All patients were treated surgically, including 17 who underwent endoscopic surgery.

Strayer; Emanuel Rubin Endoscopic surgery is less invasive than open surgery, causing less damage to the patient. Consistent with previous results, we found that the mean operation time in the 17 patients who underwent endoscopic surgery alone was min The second patient, also with a Fisch I tumor, underwent clamping of the external carotid arteries without embolization. Jasofaringeo Juvenile nasopharyngeal angiofibromas present almost exclusively in men aged 14—25 years 23 24 25 26 27 From Wikipedia, the free encyclopedia.

Nasopharyngeal angiofibroma is a histologically and jvuenil benign tumor with aggressive behavior due to its location and associated symptoms including significant epistaxis and nasal obstruction Treatment trends in patients during 40 years. These classifications are very important in helping surgeons decide the appropriate surgical approach.

Nasal endoscopy, alone or combined with open techniques, was safe for the resection of angiofibromas at different stages, with low morbidity and high efficacy, as shown by complete tumor removal and low recurrence rates. Endoscopic Surgery for Juvenile Angiofibroma: Studies comparing surgical treatment with or without embolization have shown that preoperative embolization reduced intraoperative blood loss and the need for replacement of blood products 31, The volume of intraoperative bleeding has been shown to be similar in patients with and without embolization 34whereas tendency to relapse was greater in patients undergoing embolization.

They may extend towards the nasopharynx, which includes the maxillary, ethmoid, and sphenoid sinuses. Click here for patient related inquiries. Seventeen patients required clamping of the external carotids and tumor embolization. The tumor is primarily excised by external or endoscopic approach. Am J Clin Oncol. Similarly, our patients ranged jjvenil age from 10 to 29 years, with a mean age of 16 years, and all were male.

CT is particularly useful at delineating bony changes. Of our 20 patients, only 2 underwent surgery without embolization, with these 2 showing significantly greater intraoperative bleeding than the 18 patients who underwent embolization.

Juvrnil is marked contrast enhancement following administration of contrast, reflecting the prominent vascularity. All 20 patients were available for follow-up maximum, 7 yearswith none showing evidence of tumor recurrence.

These tumors occur almost exclusively in male adolescents and account for 0.

Of our 20 patients, only 2 underwent surgery without clamping of the external carotid arteries, with both showing more bleeding than the 18 who underwent surgery with clamping.

The tumor invades the infratemporal fossa or orbit without intracranial involvement.

Longer duration of surgery is associated with greater changes in body homeostasis due to surgical trauma. Sociedade Brasileira de Otorrinolaringologia.

If nasopharyngeal angiofibroma is suspected based on physical examination a smooth vascular submucosal mass in the posterior nasal cavity of an adolescent maleimaging studies such as CT or MRI should be performed. This page was last edited on 29 Septemberat The first patient who underwent surgery in our department had a Fisch I tumor, but did not undergo embolization or clamping of the external carotid arteries.

We analyzed findings in 20 patients who underwent surgery between and Endoscopic Ressection of Juvenile Angiofibroma: The recurrence rate of endoscopically resected tumors has nsofaringeo shown to be low, angiofubroma we found that none of our 20 nssofaringeo experienced tumor recurrence.

To retrospectively describe our experience in the diagnosis and treatment of patients with juvenile nasopharyngeal angiofibroma. Several surgical approaches have been utilized for angiofibroka removal of nasopharyngeal angiofibromas, including transnasal, transpalatal, transzygomatic, and transcervical accesses, in addition to lateral rhinotomy and mid-facial degloving, with or without extension to the upper lip or concomitant craniotomy 9.

Although nasal endoscopic surgery is safe, rapid, and effective, studies are needed to assess the importance of preoperative embolization and clamping of the external carotid artery in reducing intraoperative bleeding. Irradiation may be an option if surgery is not possible or only incomplete resection achieved 2,4,6.
