Fibrous hyperplasia involving the orifice of Stensen's duct

This study aimed to describe the clinical features and surgical management of fibrous hyperplasia involving the orifice of Stensen's duct. The clinical data of three patients (one male and two females) were collected and analyzed to characterize this lesion. The lesions surrounding the orifice of Stensen's duct were painless and without obvious causes. The patients' clinical features included sensation of a foreign body and an awkward bite during mastication. All patients received surgical management to resect the polyp and reconstruct the orifice of Stensen's duct. The ducts were preserved intact and parotid glands functioned normally after 12-18 months follow-up. In conclusion, the key point for surgical management of fibrous hyperplasia involving Stensen's duct is to keep the duct intact and unobstructed in consideration of its particular location.
