Exclusively endoscopic removal of juvenile nasopharyngeal angiofibroma: In the 17 patients who underwent endoscopic approach alone, the mean operation time was min and the mean blood loss was mL; none required replacement of blood products.

External carotid clamping has been shown to assist in hemostasis of the tumor. Patients undergoing embolization require external carotid clamping due to collateral circulation, which can increase bleeding. Removal anfiofibroma important in preventing nasal obstruction and recurrent epistaxis.

Pathology Outlines – Nasopharyngeal angiofibroma

Surgery difficult to excise juvenol, preoperative embolization or antiandrogen therapy Chemotherapy or radiation therapy if advanced or aggressive. Since then, several cases have been reported, all showing that endoscopic resection resulted in lower morbidity during the early stages of disease The development of minimally invasive techniques has led to the increased use of endoscopic surgery for the treatment of nasopharyngeal angiofibroma 21making it ideal for hasofaringeo confined to the nasopharynx, nasal cavity, and sphenoid sinus with minimal extension into the pterygopalatine fossa 10,12,13,15,18, Tumour of the respiratory system.

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.

A biopsy is recommended only in cases of diagnostic uncertainty4. Conclusion 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.

Patients were aged 10—29 years. Improvements in surgical techniques are designed to shorten surgical time and thereby juvvenil patient morbidity. The tumor is primarily excised by external or endoscopic approach. Embolization of a year-old patient with a Fisch IIIa nasofaringro nasopharyngeal angiofibroma.

Nasopharyngeal angiofibroma also called juvenile nasopharyngeal angiofibroma [1] [2] is a histologically benign but locally aggressive vascular tumor that grows in the back of the nasal cavity. Find articles by Eduardo Passos Fiel de Jesus.

However, most authors agree that JNAs arise from the posterior choanal tissues in the region of the sphenopalatine foramen. Angkofibroma Radiotherapy for Juvenile Nasopharyngeal Angiofibroma.

Of our 20 patients, 3 required a combination of endoscopic and open surgery, with one, with a Fisch IIIA tumor, having expanded Caldwell-Luc and endoscopic techniques; one, with a Fisch IIIA tumor, undergoing mid-facial degloving and endoscopic surgery; and one, with a Fisch IVA tumor, having mid-facial degloving, craniotomy, and endoscopic surgery Figure 4.

Angiofibroma nasofaríngeo juvenil

Pathogenisis of Juvenile Nasopharyngeal Fibroma A new concept. 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.

All patients were male, and all had nadofaringeo of progressive nasal obstruction and recurrent epistaxis.

These classification systems are based on examination methods, including CT, MRI, and endoscopy, and have been utilized to establish the extent of the tumor, its pattern of spread, and consequently, surgical planning 10,11,12,16,17,18, Endoscopic Ressection of Juvenile Angiofibroma: The second patient, also with a Fisch I tumor, underwent clamping of the external carotid arteries without embolization. Some surgeons, however, do not routinely perform embolization preoperatively, finding that embolization is justified only in larger tumors Received Aug 21; Accepted Oct 7.

Oronasal fistula a possible complication of preoperative embolization in the management of juvenile nasopharyngeal angiofibroma. External carotid clamping has been shown to assist in hemostasis of the tumor. From a triangular region formed by the foramen ovale, a round and lacerated tumor may reach the middle fossa, migrating to the parasellar region and remaining generally extradual and lateral to the cavernous sinus.

Discussion Juvenile nasopharyngeal angiofibromas present almost exclusively in men aged years Endoscopic surgery alone or with other conventional techniques was safe for the treatment of angiofibromas of different stages.

The combination of different accesses to the tumor can be required 9. Moreover, the mean blood loss in these patients was mL. We analyzed findings in 20 patients who underwent surgery between and This may have been due to their relatively early diagnosis, when tumors are found smaller and easier to remove completely, as well as due to the use of endoscopic surgery, which assists in controlling tumor removal, including more accurate examinations of the spaces previously occupied by the tumor.
