When sialolithiasis of the sublingual gland occurs in the setting of sialolithiasis of the submandibular gland with a stone in a posthilar to intraparenchymal location, a specific management approach applies. This deep-seated stone position represents a clinically distinct presentation requiring targeted intervention.
Sialolithiasis of the submandibular gland with the stone situated in a posthilar to intraparenchymal location. Only approximately 10% of all stones are found in an intraparenchymal location — making this a less common but clinically significant presentation where conservative stone-removal approaches are typically not feasible.
Management in this setting centres on a surgical approach directed at the gland itself, considered in therapy-resistant cases and when symptoms persist. For patients who are not suitable candidates for surgery, an alternative injection-based approach may be considered. The full structured protocol — including specific indications, sequencing, and all options — is available via the link below.
