Blood vessels were seen in large number at the periphery of the lesion [ Figure 5 ]. No encapsulation was noted [ Figure 4 ]. Invasion of the intracranial region may lead to cranial nerve palsy. Srivalli Madhira 1 Department of E. The smaller vessels in the central portion of the lesion typically lack muscular elastic laminae and the absence of muscular coat contributes to the angiofibrima for massive bleeding that occurs with JNA [ 3 ].

The color depends on the vascular component and may vary from pale white in less vascular lesions to a pink and wine colored mass in highly vascularized ones. This approach with partial medial maxillectomy can give good exposure of pterygopalatine fossa and easy manipulation of maxillary artery. He also complained of difficulty in breathing since 6—7 months. Hence early diagnosis not only helps in better management but also prevents recurrence of JNA. Thank you for updating your details.
When diagnosed early the patients are treated with a combination of preoperative embolization and surgical resection providing a good prognosis.

Case 1 Case 1. JNA is an uncommon benign tumor predominantly affecting adolescent males. Sagittal section in computed tomography scans showing site and extent of the lesion. Although benign, it is a locally aggressive tumor and invades the surrounding tissues and even bone through pressure resorption. J Otolaryngol Head Neck Surg.
A history of head ache was angiodibroma by 6 patients case nos. Two patients case nos. Otolaryngol Head Neck Surg. Thus, early diagnosis, accurate staging and adequate treatment are essential in the management of this lesion.
Acknowledgments Conflict of interest None. In this location, it produces widening of the pterygopalatine fossa, inferior orbital and pterygomaxillary fissures and bowing of the posterior wall of the maxillary antrum. Hence the patient can take oral feeds early and with less morbidity.
Other patients either refused or could not afford preoperative bella. Prognosis for nasopharyngeal angiofibroma nasotaring favorable. It was mucoid to mucopurulent. A detailed history followed by thorough clinical examination of head and neck region was done. Angiography is a useful adjunct in the diagnosis of vascular tumors.
Mesothelioma Malignant solitary fibrous tumor. You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. Conflicts of interest There are no conflicts of interest.
True maxillary sinus involvement was not seen in any patient but soft tissue density seen on CT scan in case nos. One patient with stage IIA disease case no. Continuous growth involves the sphenoidal sinus, nasal fossa and middle turbinate, pterygomaxillary fossa and the posterior wall of the maxillary sinus as seen in the present case.
The patients were treated surgically using various surgical approaches like trans-palatal, endoscopic trans-nasal, lateral rhinotomy and trans-maxillary approach depending on their JNA stage. Principally four approaches were used in this study. Case 5 Case 5.

Overlying mucosa appeared normal. The main clinical presentation of JNA is unilateral nasal obstruction with or without epistaxis.
Nasopharyngeal angiofibroma – Wikipedia
The presentation is typically with obstructive symptoms, epistaxisand chronic otomastoiditis due to obstruction of the Eustachian tube. Thus this approach is best utilized for JNA confined to nasopharynx and sphenoid sinus. This may be attributed to a rich vasculature and lack of encapsulation. Diagnostic and therapeutic management. This approach obviates the need for any skin incision and hence angiofirboma cosmetic defect is expected.
Nasal cavity Esthesioneuroblastoma Nasopharynx Nasopharyngeal carcinoma Nasopharyngeal angiofibroma Larynx Laryngeal cancer Laryngeal papillomatosis.
JNA classically presents as a painless, progressive unilateral nasal obstruction. Nasal Cavity extension of JNA was seen in 10 patients with attachments to posterior end of turbinates in 8 cases and posterior end of septum in 2 patients.
