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.

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. Similarly, our patients ranged in age from 10 to 29 years, with a mean age of 16 years, and all were male. Blood loss, which was mL in a non-embolized patient, was reduced to mL in embolized patients Transcatheter arterial embolization in nasopharyngeal angiofibroma.

Angiofibroma nasofaríngeo juvenil

None of our patients experienced complications due to embolization. They may be locally aggressive.

Endoscopic surgery is less invasive than open surgery, causing less damage to the patient. Exclusively nasofarlngeo removal of juvenile nasopharyngeal angiofibroma: Nasofarigneo the 20 patients, 3 had surgery by combined approaches conventional and endoscopicincluding 1 patient with a Fisch IIIA tumor who was treated by the Caldwell-Luc expanded technique and endoscopic surgery, 1 patient with a Fisch IIIA tumor who was treated by the degloving mid-facial technique and endoscopic surgery, and 1 with a Fisch IV tumor who was treated by the degloving mid-facial technique associated with craniotomy and endoscopic surgery.

Prognosis for nasopharyngeal angiofibroma is favorable. Plain radiographs no longer play a role in the workup of a suspected juvenile nasopharyngeal angiofibroma, however juuvenil may still be obtained in some instances during the assessment of nasal obstruction, or symptoms of sinus obstructions.

Case 2 Case 2.

The tumor is limited to the sphenopalatine foramen, nasopharynx, and nasal cavity without bone destruction. Nasopharyngeal angiofibroma is a histologically and biologically benign tumor with aggressive behavior due to its location and associated symptoms including significant epistaxis and nasal obstruction 1 2 3 4 5.

Nasopharyngeal angiofibroma: Our experience and literature review

Preoperative embolisation of tumour may be of some use in reducing intraoperative bleeding. It most commonly affects adolescent males and may grow into fissures of the skull and may spread to adjacent structures.

Endoscopic Laser-assisted excision of juvenile nasopharyngeal angiofibromas. 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 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.

Classification of Fisch Type I: It angioffibroma, as the jjvenil suggests, very vascular and a biopsy can sometimes be fatal. The tumor invades the infratemporal fossa or orbit without intracranial involvement. Examinations such as computed tomography, nuclear magnetic resonance and even nasal endoscopy can clearly establish the extent of the tumor, its pattern of spread, and consequently, surgical planning 10,11,12,16,17,18, Nasofarineo example, a retrospective study of 15 patients found tumor recurrence in 1 patient 6.
