Professor in the Department of Otolaryngology. In this study, we have described our experience in treating 20 patients with nasopharyngeal angiofibromas in the Department of Otorhinolaryngology.

Angiofibroma nasofaríngeo juvenil

Patients were aged 10—29 years. Case 4 Case huvenil. Find articles by Eduardo Passos Fiel de Jesus. These tumors occur almost exclusively in male adolescents and account for 0. Direct intratumoral embolization of juvenile angiofibroma.

Mortality is not associated with nasopharyngeal angiofibroma. Patients were aged years. Support Radiopaedia and see fewer ads. Antral sign or Holman-Miller sign forward bowing of posterior wall of maxilla is pathognomic of angiofibroma.

Nasopharyngeal angiofibroma

Factors analyzed include patient age and gender, symptoms, stages, treatment, length of surgery, intraoperatory bleeding, postoperative need for nasal tampons, hospitalization time, complications, and tumor recurrence.

Of our 20 patients, only 2 underwent surgery without clamping of the external carotid arteries, with both showing more bleeding than the nasfaringeo who underwent surgery with clamping. External carotid clamping has been shown to assist in hemostasis of the tumor.

Combined surgery consisting of a craniotomy, degloving, and endoscopic surgery in a patient with a Fisch IVA tumor. Oronasal fistula a possible complication of preoperative embolization in the management of juvenile nasopharyngeal angiofibroma. 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.

Removal is important in preventing nasal obstruction and recurrent epistaxis. The tumor is limited to the sphenopalatine foramen, nasopharynx, and nasal cavity without bone destruction.

Several classification methods have been utilized to stage tumors and assist in choosing the appropriate treatment. The recurrence rate of endoscopically resected tumors has juvrnil shown to be low, and we found that none of our 20 patients experienced tumor recurrence. Computed tomography of a year-old patient with a Fisch class IIIa juvenile nasopharyngeal angiofibroma.

CT of a year-old patient with a Fisch class II juvenile nasopharyngeal angiofibroma. Nasopharyngeal angiofibroma[TI] free full text[sb]. Endoscopic surgery alone or with other conventional techniques was safe for the treatment nsofaringeo angiofibromas of different stages.

Angiofibroma — rewiew of cases.

Although these masses are thought to arise jyvenil 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. The other 17 patients underwent endoscopic surgery alone. A comparative study of surgical approches. Am J Clin Oncol. From Wikipedia, the free encyclopedia. Medical treatment and radiation therapy are only of historical interest.

Angiofibroma – rewiew of cases. Case 3 Case 3. Pathogenisis of Juvenile Nasopharyngeal Fibroma A new concept. Patients undergoing embolization require external carotid clamping due to collateral circulation, which can increase bleeding. All patients were male, and all had symptoms of progressive nasal obstruction and recurrent epistaxis.

Tumors may invade the anterior fossa through the ethmoid and sphenoid sinuses, being more frequent in agiofibroma middle fossa and remaining extradural 8,9, All patients were male, and all had symptoms of progressive nasal obstruction and recurrent epistaxis. For example, a retrospective study of 15 patients found tumor recurrence in 1 patient 6.

The development of minimally invasive techniques has led to the increased use of endoscopic surgery for angiofiboma treatment of nasopharyngeal angiofibroma 21making it ideal for tumors confined to the nasopharynx, nasal cavity, and sphenoid sinus with minimal extension into the pterygopalatine fossa 10 12 13 15 18 Seventeen patients required clamping of the external carotids and tumor embolization.

Findings are similar to those described above. Several surgical approaches have been utilized for the 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.

Treatment trends in patients during 40 years. None of our patients experienced complications due to embolization.

None of these patients required postoperative nasal nasovaringeo, and all were discharged the day after surgery. DSA digital subtraction angiography of carotid artery to see the extension of tumors and feeding vessels. Surgery of cranial base tumors. Endoscopic surgery is less invasive than open surgery, causing less damage to the patient.

Juvsnil 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 Long-term tumor recurrence has been reported due to incomplete initial resection.

Imaging plays an important role in diagnosis, as biopsies should be avoided due to the risk of brisk hemorrhage, as well as staging. These classification systems are based on examination agiofibroma, 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 Conclusion Nasal endoscopy, alone juvrnil 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.
