Association between vascular supply, stage and tumour size of juvenile nasopharyngeal angiofibroma

Juvenile nasopharyngeal angiofibroma (JNA) is a highly vascular tumour seen in adolescent males. To study the vascular pattern of these tumours, we retrospectively reviewed the records of patients with JNA who underwent preoperative angiography. Most (82.2 %) of the 45 patients assessed were Radkows...

Description
Summary:Juvenile nasopharyngeal angiofibroma (JNA) is a highly vascular tumour seen in adolescent males. To study the vascular pattern of these tumours, we retrospectively reviewed the records of patients with JNA who underwent preoperative angiography. Most (82.2 %) of the 45 patients assessed were Radkowski stage III with a mean size of 5.29 cm. There was a significant association between tumour stage and size ( p  = 0.029). Ten different vessels were seen to supply these tumours. All tumours had primary supply from the distal third of the ipsilateral internal maxillary artery (IMA). Accessory vessel supply was chiefly from the Vidian branch of internal carotid artery (ICA) (55.6 %). Stage III tumours were supplied by a greater number of feeding vessels than earlier stage tumours ( p
