Anatomy

The left submandibular gland is a major paired mixed (seromucous) salivary gland situated within the submandibular triangle of the neck. Divided into superficial and deep lobes wrapped around the posterior border of the mylohyoid muscle, its excretory duct (Wharton duct) courses anteromedially to open on the sublingual caruncle beside the frenulum of the tongue.

Clinical notes

Sialolithiasis (salivary calculi) occurs most frequently in the submandibular gland (approx 80% of all salivary stones) due to upward duct course and viscous, alkaline saliva, causing postprandial mealtime swelling and pain.
