Diagnosis and treatment of congenital dilatation of Stensen's duct

Abstract

This study aimed to describe the diagnosis and management of congenital dilation of Stensen's duct (CDSD) in seven cases. Retrospective study. We collected data including medical records, radiology, and histopathology findings and follow-up for seven patients (four males) with CDSD. The mean age was 23.9 years (range, 2-72 years). The clinical features of CDSD were the primary presentation of painless swelling in the cheek without an obvious cause that was unilateral or bilateral and occurred at any age, and a swelling along Stensen's duct. In patients without a history of inflammation, aggressive massage of the swelling could produce abundant intraoral salivary flow. Parotid sialography demonstrated a dilated Stensen's duct with a smooth margin but no obvious obstruction. All seven patients underwent superficial parotidectomy including the intact Stensen's duct. No patient showed recurrent swelling after a follow-up of 6 to 65 months. CDSD is an uncommon congenital disorder of the parotid gland. Management with parotidectomy is effective.
