This protocol applies to sialolithiasis of the sublingual gland occurring in the context of sialolithiasis of the parotid gland with the stone situated in a hilar to intraparenchymal location — an anatomically deep subset that affects up to 20% of all parotid calculus cases and shapes the available management options.
Hilar to intraparenchymal stones represent a distinct anatomical category within parotid sialolithiasis. Up to 20% of all stones are found in an intraparenchymal location, a finding that directly influences the feasibility and selection of interventional techniques.
Where calculi can be visualised during endoscopy, minimally invasive endoscopic methods — directed at stone extraction, mobilisation, or fragmentation — may be considered. The complete protocol specifies the precise conditions, methods, and sequence that apply to this anatomical scenario.

Hilar to Intraparenchymal Stones
Up to 20% 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 using endoscopy, mobilization, or fragmentation (see above).
IntSE and ISWL may be applied in favorable anatomic situations.
