Giant sialoliths of Wharton duct: Report of two rare cases and review of literature

Hossein Shahoon, Sareh Farhadi, Roya Hamedi


Sialolithiasis is a common disease of the major salivary glands, characterized by the obstruction of a salivary gland or its excretory duct due to the formation of calcareous concretions. Sialoliths usually measure from 1 mm to <10 mm. They rarely measure more than 15 mm, and infrequently giant salivary gland calculi >15 mm have been reported in the literature. The submandibular gland and its duct appear to be the most susceptible sites for this disease. In this article, we report two unique cases, including a giant bilateral case, measuring 50 mm in length and 5 mm in width on the right side and one, 30 mm in length, and 5 mm in width on the left side; and another case, measuring 83 mm in length. The diagnostic and therapeutic approaches consisted of transocclusal radiography

with the conservative transoral surgical technique in both cases. The follow-up showed the normal function of the relevant salivary glands. To the best of our knowledge and belief, similar cases have

not been reported in the literature.
