Definition
Nasopharyngeal angiofibroma (NA) is a benign but locally aggressive fibrovascular tumor, which predominantly occurs in adolescent males.
Clinical Features
Incidence
NA is a rare tumor with an estimated incidence of 0.05–1% of all head and neck tumors (Boghani et al. 2013).
Age
Patients range in age between 10 and 25 years, with a mean of 17 years (Boghani et al. 2013).
Sex
It shows a clear predilection for adolescent male subjects.
Site
NA originates in the nasopharynx or less frequently in the posterior nasal cavity.
Treatment
The choice of the appropriate treatment is based on tumor extension (Yi et al. 2013). Surgical resection is currently accepted as the treatment of choice, and transnasal endoscopic approach is the main modality employed in early stage disease (Douglas and Wormald 2006). In cases with intracranial extension, endoscopic resection can be considered as approach to treatment (Leong 2013). A multimodality approach, with...
