BackgroundNasopharyngeal angiofibroma is highly vascular and aggressive tumor seen commonly seen in adolescent males. Per-operative bleeding is major concern for surgical treatment of the tumor. There are many methods of preoperative reduction of tumor vascularity, including trans-arterial embolization. This study was aimed to find out surgical outcome of nasopharyngeal angiofibroma following transarterial embolization.

MethodsRetrospective review of medical records of patients who underwent transarterial embolization prior to surgery for nasopharyngeal angiofibroma between April 2013 and August 2017 was done. Demographics, presenting complaints, tumor stage, arteries embolized, embolizing agent used and amount of blood loss were recorded.

Results: Twelve patients, all male mostly in adolescence underwent preoperative embolization with gelatin sponge particles. More than half of the cases were Fisch stage I with only case being stage IV. Unilateral internal maxillary was embolized in all cases except for in stage IV patient in whom besides bilateral internal maxillary artery, ascending pharyngeal artery was also embolized. Blood loss ranged from 100 ml to 1300 ml with maximum blood loss in stage IV patients. 

ConclusionPreoperative transarterial embolization with particles are safe and efficient method of reducing intraoperative blood loss in patients undergoing surgery for nasopharyngeal angiofibroma.
