Sialolithiasis occurs frequently in the submandibular gland, but rarely in the parotid gland.
The case of a 38-year-old woman with a calculus in the duct of the parotid gland is reported. CT and sialography showed a stone located in the extraglandular duct at the anterior edge of the masseter muscle.
The patient underwent an intraoral operation to remove the stone in the left cheek. Although calculi in the posterior portion of the extraglandular duct are usually removed by external incision, the extraoral approach often causes facial nerve injury, salivary fistula, and facial scars. Therefore, we used an intraoral approach. The postoperative course was uneventful.
