Endoscopic Surgical Treatment of Maxillary Sinus Organized Hematoma

Objective: The purpose of this study was to analyze the clinical characteristics and treatment outcomes of patients who underwent endoscopic surgery for a maxillary sinus organized hematoma during a 15-year period in our hospital. Methods: The authors analyzed 25 patients who underwent endoscopic surgery for a maxillary sinus organized hematoma from January 2004 to December 2019. Results: Twenty-five patients with a maxillary sinus organized hematoma underwent endoscopic surgical treatment and complete removal of the maxillary sinus organized hematoma was achieved in all cases. The main symptoms were nasal bleeding in 14 patients, followed by a nasal obstruction in nine, and facial swelling in 2. Of the 25 patients, 13 underwent endoscopic medial maxillectomy and 12 underwent endoscopic sinus surgery. There were no major surgical complications or recurrences. Conclusion: The authors demonstrated that endoscopic surgery is a safe and reliable treatment method for a maxillary sinus organized hematoma.
