Angiofibroma juvenil

Surgery for excision of juvenile nasopharyngeal angiofibroma (JNA) carries the possibility of massive life-threatening haemorrhage. Anaesthetic management aims to maintain haemodynamic stability and reduce blood loss. This case series describes the application of the bundled approach as a multimodal blood loss prevention bundle (MBLPB). Twenty patients underwent 23 surgeries with MBLPB. The blood loss and the number of units of blood transfused were recorded. The surgeon satisfaction score was assessed. The median [interquartile range (IQR)] estimated blood loss was 1300 (650-2350) ml...

OBJECTIVE: To assess the microvascular density (MVD) in juvenile nasopharyngeal angiofibroma (JNA) with CD34 immunostaining and evaluate its relationship with clinico-demographic features. METHODS: This prospective study included patients with JNA undergoing endoscopic excision. The histopathological specimen was stained using CD-34 antibodies to calculate MVD. MVD and clinico-demographic features were correlated. RESULTS: The study included 12 patients with a median age of 15...

OBJECTIVES: Epistaxis is an emergency medical condition that sometimes requires admission to the emergency department. Pediatric epistaxis differs from epistaxis in the older population in terms of etiology, severity, and management. Our objective was to identify the distinctive features of pediatric epistaxis and determine the appropriate management. METHODS: This was a retrospective study of 231 medical records of children (<18 years old) with epistaxis of a total of 1171 cases in the general population who presented to our medical center's emergency department between 2013 and 2018...

We report the first case of a juvenile nasal angiofibroma (JNA) fed by multiple arteries from the internal carotid artery (ICA), removed without complications by temporarily blocking the ICA with two balloons. An early adolescent with JNA underwent preoperative embolisation of feeding arteries arising from the external carotid artery (ECA) (University of Pittsburgh Medical Centre classification IV). Endoscopic resection was attempted once but discontinued due to massive bleeding (7000 mL). 17 months later, the JNA had grown to fill both nasal cavities...

BACKGROUND: 3-Dimensional (3D) printing has proven its role in various fields. Recently, 3D printing has also been introduced in the otolaryngology domain. The nasopharynx, paranasal sinuses, and the anterior skull base have a complex anatomy. Critical structures must be delicately protected and preserved during a surgical procedure. It is, therefore, very important for the surgeon to have an excellent spatial understanding of the complex surgical field that is being traversed. CASE DESCRIPTION: Our case is of a 19-year-old male with a 2-month history of recurrent epistaxis, nasal blockage, and headache...

BACKGROUND: Anterior endoscopic access to middle cranial base lesions becomes feasible in the presence of infratemporal fossa (ITF) involvement. Various approaches, including endoscopic endonasal, transoral sublabial, and transorbital methods, have been described for accessing the ITF through a transmaxillary corridor. Among these approaches, endonasal access is the most commonly preferred, while the transorbital approach is a novel technique gaining popularity. The transoral sublabial approach is considered suitable for selected lesions...

Malignant tumors of the head and neck are rare in children, but it is important to know these lesions and identify them early in order to have a good outcome for these patients. Benign lesions of the head and neck are much more frequent and have an excellent prognosis. For this reason, it is necessary to recognize the warning signs and symptoms and understand when to refer the patient to a reference center for the treatment of these pathologies. The clinical presentation of both benign and malignant lesions in children may be similar as usually, both categories have compressive effects...

BACKGROUND: Juvenile Nasopharyngeal Angiofibroma (JNA) is a fibrovascular tumor of the nasopharynx that classically presents in adolescent males. The reported mean age of onset is between 13 and 22 years old [1-6]. Significant androgen stimulation is hypothesized to explain the strong predisposition for JNA to present in young adolescent males. However, considerable variability in age at diagnosis exists with rare involvement of very young patients incongruent with typical male pubertal growth patterns...

Angiofibroma also called juvenile nasopharyngeal angiofibroma are tumors of adolescence and the commonest site is the nasopharynx. Extra nasopharyngeal sites include upper respiratory and digestive tracts, oral cavity, tonsils, larynx, trachea, and esophagus. Intraosseous angiofibroma is the rarest of a rare entity.

BACKGROUND: Juvenile nasoangiofibroma (JNA) is a rare, highly vascular, locally aggressive benign tumor which affects male adolescents. It accounts for 0.05-0.5% of head and neck tumors with recurrence rates of 6-50%. The internal maxillary artery is the main source of JNA. OBJECTIVE: To evaluate the relationship between vascular supply as a factor associated with JNA recurrence. MATERIAL AND METHODS: An cohort study was performed in patients diagnosed with NAJ...

