but 3 of the 20 questions in the COSS questionnaire between 1-and 6-years post-SASDS.…”

Patient Outcomes After Unsuccessful Endoscopic Sialolith Extraction

“…Calculi size has been one of the most significant reported factors predicting success for sialendoscopic stone extraction 11–17 . In this study, calculi size was divided into three groups: Smaller than 4 mm, between 4 and 8 mm, and larger than 8 mm.…”
