Nasopharyngeal angiofibroma: Our experience and literature review

The tumor invades the nasal sinuses or the pterygomaxillary fossa with bone destruction. Synonyms or Alternate Spellings: Improvements in surgical techniques are designed to shorten surgical time and thereby reduce patient morbidity. About Blog Go ad-free. Support Radiopaedia and see fewer ads.

The volume of intraoperative bleeding has been shown to be similar in patients with and without embolization 34whereas tendency to relapse was greater in patients undergoing embolization.

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. All patients were classified radiologically and surgically according to the Fisch system.

Patients were aged 10—29 years.

Transcatheter arterial embolization in nasopharyngeal angiofibroma. Endoscopic surgery is less invasive than open surgery, causing less damage to the patient. Patients may present with life-threatening epistaxis.

None of our patients experienced complications due to embolization. Intraoperative control of bleeding amgiofibroma the resection of nasopharyngeal angiofibromas can be achieved successfully by temporary clamping of the external carotid arteries in the neck Juvenile nasopharyngeal angiofibroma originates in the sphenopalatine forame, causing epistaxes and nasal obstruction. These tests have led to the formulations of multiple classification methods, including the FischR adkowskiA angiofjbromaB remerand A ntonelli methods 1 4 5 7 8.

CT is particularly useful at delineating bony changes.

Pathology Outlines – Nasopharyngeal angiofibroma

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. 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 iuvenil previously occupied by the tumor. The volume of intraoperative bleeding has been shown to be similar in patients with and without embolization 34whereas tendency to relapse was greater in patients undergoing embolization.

It is, as the name suggests, very vascular and a biopsy can sometimes be fatal. Juvenile nasofagngeo angiofibroma is a rare, highly vascular, and histologically benign tumor, generally observed in male adolescents.

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

Nasopharyngeal angiofibroma

The third patient with a Fisch I tumor underwent surgery with embolization, but without clamping of the external carotid arteries. Well circumscribed but unencapsulated polypoid fibrous mass, bleeds severely on manipulation and biopsy, may occlude nares Spongy cut surface.

nasofqrngeo Laterally, these tumors may extend to and fill the pterygomaxillary fossa, causing the posterior wall of the maxillary sinus to bulge and eroding the pterygoid plate.

Of our sngiofibroma patients, only 2 underwent surgery without embolization, with these 2 showing significantly greater intraoperative bleeding than the 18 patients who underwent embolization. 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, 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, These classifications are very important in helping surgeons decide the appropriate surgical approach.

However, most authors agree that JNAs arise from the posterior choanal tissues in the region of the sphenopalatine nazofarngeo. Laterally, these tumors may extend to and fill the pterygomaxillary fossa, causing the posterior wall of the maxillary sinus to bulge and eroding the pterygoid plate. Surgical methods in all patients were based on Fisch classifications. Moreover, the mean blood loss in these patients was mL.
