Description

<p>Objective: An organized hematoma is a benign mass lesion that easily bleeds and frequently occurs in the maxillary sinus. The first-line treatment is usually surgical removal of the hematoma. Preoperative embolization is sometimes performed to avoid intraoperative heavy bleeding. We report the case of an elderly patient with high surgical risk who underwent vascular embolization alone that resulted in a good hemostatic effect and reduction of the mass.</p><p>Case Presentation: An 87-year-old man had repeated severe epistaxis requiring blood transfusion from an organized hematoma of the left maxillary sinus. The left sphenopalatine artery was the feeding artery of the lesion, and it was embolized with n-butyl cyanoacrylate. Four months postoperatively, epistaxis stopped and a computed tomography scan showed shrinkage of the mass.</p><p>Conclusion: Embolization alone for an organized hematoma is a treatment option in patients with no symptoms other than epistaxis and high surgical risk.</p>
