Of 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.

Arch Pathol Lab Med ; However, as in any invasive procedure, embolization presents risks that should be fully explained to the patients The presentation is typically with obstructive symptoms, epistaxisand chronic otomastoiditis due to obstruction of the Eustachian tube.

The first description of an endoscopic resection was published in Many studies highlight the benefit of preoperative arterial embolization to control bleeding intraoperative 16 29 By using this site, you agree to the Terms of Use and Privacy Policy. Studies comparing surgical treatment with or without embolization have shown that preoperative embolization reduced intraoperative blood loss and the need for replacement of blood products 31 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 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 3 patients who underwent combined surgeries experienced intraoperative bleeding, requiring nasal packing and replacement of blood products during surgery. Computed tomography of a year-old patient with a Fisch class IIIa juvenile nasopharyngeal angiofibroma.

Biopsy should be avoided as to avoid extensive bleeding since the tumor is composed of blood vessels without a muscular coat.

In the 17 patients who underwent endoscopic approach alone, the mean operation angiofiboma was min and the mean blood loss was mL; none required replacement of blood products. 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 Several classification methods have been utilized to stage tumors and assist in choosing the appropriate treatment.

The first patient who underwent surgery in our department had a Fisch I tumor, but did not undergo embolization or clamping of the external carotid arteries.

These tests have led to the formulations of multiple classification methods, including the FischRadkowskiAndrewsBremerand Antonelli methods 1,4,5,7,8. Classification of Fisch Type I: The mean operation time was min, and the mean bleeding volume was mL. Ideally, the time between the completion of embolization and the endoscopic procedure should be as small as possible, approximately h Find articles by Eduardo Passos Fiel de Jesus.
