Treatment of Sialolithiasis of Sublingual Gland in Sialolithiasis of the Submandibular Gland with the Stone at the Papilla or Distal/Middle Duct
Clinical Scenario
This protocol addresses sialolithiasis of the sublingual gland occurring in the context of sialolithiasis of the submandibular gland, specifically when the stone is located at the papilla or within the distal or middle segment of the duct.
Stone Location & Accessibility
Due to the excellent accessibility of the duct system in this region, stones from the papilla to the middle duct can be approached regardless of their size or state of impaction — making this anatomic location particularly amenable to minimally invasive management.
Treatment Approach (Partial Overview)
Management may involve endoscopic stone fragmentation, with the applicable modality determined by stone characteristics, patient anatomy, and specific anatomic access — and not all fragmentation techniques are appropriate for this stone location.
The complete structured regimen, including all applicable interventions and their indications, is available via the full protocol.

- Due to the excellent accessibility of the duct system, stones from the papilla to the middle duct system can be extracted independently of their size or state of impaction.
- Mechanical fragmentation or ISWL may be indicated in patients with unfavorable anatomic conditions (e.g., reduced mouth opening or even trismus, small and narrow mandibular arch, deep floor of the mouth, extensive gagging reflex) or in those who decline TDS in order to avoid general anesthesia.
- In some of these cases, mechanical fragmentation with microdrills may be an alternative if the stones have a smooth consistency and are not too large.
- If mechanical fragmentation or ISWL is performed, papillotomy or a retropapillary duct incision may be necessary in order to insert sialendoscopes with larger diameters.
- ESWL is not indicated for stones in this location.
