The Rationale: Sialoliths are calcified organic matter that form within the secretory system of the salivary glands. They rarely measure more than 1.5 cm. Giant sialoliths are rare and defined as a size of 3.5 cm or larger. Patient concerns: Patient complained of the pain and swelling in the right submandibular area for two years with increase in size during meals. Diagnosis: Based on the clinical and radiological investigations. Treatment: Sialolith measuring 39 mm and weighing 7.02 g, was removed in a minimally invasive manner through transoral sialolithotomy using diode 810 µm LASER unit under local anaesthesia. Outcomes: Patient was relieved of the preoperative symptoms and was on follow-up for one year. Take-Away Lessons: Various newer treatment modalities are effective alternatives to conventional surgical treatment of sialoliths. However, transoral sialolithotomy remains the mainstay of management.
