Treatment of Submandibular Sialolithiasis When the Stone Is Bimanually Palpable, Posteriorly Located, and Under 4 mm
This protocol applies to patients with submandibular sialolithiasis where the salivary calculus is confirmed bimanually palpable, situated in the posterior region of the submandibular duct, and measures less than 4 mm in diameter. Stone size and location are the primary factors that define the appropriate intervention in this scenario.
Clinical scenario
The calculus is located posteriorly, is bimanually palpable on examination, and falls below the 4 mm size threshold — a combination that directly determines which treatment pathways are applicable and under what anesthetic conditions they should be performed.
Approach overview partial — full protocol below
For this presentation, an endoscopic approach is among the options applicable — as is a surgical route via an intra-oral approach — with anesthesia selection guided by stone position. The complete decision pathway, including sequencing and specific indications for each intervention, is available in the full protocol.

- sialendoscopy is mainly intended for small stones (less than 4 mm diameter) but can remove stones regardless of their position under local or general anesthesia;
- calculi smaller than 4 mm may be removed using a basket probe, while larger stones will require endocanal fragmentation (endoscopic laser) or external fragmentation (extracorporeal lithotripsy);