PURPOSE: To provide the first report on proton radiotherapy (PRT) in the management of advanced nasopharyngeal angiofibroma (JNA) and evaluate potential benefits compared to conformal photon therapy (XRT). METHODS: We retrospectively reviewed 10 consecutive patients undergoing PRT for advanced JNA in a definitive or postoperative setting with a relative biological effectiveness weighted dose of 45 Gy in 25 fractions between 2012 and 2022 at the Heidelberg Ion Beam Therapy Center...

Pituitary macroadenoma and angiofibroma are two distinct and diverse types of tumors that can develop in different anatomical locations and clinical characteristics and are not typically related to each other in terms of their hormonal or developmental aspects. This case describes an adult male with pituitary macroadenoma with nasal angiofibroma. A 35-year-old male was diagnosed with pituitary macroadenoma and incidentally found to have juvenile nasopharyngeal angiofibroma (NPA). The patient underwent a diagnostic workup, including imaging studies and hormonal assays, which confirmed the concomitant presence of both tumors...

BACKGROUND: The literature on microvessel density (MVD) signifying neoangiogenesis/tumour-activity in juvenile nasopharyngeal angiofibroma (JNA) is limited. Accordingly, this study evaluates and correlates MVD characteristics with clinical parameters/aggressiveness/recurrence. MATERIAL AND METHODS: Sixty-two paraffin blocks of JNA were studied histopathologically and MVD was assessed following immunohistochemistry using VEGF and CD34 as vascular markers. A clinical correlation of MVD was undertaken in 43 cases...

Background and Objectives : Juvenile nasopharyngeal angiofibroma (JNA) is an angiomatous hamartoma of the nasal cavity. It is a benign but locally aggressive vascular tumor of the nasopharynx affecting adolescent males. Many surgical procedures are in practice, but the extended endonasal endoscopic (EEE) approach for JNAs is a suitable and effective technique. Materials and Methods : Fifteen adolescent patients having JNA who underwent extended endonasal endoscopic (EEE) surgery from January 2010 to January 2022 were studied retrospectively...

Subglottic stenosis (SGS), the narrowing of the upper trachea, can be an acquired condition in pediatric patients. Presenting with varying degrees of dyspnea and stridor, acquired SGS is most commonly due to intubation. Airway stenosis is often not considered a surgical complication, and no literature on acquired SGS after endoscopic sinus surgery exists. We present a unique case of a 13-year-old male with juvenile nasopharyngeal angiofibroma (JNA), who developed SGS in the setting of progressive dyspnea six weeks after endonasal resection of his mass...

Neck masses are frequent in the pediatric population and are usually divided into congenital, inflammatory, and neoplastic. Many of these lesions are cystic and are often benign. Solid masses and vascular lesions are relatively less common, and the imaging appearances can be similar. This article reviews the clinical presentation and imaging patterns of pediatric solid and vascular neck masses.

PURPOSE: The Nordic countries (27 M) all have comparable, publicly funded healthcare systems, and the management of sinonasal tumours is centralised to the 21 university hospitals. We sought to assess and compare the treatment practice of sinonasal tumours across the Nordic countries. METHODS: A web-based questionnaire was sent to all university hospital departments of otorhinolaryngology-head and neck surgery in the Nordic countries. RESULTS: Answers were obtained from all 21 Nordic university hospitals...

An angiomatous nasal polyp is a rare subtype of sinonasal polyp that is commonly found in the middle meatus and characterized by the presence of blood vessels within polyp tissue. It is a benign lesion but is prone to misdiagnosis as a malignant tumor because it typically grows larger and is more vascular than other types of polyps. In this report, a 16-year-old male with no significant past medical history presents with a six-month history of epistaxis and progressive nasal obstruction. Examination of the oral cavity showed a centrally located soft palate mass...

A 54-year-old female presented to the otolaryngology (ENT) outpatient department with an eight-month history of unilateral nasal obstruction and headache. There was no change in the sense of smell, rhinorrhoea, facial pain, or associated epistaxis. On examination, there was a large, erythematous mass in the superior aspect of the right nasal cavity, filling the space between the nasal septum, middle, and superior meatus. The rest of the ENT examination was normal. Vital signs were all within the normal range...
