Necrotizing sialometaplasia (NS) is a rare, benign, self-limiting inflammatory disease of the salivary glands that can clinically and histopathologically mimic malignancy. It most commonly presents as a painful ulcer of the hard palate. The lesion is believed to be the result of ischemia of the salivary gland lobules with subsequent repair and metaplasia. Necrotizing sialometaplasia heals spontaneously and requires no treatment. This report demonstrates a case of NS in a 33-year-old female patient who presented with a bilateral, painful swelling of the hard palate that evolved into an ulcer a few days after surgery with laryngeal mask airway ventilation. Hyperbaric oxygen therapy was attempted to enhance healing.
