Maxillary sinus haematoma.

The maxillary sinus haematoma is an uncommon cause of a maxillary sinus mass. It presents with a variety of symptoms, the most common being epistaxis. Although histologically benign, it may be clinically progressive. Radiological findings can range from a benign appearance to a more aggressive process, including bony erosion. Surgical evacuation is the mainstay of therapy. We describe our experience in managing this condition and review available literature on the subject.
