Treatment of Sialolithiasis of the Sublingual Gland in Sialolithiasis of the Submandibular Gland with Posthilar to Intraparenchymal Stone

Clinical Scenario

This protocol applies to sialolithiasis of the submandibular gland where the calculus is situated in a posthilar to intraparenchymal location — a less common presentation, accounting for approximately 10% of all submandibular gland stones.

Specific Situation

Posthilar to intraparenchymal stones represent a distinct anatomical challenge within submandibular gland sialolithiasis. The depth of the stone within the gland parenchyma directly influences which interventional options remain feasible.

Treatment Approach (Partial Overview)

When a stone can be visualised endoscopically, an endoscopic interventional approach may be considered as an initial step — though applicability depends on individual stone characteristics. The complete protocol details the conditions and sequence that determine eligibility.

Posthilar to Intraparenchymal Stones
Only approximately 10% of all stones are in an intraparenchymal location.
If the calculi can be visualized during endoscopy, an attempt may also be made to extract small, mobile stones (<3–5 mm) using intSE, including mechanical fragmentation or ISWL, which is more effective than mechanical fragmentation with intSE.
