The management of juvenile nasopharyngeal angiofibroma has undergone a significant evolution, with more surgeons moving towards the minimal invasive endoscopic approaches. Although considered the standard of care by most, an endoscopic approach may not be sufficient for extensive tumours, as exemplified by the current case of a young man presenting with the largest juvenile nasopharyngeal angiofibroma described in English literature until the present that was eventually excised via an anterior external approach...

BACKGROUND: Juvenile nasopharyngeal angiofibroma (JNA) is a benign tumor that presents in adolescent males. Although surgical excision is the mainstay of treatment, recurrences complicate treatment. There is a need to develop less invasive approaches for management. JNA tumors are composed of fibroblasts and vascular endothelial cells. We identified fibroblast growth factor receptor (FGFR) and vascular endothelial growth factor (VEGF) expression in JNA-derived fibroblasts. FGFR influences fibroblast proliferation and VEGF is necessary for angiogenesis...

OBJECTIVE: A modern imaging review is necessary to further define the anatomic origin of the juvenile nasopharyngeal angiofibroma. METHODS: After institutional review board approval, a search from January 1998 to January 2013 yielded 33 male patients (aged 10-23 years) with pathologically proven juvenile nasopharyngeal angiofibroma lesions, as well as pretreatment computed tomography/magnetic resonance imaging. Juvenile nasopharyngeal angiofibroma involvement was assessed in the following regions: sphenopalatine foramen, pterygopalatine fossa, vidian canal, nasopharynx, nasal cavity, sphenoid sinus, choana, pterygomaxillary fissure/masticator space, orbit, and sphenoid bone...

Juvenile nasopharyngeal angiofibroma is tumour almost exclusively seen in adolescent males, constituting less than 1% of all neoplasms in head and neck. They are benign and locally spreading and are highly vascular in nature and thus prove to be a surgical challenge because of its complex anatomical location. Here, we present a case report of a 18-year-old male presenting with a mass in his left nasal cavity, with recurrent epistaxis and nasal obstruction. Computed tomography imaging revealed a non-encapsulated lobulated heterogeneous mass lesion in the naso-pharynx and left posterior choana of the nasal cavity, extending to pterygopalatine and infratemporal fossa, masseter space of left side...

Juvenile nasopharyngeal angiofibroma is a locally aggressive benign tumour which has propensity to erode the skull base. The tumour spreads along the pathways of least resistance and is in close proximity to the extracranial part of trigeminal nerve. Advancements in expanded approaches for endoscopic excision of tumours in infratemporal fossa and pterygopalatine fossa increase the vulnerability for the trigeminocardiac reflex. The manipulation of nerve and its branches during tumour dissection can lead to sensory stimulation and thus inciting the reflex...

Angiofibromas are rare, benign, but locally aggressive vascular tumours which account for 0.05-0.5% of all head and neck neoplasms. The common variant of angiofibromas of head and neck region is Juvenile Nasopharyngeal Angiofibroma (JNAF) which is well published in the literature. Incidence of Extranasopharygeal Angiofibromas (ENAF) is relatively rare and most of the published literature favours maxillary sinus as the most common site. We report a rare clinical entity of ENAF involving the upper lip which is first of its kind in the light of literature review owing to its anatomical location...

The current WHO classification system for tumors of the head and neck has made few changes from the previous edition with regards to tumors of the nasopharynx. The classification system is discussed here with particular attention to nasopharyngeal carcinoma, nasopharyngeal papillary adenocarcinoma, salivary gland anlage tumor, hairy polyp, juvenile angiofibroma, and other tumors.

Imaging plays an important role in the diagnosis, staging and prognosis of JNA. Certain radiological changes as seen on CECT were observed to be consistent in our case series. This study analysed preoperative and postoperative CECT of large series of JNA patients to evaluate the sites and pattern of spread of tumor. We evaluated the clinical significance of pterygoid wedge in preoperative and postoperative imaging and thus elucidating two new radiological signs. Retrospective analysis of the pre operative and post operative imaging data of 242 patients with JNA...

The extranasopharyngeal angiofibroma is a separate clinical entity but those involving infratemporal fossa and cheek resemble juvenile nasopharyngeal angiofibroma (JNA) and hence have been labelled as juvenile perinasal angiofibroma (JPA) in this paper. This paper presents a 7th case of JPA and attempts to review the world literature on JPA, along with a proposal of staging the disease. A 16 year male presented with a painless compressible facial swelling since 7 months without any epistaxis or nasal obstruction...

The role of preoperative embolization in alleviating intra operative haemorrhage in small to medium sized JNA is dubious. We report an unusual case of JNA who developed cerebral edema, hemiplegia and aphasia following glue embolisation and underwent frontotemporal craniectomy. This drastic aftermath of embolisation challenges the safety of preoperative embolisation in such lesions.

We describe a case of a 24-year-old male presenting urgently with a juvenile nasopharyngeal angiofibroma (JNA) with difficulty breathing, inability to swallow, and respiratory distress following throat swelling. The swelling was reduced with administration of dexamethasone and the JNA was surgically resected within 48 hours. This presentation was atypical given the acuity of presentation and the patient's older age.

Juvenile nasopharyngeal angiofibroma (JNA) is a rare benign tumor arising predominantly in the nasopharynx of adolescent males. It is an aggressive neoplasm and shows a propensity for destructive local spread often extending to the base of the skull and into the cranium. Clinically, however, it is obscure with painless, progressive unilateral nasal obstruction being the common presenting symptom with or without epistaxis and rhinorrhea. Diagnosis of JNA is made by complete history, clinical examination, radiography, nasal endoscopy and by using specialized imaging techniques such as arteriography, computer tomography and magnetic resonance imaging...
