Spontaneous Passage of Stensen’s Duct Calculus following Gland Massage: A Case Report

Abstract

Obstructive parotitis usually occurs as a painful, unilateral swelling of the cheek with a decreased salivary flow and pus discharge, when secondarily infected. The known causes for this condition include commonly, sialoliths, strictures, and/or stenosis of the duct. Imaging in patients with obstructive parotitis has multifactorial benefits ranging from diagnosis to localisation thus, enabling preoperative planning. A 43-year-old female patient presented with features suggestive of obstructive parotitis with secondary infection. The diagnosis was confirmed by Ultrasonography (USG) and a Radiovisiograph (RVG) was performed to localise the sialolith. The patient was admitted and treated with supportive therapy in the form of intravenous antibiotics, milking of the gland, and adequate hydration. Sialolithotomy was scheduled following the resolution of the acute phase of infection. Repeat USG and RVGRVGRVG were performed on the day of surgery to confirm the position of the sialolith but the sialolith could not be located. A panoramic radiograph was performed to confirm the absence of the sialolith. The planned procedure was cancelled, and the patient was continued on systemic antibiotic therapy and anti-inflammatory medication for three more days. On follow-up, copious serous saliva could be expressed from the duct. This highlights the importance of repeating preoperative imaging in patients who have received supportive therapy including gland massage.
