AZENHA, Marcelo Rodrigues et al. Extensive sialolit located at submandible gland ducts: diagnosis and surgical treatment. Odontol. Clín.-Cient. (Online) [online]. 2013, vol.12, n.1, pp. 87-89. ISSN 1677-3888.

Sialolithiasis is characterized by the formation of calculi (sialoliths) inside salivary glands duct system resulting in salivary ectasia and subsequent salivary gland dilation. Calculi are composed of organic and inorganic substances with its pathogenesis remaining unknown. Two main hypotheses are proposed: one consists of accumulation of pre existence intracellular micro calculi that accumulates in the course of time. The second theory suggests that aliments and bacteria presents inside the oral cavity migrate into the salivary ducts cause its obstruction. After clinical and/or radiographic sialolithiasis diagnosis different treatment modalities may be performed to treat this condition including surgical excision followed by ductal reconstruction or interventional sialendoscopy. The aim of this presentation is to demonstrate surgical excision of a large submandibular duct calculus in a patient complaining of constant pain at right mandible region, mouth floor elevation, diminish of salivary secretion, and slight tongue deviation. Surgical excision was conduct with totally calculi extirpation and submandibular duct reconstruction. Normal submandibular salivary flow was observed after 18 months of follow-up with no recurrence episodies.
