Intraoral removal of a giant submandibular sialolith obstructing Wharton's duct: a case report.

Sialolithiasis is one of the most common pathologies of the submandibular gland; sialoliths account for about 80 percent of all salivary duct calculi. This report presents the unusual case of a large asymptomatic sialolith of the submandibular duct, initially diagnosed as a possible tumor. The giant sialolith was removed via an intraoral approach under local anesthesia. The etiology, pathogenesis, and management of such giant sialoliths are discussed.
