Use of Cone-Beam Computed Tomography in Performing Submandibular Sialolithotomy.

Purpose: Sialolithotomy for submandibular gland lithiasis is a common procedure often performed in the office setting, with the patient under local anesthesia. The location, size, and number of the sialoliths can greatly influence the indication owing to the difficulty of the procedure for hilar and proximal calculi. The purpose of the present study was to report our experience regarding the advantages of using preoperative cone-beam computed tomography (CBCT) to evaluate submandibular gland lithiasis in patients undergoing sialolithotomy for calculi located anywhere in the area of Wharton's duct, with special regard to hilar and proximal calculi.
