Abstract

Sialolithiasis is the formation of calcareous concretions within ductal system of a major or minor salivary gland. They are formed by deposition of calcium salts around a central nidus which may consist of desquamated epithelial cells, bacteria, foreign bodies, or products of bacterial decomposition. An 11-year-old boy complained of pain during meals and intermittent mild swelling in the right submandibular region. Although it was not detected in true occlusal radiograph, panoramic radiograph showed a round radiopaque mass 3mm in diameter. Computed tomography(CT) was taken for locating the stone and 3-dimensional reconstruction was performed. Under general anesthesia, sialoadenectomy was done through extraoral approach. Diagnosis of submandibular sialolithiasis using high-resolution CT with reconstructions was helpful for surgical decisions, namely radical removal of the submandibular gland and its duct.
