RECURRENT OBSTRUCTIVE PAROTITIS SECONDARY TO CONGENETAL KINK OF STENSEN’S DUCT

Abstract

Parotitis is an inflammation of one or both parotid glands located on either side of the face. The parotid gland is the salivary gland most commonly affected by inflammation. Causes of parotitis include infections, blockage, autoimmune and diseases of uncertain etiology.

Chronic parotitis is an insiduous inflammatory disorder involving the parotid gland. It is characterized by a recurrent and painful swelling of the affected salivary gland. Pain may be worse while eating due to the stress placed on the inflammed gland to secrete saliva. Blockage of the main parotid duct, or one of its branches, is often a primary cause of recurrent parotitis. The blockage may be from a salivary stone, a mucous plug, or, more rarely, by a tumor, usually benign. A very rare cause of blockage of pancreatic duct is kink in the duct may be due to congenital course of duct or due to hypertrophy of masseter muscle causing its kink. Sialography is most reliable technique to diagnose the cause and site of blockage.

We present a case of 45-year-old female patient presented with recurrent pain and swelling of right parotid region. His X-Ray lateral side of face was unremarkable. His sialography revealed a kink in its course with dilatation of Stensen’s duct proximal to kink along with beaded appearance of duct.

Key words: Parotitis , Stensen’s duct, sialography, blockage , kink.
