Highlights • Hemangiomas are common benign vascular tumors of the head and neck region. However, they are not common to arise in the sinonasal mucosa.• Hemangioms have an average size of one centimeter and have been reported to be as large as 8 cm.• The endoscopic approach is the usual surgical approach in small size hemangiomas, while an open approach is more common with the larger size.• Preoperative embolization has been shown to be effective in decreasing tumor size and minimizing bleeding.
