Treatment of Sialolithiasis of the Sublingual Gland in Sialolithiasis of the Submandibular Gland — Stone at the Papilla or Distal/Middle Duct

This protocol applies to sialolithiasis of the sublingual gland occurring in the context of sialolithiasis of the submandibular gland, specifically when the stone is situated at the papilla or within the distal or middle duct.

Due to the excellent accessibility of the duct system in this region, stones located from the papilla to the middle duct can be addressed regardless of their size or degree of impaction — a factor that directly shapes the choice of intervention.

Management in this scenario centres on a surgical approach directed at the duct. Transoral duct surgery is typically the primary option. Depending on stone characteristics, an endoscopic extraction technique may also be considered as an alternative. The full protocol specifies which approach applies under what conditions and how each is performed.
