Case report of giant sialolith (megalith) of the Wharton’s duct

Abstract

Sialolithiasis is the most common disease of salivary glands. Its estimated frequency is 1.2% in the adult population. Sialoliths most commonly occur in the submandibular glands. The sublingual gland and minor salivary glands are rarely affected. The sialolith usually measures from 1 to <10 mm. Giant sialoliths are classified as those exceeding 15 mm in any one dimension. In literature, large sialoliths or megalith (>15 mm) of Wharton’s duct have rarely been reported. This case report describes a patient presenting with an unusually large sialolith (megalith) of Wharton’s duct, which was 37 mm × 16 mm in the size, the subsequent patient management, the etiology, diagnosis, and its treatment.
