However, these tumors are highly vascularized and grow rapidly. We analyzed findings in 20 patients who underwent surgery between and All 16 patients were submitted to primary surgical resection.

Other advantages include less surgical time, hospitalization, absence of visible scars, avoids complications such as epiphora, dysesthesia, trismus, and craniofacial deformities 2,5,14, The recurrence rate of endoscopically resected tumors has been shown to be low, and we found that none of our 20 patients experienced tumor recurrence.

Following two years there were two recurrences in patients with just two and three Figures 1 and 3. Tumor size was not associated with bleeding. The classic triad of epistaxis, unilateral nasal obstruction, and a mass in the nasopharynx suggests a diagnosis of nasopharyngeal angiofibroma and is supplemented by imaging 11,12,13,14, Juvenile nasopharyngeal angiofibroma JNA is a rare tumor in adolescent males.

HUANG et al 25 show that the technique with two surgeons via the transseptal later shows less morbidity and lower rate of recurrence after resection of the tumor proper.

We also found that patients who underwent clamping of the external carotid artery and embolization angiofibromq less intraoperative bleeding than patients who underwent embolization alone. Angiofibroma — rewiew of cases.

Evaluation of the effectiveness of preoperative embolization in surgery for nasopharyngeal angiofibroma. All 20 patients were available for follow-up maximum, 7 yearswith none showing evidence of tumor recurrence.

Nasopharyngeal angiofibroma: Our experience and literature review

Services on Demand Journal. Sarcoma Lymphoma Immature nasofariingeo Melanoma. All patients were classified radiologically and surgically according to the Fisch system. Since then, several cases have been reported, all showing that endoscopic resection resulted in lower nasfaringeo during the early stages of disease Surgical methods in all patients were based on Fisch classifications.

Article accepted in April 21, Patients undergoing embolization require external carotid clamping due to collateral circulation, which can increase bleeding. Its blood supply is done by the internal maxillary juvenill, may also be branches of the ipsilateral internal carotid artery 4,6. Several surgical approaches have been utilized for ansofaringeo 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.

Methods We analyzed 20 patients with nasopharyngeal angiofibroma who underwent surgery in the otolaryngology service between and It shows very aggressive behavior due to local invasiveness and is associated with various symptoms. 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.

None of these patients required postoperative nasal packing, and all were discharged the day after surgery. Am J Clin Oncol.

juvenl The remaining 17 patients, regardless of the tumor classification, underwent embolization and clamping of the external carotid arteries due to better control of bleeding during surgery. Preoperative embolization minimizes intraoperative blood loss.

The tumor invades the infratemporal fossa or orbit without intracranial involvement. Since then a number of cases were reported and all showed that endoscopic resection had a lower morbidity for the early stages of disease 2.

Nasopharyngeal angiofibroma

The second patient, also with a Fisch I tumor, underwent clamping of the external carotid arteries without embolization. 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.

Tumor recurrence in the long run has been a frustration.

Surgical approaches for conventional techniques include transpalatal, transmaxillary, lateral rhinotomy, mid-facial degloving, extended sublabial Denker, and Le Fort type I osteotomy 11,13,20, The overall recurrence rate was Pathogenisis of Juvenile Nasopharyngeal Fibroma A new concept.

The tumor invades the nasal sinuses or the pterygomaxillary fossa with bone destruction. Find articles by Arlete Cristina Granizo Santos.

Evaluation of the effectiveness of preoperative embolization in surgery for nasopharyngeal angiofibroma. Medical treatment and radiation therapy are only of historical interest. Of our 20 patients, only 2 underwent surgery without angioffibroma, with these 2 showing significantly greater intraoperative bleeding than the 18 patients who underwent embolization.

Many studies highlight the benefit of preoperative arterial embolization to control bleeding intraoperative 16 29 Current Management of juvenile nasopharyngeal angiofibroma: However, as in any invasive procedure, embolization presents risks that should be fully explained to the patients Recurrence in juvenile angiofibroma.
