Abstract
There is an increased incidence of submandibular gland duct developing sialoliths. Among them the sialoliths attaining a size of more than 1.5 cms are rare. Here we present a case with an abnormally sized sialolith in Wharton's duct and a review of the literature about the abnormally sized sialoliths and various anatomical and physiological considerations of the duct which contribute to the higher incidence of sialolith in the duct.
Highlights
Sialolith is one of the most common diseases of salivary glands
It is estimated to have a frequency of 0.15% in the adult population with slight male predilection [1, 2]
Most sialoliths (80–90%) develop in the submandibular gland: 5– 10% develop in the parotid gland and the remainder in the sublingual and minor salivary glands [3,4,5]
Summary
Sialolith is one of the most common diseases of salivary glands. Most sialoliths (80–90%) develop in the submandibular gland: 5– 10% develop in the parotid gland and the remainder in the sublingual and minor salivary glands [3,4,5]. Sialoliths are always found in the distal portion of the duct or at the hilum of the submandibular gland with a few in parenchyma [6]. Sialolith measures from 1 mm to less than 1 cm. They rarely measure more than 1.5 cm. Giant sialoliths are rare [7]. Literature search found 30 cases, each measuring more than 1.5 cm or more have been published (Table 1). The aim of this paper is to present a case of an unusually sized sialolith and review of the literature on large sialoliths (1.5 cm or larger)
