Two Cases of Organized Hematoma of Maxillary Sinus with Bone Erosion

ABSTRACT

An organized hematoma in the maxillary sinus can be formed by organizing procedure of hematoma in the unaerated maxillary sinus. It is a rare disorder of unknown etiology. Clinical symptoms, signs, and radiologic appearance of the hematoma mimick tumors at the initial diagnosis. An expansile organized hematoma in the maxillary sinus may induce erosion or destruction of the maxillary bony wall. Therefore, it may be difficult to distinguish such lesion from malignant tumors. We report two cases of an organized hematoma in the maxillary sinus presenting with erosion of the maxillary sinus wall with a brief review of the literature.
