Accessory Parotid Gland Tumor and Tumor Arising from Stensen's Duct

We treated two cases of tumors arising from accessory parotid gland and Stensen's duct. The first case was a 30-year-old female with a 10-year history of right cheek tumor. Sialo-CT findings suggested that the tumor detached from the parotid gland and enhancement around the tumor was not remarkable. Fine needle aspiration cytology demonstrated normal salivary gland cells. Therefore, this case was diagnosed as accessory parotid gland tumor and extirpation surgery was performed. The other case was an 86-year-old female with a 4 year history of right cheek tumor. Sialography demonstrated obstruction of Stensen's duct. Based on the surgical specimen, this case was diagnosed as tumor arising from Stensen's duct. We discuss the management of the facial nerve during resection of these tumors.
