Case Series of Pre-Operative Endovascular Embolization of Nasopharyngeal Angiofibroma Using Polyvinyl Alcohol Foam Particle: A Single Centre Experience

Nasopharyngeal Angiofibroma is a rare neoplasm in the sphenopalatine foramen. This tumour is histologically benign, but clinically malignant because it can erode the bone and surrounding structures, such as the pterygopalatine fossa, paranasal sinuses, and nasal cavity. It is a highly vascular tumour, sometimes from multiple Feeding arteries, and tends to bleed easily.
