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...

Juvenile nasopharyngeal angiofibroma (JNA) is a highly vascular tumour seen in adolescent males. To study the vascular pattern of these tumours, we retrospectively reviewed the records of patients with JNA who underwent preoperative angiography. Most (82.2 %) of the 45 patients assessed were Radkowski stage III with a mean size of 5.29 cm. There was a significant association between tumour stage and size (p = 0.029). Ten different vessels were seen to supply these tumours. All tumours had primary supply from the distal third of the ipsilateral internal maxillary artery (IMA)...

BACKGROUND: Juvenile nasopharyngeal angiofibroma (JNA) has witnessed a four-fold increase in the incidence at our facility in the current decade as compared to the 1980s. With high global incidence of human pappilloma virus (HPV) related oropharyngeal cancer in India, we hypothesize its implication in JNA as it has not yet been reported. METHODS: Clinico-Surgical variables of 6 patients of JNA were included for correlation and their tissue samples were subjected to western blotting (WB), polymerase chain reaction and immunoflorescence to demonstrate a definite association with HPV...

BACKGROUND: Surgical approaches for many tumours are often limited by blood loss, exposure and risk to vital anatomical structures. Therefore, the standard of care for certain skull base tumours has become endoscopic transnasal resection. Other surgical disciplines often use cell salvage techniques, but review of the otolaryngology literature revealed very few case reports. This study investigated the value and safety of salvage-type autologous blood transfusion during the endoscopic resection of juvenile nasopharyngeal angiofibromas (JNA)...

OBJECTIVES: Endoscopic resection has become an established surgical option for most juvenile nasopharyngeal angiofibromas (JNA). However, surgical management of JNA with intracranial extension remains challenging. This retrospective multicenter study reviews a series of patients with advanced stage JNA treated via endonasal/endoscopic approach. METHODS: The experience of five academic tertiary or quaternary care ORL-HNS Departments were included. Medical records of all patients operated for JNA staged as Radkowski stage IIIA or IIIB were reviewed...

This report describes the third case of a true bilateral Juvenile nasopharyngeal angiofibroma (JNA), i.e. two separate JNA arising from both sides simultaneously. The associated multiple recurrences in such a case have not yet been reported. A 21-year-man underwent transpalatal excision and recurred twice. The last 'neo-occurrence' encountered after 2 years was at a different site and was subsequently managed by post-embolization endoscopic resection. A complete report of its clinico-radiological features and management outcome is discussed...

A recent case of advanced, recurrent juvenile nasopharyngeal angiofibroma (JNA) at our institution has highlighted the limited evidence regarding adjunctive treatment. We present the case of a 10-year-old boy who is the first to undergo multiple-staged surgical resections alongside vincristine treatment. We performed a review of the literature analyzing the roles of radiation therapy, cytotoxic drugs, and novel targeted agents in JNA relapse. Small cohort studies suggest radiotherapy and flutamide are the most rational treatment options for residual and recurrent JNA...

Several benign and malignant mesenchymal and meningothelial lesions may preferentially affect or extend into the sinonasal tract. Glomangiopericytoma (GPC, formerly sinonasal-type hemangiopericytoma) is a specific tumor with a predilection to the sinonasal tract. Sinonasal tract polyps with stromal atypia (antrochoanal polyp) demonstrate unique histologic findings in the sinonasal tract. Juvenile nasopharyngeal angiofibroma (JNA) arises from specialized tissue in this location. Meningioma may develop as direct extension from its intracranial counterpart or as an ectopic tumor...

Juvenile nasopharyngeal angiofibroma (JNA) is a benign vascular tumor occurring in young males. Treatment of JNA is a complex procedure, especially in advanced cases with a high risk of major complications. We report the clinical, radiological and histological specialties of a rare case of recurrent JNA 3 years after radiation therapy in an 18-year-old boy. The patient underwent endoscopy assisted partial midfacial degloving approach. This treatment has been shown to be effective in advanced JNAs with minor morbidity...

OBJECT Juvenile nasopharyngeal angiofibromas (JNAs) are formidable tumors because of their hypervascularity and difficult location in the skull base. Traditional transfacial procedures do not always afford optimal visualization and illumination, resulting in significant morbidity and poor cosmesis. The advent of endoscopic procedures has allowed for resection of JNAs with greater surgical freedom and decreased incidence of facial deformity and scarring. METHODS This report describes a graduated multiangle, multicorridor, endoscopic approach to JNAs that is illustrated in 4 patients, each with a different tumor location and extent...
