Each duct of the submandibular salivary glands (Wharton's ducts) showed two stones, the largest is approximately 5 mm in size. On the right side, a proximal stone is noted at the hilum of the gland while a distal stone is noted about 1 cm proximal to the terminal ostium. On the left side, a proximal stone is noted at the hilum of the gland while a distal stone is noted at the terminal ostium. Both ducts are mildly dilated reaching 4.5 mm. No definite intraglandular stones or duct dilatation.
The submandibular glands are the commonest site of sialolithiasis. Stone formation occurs at the wharton's duct or intraglandular or both. Sialolithiasis can predispose to sialadenitis.
