The recurrence rate of endoscopically resected tumors has been shown to be low, and we found that none of our 20 jyvenil experienced tumor recurrence. Although nasal endoscopic surgery is safe, rapid, and effective, studies are needed to assess the importance of preoperative embolization and clamping of angioibroma external carotid artery in reducing intraoperative bleeding.
Factors analyzed include patient age and gender, symptoms, stages, treatment, length of surgery, intraoperatory bleeding, postoperative need for nasal tampons, hospitalization time, complications, and tumor recurrence.
Support Radiopaedia and see fewer ads. To minimize complications, surgery should be performed at centers with extensive experience.
