'MAGRO, Alessandra Kuhn-Dall et al. Sialolith of submandibular salivary gland: case report. RFO UPF [online]. 2014, vol.19, n.3, pp. 343-347. ISSN 1413-4012.

Objective: this article aims to illustrate a case of sialolithiasis in the submandibular gland. Sialolithiasis is among the most common diseases of salivary glands. It is a slow-growing benign pathology, but of uncertain etiology. Most cases occur in the submandibular gland duct, due to the route of Wharton's duct, which is winding and ascending, with easier deposition of calcium salts and consequent stone formation, besides the greater amount of proteins secreted by the submandibular gland, which makes secretion thicker. Diagnosis is determined by intra- and extraoral assessment, and by the aid of complementary exams such as radiographs, ultrasound, computed tomography (CT), and sialometry. The treatment is closely linked to the size and location of the stone, and whenever possible, the most conservative treatment is chosen. Case Report: female patient, leucoderma, 53 years old, carries a sialolith in the duct of the left submandibular gland. Surgical treatment was performed intraorally into the obliterated duct, keeping the affected gland functioning. The patient was followed for six months after the removal of the sialolith with no postoperative recurrences or complications. Final considerations: according to the case illustrated in this study and the findings of literature review, sialolith is a calcification that occurs in salivary gland ducts, from idiopathic origin, with varying sizes and locations. Therefore, the initial choice of treatment for removing the sialolith should be the conservative one, opting for surgical excision when the first choice of treatment is not feasible, and in extreme cases of excision of the affected gland. Early diagnosis is essential due to painful symptomatology and discomfort.
