The Largest Asymptomatic Sialolith: Report of a Rare Case

Sialolithiasis is the most common pathology affecting the salivary glands. The submandibular gland is most commonly affected. Sialoliths typically causes pain and swelling in the affected gland. They usually range in size from 1 to 10 mm, while those larger than 15 mm are considered rare. The exact etiology of sialolith formation remains unknown. We report the case of a 62-year-old patient with submandibular gland sialolith, that was incidentally discovered during imaging performed for dental implant planning. Remarkably, the patient was completely asymptomatic, despite the stone being giant in all three dimensions. Cone-Beam Computed Tomography (CBCT) of the mandible revealed a radiopaque lesion posterior to the mandibular Body, measuring approximately 2.8×1.8×2 cm. The sialolith was successfully removed using a minimally invasive transoral sialolithotomy.
