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. Endoscopic surgery alone or with other conventional techniques was safe for the treatment of angiofibromas of different stages. Consistent with previous results, we found that the mean operation time in the 17 patients who underwent endoscopic surgery alone was min Exclusively endoscopic removal of juvenile nasopharyngeal angiofibroma: All 20 patients were available for follow-up maximum, 7 yearswith none showing evidence of tumor recurrence.
To retrospectively describe our experience in the diagnosis and treatment of patients with juvenile nasopharyngeal angiofibroma. Intracranial juvenile nasopharyngeal angiofibroma.

Moreover, the mean blood loss in these patients was mL. Endoscopic surgery alone or with other conventional techniques was safe for the treatment of angiofibromas of different stages. This relatively low blood loss may be due to the use of surgical endoscopy, providing better control of bleeding than open surgery, with or without endoscopy.
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.
Intracranial extension can however occur.
Mortality is not associated with nasopharyngeal angiofibroma. It shows very aggressive behavior due to local invasiveness and is associated with various symptoms.
Case 6 Case 6. Recurrence in juvenile angiofibroma. Although these masses are thought to arise from the region of the sphenopalatine foramenthey are usually sizeable at diagnosis, frequently with extension medially into the nasopharynxlaterally into the pterygopalatine fossa and over time beyond, into the orbitparanasal sinusesintracranial cavity and infratemporal fossa. Support Center Support Center. Methods We analyzed 20 patients with nasopharyngeal angiofibroma who underwent surgery in the otolaryngology service between and Preoperative embolisation of tumour may be of some use in reducing intraoperative bleeding.
Patients were aged 10—29 years. Classification of Fisch Type I: Juvenile nasopharyngeal angiofibroma is a rare, highly vascular, and histologically benign tumor, generally observed in male adolescents.
Endoscopic Laser-assisted excision of juvenile nasopharyngeal angiofibromas.
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, Author information Article notes Copyright and License information Disclaimer.
Typically a lobulated non-encapsulated soft tissue mass is demonstrated centred on the sphenopalatine foramen which is often widened and usually bowing the posterior wall of the maxillary antrum anteriorly.
The presence of prominent flow voids lead to a salt and pepper appearance on most sequences and are juvrnil 5,6. Endoscopic Surgery for Juvenile Angiofibroma: Article accepted in October 7, We analyzed 20 patients with nasopharyngeal angiofibroma who underwent surgery in the otolaryngology service between and Open in a separate window.
Prognosis for nasopharyngeal angiofibroma is favorable. None of our patients experienced complications due to embolization. Surgical methods in all patients were based on Fisch classifications. Juvenile nasopharyngeal angiofibroma originates in the sphenopalatine forame, causing epistaxes and nasal obstruction.
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. The tumor invades the nasal sinuses or the pterygomaxillary fossa with bone destruction. 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. They account for only 0.
Variables analyzed included patient age, sex, symptoms, tumor stage, treatment, duration of surgery, volume of intraoperative bleeding, need for nasal packing after surgery, length of hospitalization, immediate and late complications, recurrence, and preoperative embolization and clamping of the external carotid during surgery.
Sociedade Brasileira de Otorrinolaringologia. Moreover, the mean blood loss in these patients was mL. Removal is important in preventing nasal obstruction and recurrent epistaxis. Unable to process the form. In addition, preoperative embolization may complicate the identification of the full extent of surgical margins by reducing the tumor size and increasing the risk of relapse The second patient, also with a Fisch I tumor, underwent clamping of the external carotid arteries without embolization.
Treatment trends in patients during 40 years. Endoscopic Ressection of Juvenile Angiofibroma: The 18 patients who underwent embolization did so h prior to surgery Figure 5.
However, these tumors are highly vascularized and grow rapidly. Some surgeons, however, do not routinely perform embolization preoperatively, finding that embolization is justified only in larger tumors Tumor size was not associated with bleeding.
