Parotid sialolithiasis in Stensen's duct

Abstract

Salivary duct lithiasis is a condition characterized by the obstruction of a salivary gland or its excretory duct due to the formation of calcareous concretions or sialoliths resulting in salivary ectasia and even provoking the subsequent dilation of the salivary gland. Sialolithiasis accounts for 30% of salivary diseases and most commonly involves the submaxillary gland (83 to 94%) and less frequently the parotid (4 to 10%) and sublingual glands (1 to 7%). The present study reports the case of a 45-year-old male patient complaining of bad breath and foul-tasting mouth at meal times and presenting with a salivary calculus in left Stensen's duct. Once the patient was diagnosed, the sialolith was surgically removed using local anesthesia. In this paper we have also updated a series of concepts related to the etiology, diagnosis and treatment of sialolithiasis.
