【 摘 要 】

Organized hematoma (OH) is benign tumor in the maxillary sinus. The standard treatment for OH is complete surgical resection, however massive bleeding can occur during the procedure, albeit rarely. Some reports have suggested preoperative embolization is useful for reducing the volume of intraoperative bleeding. We report 3 cases of OH in the maxillary performed preoperative embolization. We identified the feeding arteries by angiography or IVR-CT, and we embolized them using Gelatin sponge particles. The embolized artery was the maxillary artery or both the maxillary and the facial artery. There were no major complications as a result of embolization. The mean fluoroscopy time was 35.8 minutes, and the mean fluoroscopy dose was 329.3 mGy. Tumor resection was performed the next day after arterial embolization. The mean bleeding volume for surgery was 383.3 ml, and the mean operative time was 194 minutes. No recurrence was observed in any of the cases over a 4-year follow-up period. We considered that it is possible that preoperative artery embolization is useful for decreasing intraoperative bleeding volume. Although the methods and usefulness of embolization await future reports, it is a technique that should be considered preoperatively because of its potential to prevent massive bleeding.
