Juvenile Nasopharyngeal Angiofibroma
Updated: Aug 27, 2009
Introduction
Juvenile angiofibroma (JNA) is a benign tumor that tends to bleed and occurs in the nasopharynx of prepubertal and adolescent males.
History of the Procedure
Hippocrates described the tumor in the 5th century BC, but Friedberg first used the term angiofibroma in 1940. Other titles (eg, nasopharyngeal fibroma, bleeding fibroma of adolescence, fibroangioma) have also been used.
The image below depicts a coronal CT scan.
Coronal CT scan of the lesion filling the left nasal cavity and ethmoid sinuses, blocking the maxillary sinus and deviating the nasal septum to the right side.
Frequency
Juvenile nasopharyngeal angiofibroma (JNA) accounts for 0.05% of all head and neck tumors. A frequency of 1:5,000-1:60,000 in otolaryngology patients has been reported.
Sex
Juvenile nasopharyngeal angiofibroma (JNA) occurs exclusively in males. Females with juvenile nasopharyngeal angiofibroma (JNA) should undergo genetic testing.
Age
Onset is most commonly in the second decade; the range is 7-19 years. Juvenile nasopharyngeal angiofibroma (JNA) is rare in patients older than 25 years.
Etiology
The lesion originates in close proximity to the posterior attachment of the middle turbinate, near the superior border of the sphenopalatine foramen.
A hormonal theory has been suggested because of the lesion's occurrence in adolescent males.
Other theories include a desmoplastic response of the nasopharyngeal periosteum or the embryonic fibrocartilage between the basiocciput and the basisphenoid.
Etiology from nonchromaffin paraganglionic cells of the terminal branches of the maxillary artery has also been suggested. Comparative genomic hybridization analysis of these tumors revealed deletions of chromosome 17, including regions for the tumor suppressor gene p53 as well as the Her-2/neu oncogene.
Pathophysiology
The tumor starts adjacent to the sphenopalatine foramen. Large tumors are frequently bilobed or dumbbell-shaped, with one portion of the tumor filling the nasopharynx and the other portion extending to the pterygopalatine fossa.
Anterior growth occurs under the nasopharyngeal mucous membrane, displacing it anteriorly and inferiorly toward the postnasal space. Eventually, the nasal cavity is filled on one side, and the septum deviates to the other side. Superior growth is directed toward the sphenoid sinus, which may also be eroded. The cavernous sinus may become invaded if the tumor advances further.
Lateral spread is directed toward the pterygopalatine fossa, bowing the posterior wall of the maxillary sinus. Later, the infratemporal fossa is invaded. Occasionally, the greater wing of the sphenoid may be eroded, exposing the middle fossa dura. Proptosis and optic nerve atrophy result if orbital fissures are encroached upon by the tumor. Extranasopharyngeal angiofibroma is extremely rare and tends to occur in older patients, predominately in females, but the tumor is less vascular and less aggressive than juvenile nasopharyngeal angiofibroma (JNA).Presentation
Symptoms
- Nasal obstruction (80-90%) - Most frequent symptom, especially in initial stages
- Epistaxis (45-60%) - Mostly unilateral and recurrent; usually severe epistaxis that necessitates medical attention; diagnosis of angiofibroma in adolescent males to be ruled out
- Headache (25%) - Especially if paranasal sinuses are blocked
- Facial swelling (10-18%)
- Other symptoms - Unilateral rhinorrhea, anosmia, hyposmia, rhinolalia, deafness, otalgia, swelling of the palate, deformity of the cheek
Signs
- Nasal mass (80%)
- Orbital mass (15%)
- Proptosis (10-15%)
- Other signs include serous otitis due to eustachian tube blockage, zygomatic swelling, and trismus that denote spread of the tumor to the infratemporal fossa, decreasing vision due to optic nerve tenting (rare)
- Other causes of nasal obstruction, (eg, nasal polyps, antrochoanal polyp, teratoma, encephalocele, dermoids, inverting papilloma, rhabdomyosarcoma, squamous cell carcinoma)
- Other causes of epistaxis, systemic or local
- Other causes of proptosis or orbital swellings
