The photograph below shows a prominent submandibular gland
The submandibular gland has been dissected and retracted inferiorly.  A large stone is visible through the thin wall of the distended submandibular duct.  The anterior portion of the duct is still normal in size, as it courses to the floor of the mouth above the lingual nerve.  The marginal mandibular branch of the facial nerve is behind the upper margin of the incision and is not visible. The hypoglossal nerve is hidden behind the submandibular gland and the digastric muscle.  The angle of the mandible is marked with a blue line.
