Transductal Sialolithotomy as a Minimally Invasive Management of Submandibular Duct Sialolith: A Case Report

Abstract

Aim: Submandibular sialolithiasis is characterized by salivary duct obstruction leading to recurrent pain and swelling. Modern management emphasizes gland preservation through minimally invasive methods such as intraoral removal and sialendoscopy, guided by precise imaging. Individualized treatment not only ensures complete stone clearance but also restores normal salivary function and improves long-term patient outcomes. Case Presentation: A 55-year-old male patient presented with pain and swelling in the right floor of the mouth associated with pus discharge during meals for three days. Extraoral examination revealed diffuse swelling in the right submandibular region. Intraoral examination showed an inflamed Wharton’s duct opening with purulent discharge and a firm swelling measuring approximately 1.2 × 0.7 cm in the floor of the mouth. Radiographic evaluation using mandibular occlusal radiograph and CBCT confirmed a calcified sialolith in the right Wharton’s duct. Under local anesthesia, a transductal intraoral approach was performed and the sialolith was removed in a single piece. postoperative follow-up showed normal salivary flow and satisfactory healing. Conclusion: Transductal sialolithotomy is a simple and effective treatment for submandibular duct stones, providing good clinical outcomes with minimal complications.
