Diagnosis and treatment of congenital dilatation of Stensen's duct

Abstract

Objectives/hypothesis: This study aimed to describe the diagnosis and management of congenital dilation of Stensen's duct (CDSD) in seven cases.

Study design: Retrospective study.

Methods: 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).

Results: 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.

Conclusions: CDSD is an uncommon congenital disorder of the parotid gland. Management with parotidectomy is effective.
