Enormous Asymptomatic Intraoral Sialolithiasis: A Case Report.

Abstract

Sialolithiasis is one of the most common diseases of salivary glands. More than 80% of the sialoliths occur in the submandibular gland. While most of the calculi are less than 10 mm in size, 7.6% are larger than 15 mm and are classified as giant sialoliths. We demonstrate a rare case of asymptomatic giant sialolith in the left Wharton's duct with a total atrophy of the left submandibular salivary gland. A 48-year-old female patient presented with lumping sensation for 1 month. A left mouth floor mass was found accidentally during examination and was later revealed to be a painless sialolithiasis. Image study revealed a giant sialolith in the left Wharton's duct with duct dilatation and left submandibular gland total atrophy. She underwent transoral sialolithotomy with removal of a huge stone, measuring 3.5 × 1.4 cm in size. Sialolithiasis usually presents with typical symptoms of the involved salivary gland, and the size of calculi is usually less than 20 mm. This is a rare case report of an asymptomatic giant sialolith in the Wharton's duct, causing left submandibular salivary gland total atrophy, and its diagnosis and management.
