Juvenile nasopharyngeal angiofibroma (JNA) is a benign, rare and highly vascular tumour, occurring in adolescent males. Clinical records of 27 patients who underwent surgical resection, performed between 1989 and 2017, were reviewed. Three patients were submitted to paralatero-nasal rhinotomy, 23 patients (85%), to the sublabial transnasomaxillary approach (Rouge Denker approach), complemented in 19 (70. Read More

A few studies have reported incomplete resection of juvenile nasopharyngeal angiofibroma (JNA) following embolization. The likely effects of embolization, viz. shrinkage/reduced tensile strength may have increased the fragility of tumour, leaving remnants postoperatively particularly across hour-glass constriction of sphenopalatine foramina.

Lesions involving the masseteric and buccal spaces have traditionally required transoral or transcervical approaches. Herein, the authors describe the successful endonasal endoscopic resection of a juvenile nasopharyngeal angiofibroma (JNA) with significant extension into the masseteric and buccal spaces facilitated by transoral finger retraction. Juvenile nasopharyngeal angiofibromas are hypervascular tumors originating in the pterygopalatine fossa (PPF) with complex relationships to skull base and orbital structures. Read More

Purpose: Approximately 20% of cancers are estimated to have a viral etiology. We aimed to investigate whether DNA of 8 human parvoviruses [bocavirus 1-4 (HBoV1-4), parvovirus B19 (B19V), protoparvoviruses (bufa-, tusa-, and cutavirus)] and 13 human polyomaviruses (HPyV) can be detected in oropharyngeal and oral cavity squamous cell carcinoma (OPSCC/OSCC), and in juvenile nasopharyngeal angiofibroma (JNA) tissue samples.

Methods: Fresh samples of seven JNA tissues and ten paired tissues of OSCC/OPSCC tumor and adjacent healthy tissues were collected. Read More

'Juvenile' nasopharyngeal angiofibroma, which accounts for <1% of all head and neck neoplasms, occurs predominantly in males between 10 and 18 years of age. The small number of patients older than 30 years confirms that presentation after this age is exceptional. Only rare cases of nasopharyngeal angiofibroma in female patients have been documented to date, and some authors believe that sex chromosome studies are indicated in such cases. Read More

Juvenile nasopharyngeal angiofibroma is a benign disease affecting young males with a propensity to invade intracranially and into the orbit along preformed pathways. Complete surgical excision is the mainstay of management. Patients with multiple recurrences along with tumour extension into skull base and orbit can be considered for external beam radiation as either adjuvant or definitive treatment. Read More

Objectives: Infratemporal fossa (ITF) tumors are rare and little is known about their general epidemiology, making it sometimes difficult for clinicians, who seldom encounter them, to distinguish between benign and malignant forms on the basis of the initial clinical and radiological work-up alone. The objectives of this retrospective study were: (i) to determine the respective prevalences of the various histologic types of ITF tumor, and (ii) to assess associations between certain clinical and radiological features and malignancy.

Methods: A single-center observational study in a university hospital included all new consecutive cases of ITF tumor treated from January 2000 to December 2016. Read More

Juvenile nasopharyngeal angiofibroma (JNA) is a hypervascular tumor and uncontrolled hemorrhage makes its removal very difficult. Although preoperative intravascular embolization of a feeding artery is recommended, serious complications such as iatrogenic thrombosis in the brain and insufficient decrease in blood flow to the tumor are concerns. Recently, coblation plasma technology has been reported to be useful for tumor removal with minimum hemorrhage under a clear surgical field. Read More

Background: Juvenile nasopharyngeal angiofibroma often attaches firmly to the adjoining bony region around the sphenopalatine foramina-sphenopalatine fossa-pterygomaxillary fissure. This can result in hourglass-shaped constriction and predispose to incomplete resection (residual disease) with a transpalatal approach. This paper describes attempts to address this 'inaccessible' area with a novel instrument, used since 2012. Read More

This article provides an organized foundation that facilitates the management of acute epistaxis and an understanding of features that merit further diagnostic workup. Prompt management, including measures such as holding pressure and using nasal packing, takes precedence over comprehensive diagnostic workup. Severe, recurrent, and posteriorly based bleeds should prompt consideration of alternate interventions and expert consultation. Read More

Objective: To examine the expression of hypoxia-inducible factor-1α (HIF-1α) and its related molecules (cellular repressor of E1A-stimulated genes [CREG], osteopontin [OPN], proto-oncogene tyrosine-protein kinase Src [c-Src], and vascular endothelial growth factor [VEGF]) in juvenile nasopharyngeal angiofibroma (JNA) and explore the correlation between clinical prognosis and HIF-1α expression.

Methods: The study performed a retrospective review of the clinical records of patients with JNA treated between 2003 and 2007. Specimens were analyzed by immunohistochemistry for HIF-1α, CREG, OPN, c-Src, and VEGF expression, and microvessel density (MVD) was assessed by tissue microarray. Read More

Juvenile nasopharyngeal angiofibroma is the most common benign tumor of the nasopharynx with complaints of unilateral nasal obstruction and recurrent nosebleeds in the young male population. Despite being a benign tumor, it can be aggressively destructive in surrounding tissues and bones by acting locally. The gold standard treatment method is the surgical excision of the tumor.
