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

Sialolithiasis is a common disorder affecting an estimated 12 in 1000 people each year and it accounts for more than fifty percent of the salivary gland diseases [1]. Although it can be found in children, it more commonly affects adults in their third to sixth decades [2]. There is a male predominance in sialoliths with some authors quoting that over 80% of the salivary calculi occur in the submandibular gland and less than 20% occurs in the parotid gland [3]. The sublingual and minor salivary glands are rarely affected. The great majority of the stones in the submandibular gland are located in the Wharton’s duct, with a ratio of 7:3 compared to intraglandular stones [4].
