Abstract

Nasopharyngeal angiofibroma occurs predominantly in adolescent males, and shows frequent epistaxis, nasal obstruction, mouth breathing and facial deformities. Because its recurrence rate ranges from 7.1% to 50%, complete removal of this tumor is important to prevent recurrence. Traditionally, many surgical approaches including lateral rhinotomy and transpalatal approaches have been used for this tumor depending on the site and size of the tumor. If the tumor is small and present within the nasal cavity, endoscopic approach can be used. But when tumor has extended to pterygopalatine fossa, endoscopic approach has some limitations for complete removal. In such a case, we have used a transantral microsurgery and transnasal endoscopic combined approach. We present two cases of nasopharyngeal angiofibromas treated by deep transantral microsurgery and intranasal endoscopic approach. By this approach, we have ligated the internal maxillary artery after emboliztion of intenal maxillary artery and could remove the tumor completely. Two patients have been followed over 12 months without recurrence.
