This protocol covers the clinical management of sialolithiasis of the sublingual gland presenting alongside submandibular gland sialolithiasis where the stone lies within the proximal to hilar duct system — a location that directly shapes the feasibility and selection of intervention.
The calculus is situated in the proximal to hilar duct system of the submandibular gland. Stone location in this segment is a key determinant of which procedures are technically accessible and appropriate for gland-preserving management.
For appropriately sized and adequately accessible stones, a gland-sparing minimally invasive approach may be feasible. Whether an endoscopic or lithotripsy-based technique is indicated depends on criteria that vary by stone characteristics and anatomical accessibility.
The full decision criteria, technique selection, and alternative pathways are available in the complete protocol below.
