Sialolithiasis in a Remnant Wharton’s Duct: a Case Study and Discussion

A common indication for removal of the submandibular gland is recurrent infection due to the presence of a stone (sialolith) in Wharton’s Duct. We present a case of infection due to sialolithiasis in a remnant of Wharton’s duct, 11 years after removal of the submandibular gland. A literature review of this unusual condition and various management options in treating submandibular sialolithiasis has been performed and discussed. Stones may be present and become symptomatic in remnant Wharton’s ducts, either remnant from original surgery or via de novo formation. We suggest that patients undergoing submandibular gland excision for sialolithiasis should be made aware of this.
