Abstract

BACKGROUND AND OBJECTIVES: Organizing hematoma of the maxillary sinus can be developed by organizing procedure of hematoma in the unaerated maxillary sinus. To our knowledge, this is the second article describing organizing hematoma in the maxillary sinus. We experienced 7 cases recently, and aimed to describe clinical features, radiologic characteristics, and pathological findings.
MATERIALS AND METHODS
Seven patients were diagnosed as organizing hematoma pathologically. We reviewed computed tomography (CT) and medical records to find out clinical features of organizing hematoma of the maxillary sinus. Of seven patients, five were male and two were female. Their mean age was 49 years.
RESULTS
All patients had a history of frequent epistaxis without bleeding tendency. They also complained of nasal obstruction, hyposmia, headache, and cheek swelling. Rhinoscopy revealed obliterated nasal cavity due to bulging lateral wall. CT scans showed soft-tissue densities expanding the maxillary sinus with the minimal contrast enhancement. Destruction of the bony wall was observed in two patients. Endoscopic sinus surgery, Caldwell-Luc's operation, and Denker's operation were applied for the treatment singly or in combination, and resulted in successful outcome.
CONCLUSION
Organizing hematoma should be included in the differential diagnosis when patients have frequent epistaxis and expansile lesion in the maxillary sinus.
