          Abstract

          RESUMEN Introducción: El fibroangioma nasofaríngeo juvenil es un tumor vascular benigno localmente agresivo, que afecta casi exclusivamente la nasofaringe de adolescentes de sexo masculino. Su manejo es complejo dada su extensión, naturaleza vascular y sus frecuentes recurrencias. Objetivo: Mostrar la experiencia de 15 años en fibroangioma juvenil en nuestro centro. Material y método: Estudio descriptivo retrospectivo de los pacientes con diagnóstico de ingreso de fibroangioma nasofaríngeo juvenil al Servicio de Otorrinolaringología del Hospital Barros Luco Trudeau entre los años 1997 y 2011, caracterizando al grupo de estudio en cuanto a características clínico-demográficas, vasos aferentes, relación entre etapa tumoral y vascularización, manejo terapéutico, complicaciones y recurrencias. Resultados: Se obtuvo un total de 20 pacientes, todos de sexo masculino, con un promedio de edad de 13,9 años. El síntoma de presentación más frecuente fue la epistaxis a repetición y obstrucción nasal presente en el 90% y 80%, respectivamente. Todos los pacientes se estudiaron con tomografia computarizada y recibieron embolización arterial preoperatoria. La mayoría de los tumores fueron de tipo II (65%) y III (20%), según clasificación de Radkowski. La técnica quirúrgica más empleada fue abierta (57,8%). Radioterapia en un caso. El vaso aferente principal fue la maxilar interno ipsilateral en el 100%. Todos los fibroangiomas etapa III eran además irrigados por la arteria carótida interna. Se encontró 20% de persistencia y 15% de recidiva. Conclusión: Nuestros resultados concuerdan con la gran mayoría de las series publicadas en la literatura. Epistaxis recurrente, obstrucción nasal y tumor nasal unilateral deben hacernos sospechar de esta patología en un adolescente masculino. El tratamiento de elección es la cirugía con embolización preoperatoria. La vía de abordaje endoscópica presenta menor morbilidad posoperatoria en pacientes con estadios I y II de Radkowski. Todos los fibroangiomas con compromiso intracraneano, presentan irrigación también del sistema carotideo interno.

          ABSTRACT Introduction: Nasopharyngeal Fibroangioma is a locally aggressive benign vascular tumor. Its management is complex given its size, vascular nature and its frequent recurrences. Aim: To show the experience of 15 years in Juvenile Fibroangioma in our center. Material and method: Retrospective descriptive study of patients admitted with a diagnosis of Juvenile Fibroangioma Nasopharyngeal in the Department of Otolaryngology Hospital Barros Luco Trudeau between 1997 and 2011. Results: A total of 20 patients was obtained. The most common presenting symptom was recurrent epistaxis and nasal obstruction present in 90% and 80% respectively. The most common surgical technique was open (57.8%). Radiotherapy in one case. The main afferent vessel was the ipsilateral internal maxillary in 100%. All Fibroangioma stage III were also supplied by the internal carotid artery. 20% of persistence and 15% of recurrence was found. Conclusion: Recurrent epistaxis, nasal obstruction and unilateral nasal tumor should raise the suspicion of this disease in a male teenager. The treatment of choice is surgery with preoperative embolization. The route of endoscopic approach has less postoperative morbidity in patients with stage I and II of Radkowski. All Fibroangioma with intracranial commitment, have also the internal carotid irrigation system.

          Juvenile nasopharyngeal angiofibroma: a revised staging system.

          To discuss the shortcomings of current staging systems and to suggest modifications according to new surgical methods and data. A retrospective chart review. The medical records of 36 patients, all of whom underwent resection of juvenile nasopharyngeal angiofibroma by external or endonasal approach between 1983 and 2002, were reviewed retrospectively. Follow-up period of patients ranged from 3 to 7 years (mean, 4.5 years). Tumour extent, sites and rate of persistent disease were analyzed and compared with the literature. Persistent or recurrent disease was found in 12 of the 36 patients (33%). The primary tumour of these 12 cases invaded one or more anatomic region beside nasopharynx: the base of the pterygoid process in 9 cases (75%), the infratemporal fossa in 4 (33%), the pterygomaxillar fossa in 4 (33%), and the sphenoid sinus in 2 cases (17%). Involvement of the pterygoid process base was observed in only 3 of the 24 patients without persistent disease, whereas it was found 10 out of 12 patients with persistent disease. Advances in radiographic imaging, embolization, and surgical methods of treating angiofibromas have changed the sites associated with a high risk for persistent disease or morbidity. These changes have made it necessary for the authors to devise more appropriate classifications and, subsequently, several new staging systems were gradually introduced. Recent technological advances, particularly angled endoscopes, have resulted in improved exposure. In the light of all these recent advances, data from our series, and the literature, we suggested a new classification for determining the risk of persistent disease, choosing the appropriate surgical method, and for maintaining uniformity.

            Transnasal endoscopic surgery in juvenile nasopharyngeal angiofibroma.

            A case of angiofibroma limited to the right posterior nasal cavity, nasopharynx and pterygopalatine fossa was operated upon transnasally under endoscopic control. The tumour was completely excised without complications. Endoscopic follow-up for the next two years and contrast computed tomography (CT) excluded any residual tumour or recurrence. The advantages, limitations and possible complications of this approach are discussed. It seems that in limited lesions of angiofibroma, the option of a transnasal endoscopic approach could be cautiously considered by experienced surgeons.

              Endoscopic sinus surgery for benign and malignant nasal and sinus neoplasm.

              Endoscopic sinus surgery has become widely accepted as the standard of treatment for chronic inflammatory diseases of the paranasal sinuses unresponsive to medical treatment. With increased skill with endoscopic surgical technique, advanced technologies such as intraoperative imaging systems, and a better understanding of the complex anatomy of the paranasal sinuses and surrounding vital structures, many otolaryngologists have increasingly applied their expertise in endoscopic sinus surgery to the resection of nasal and sinus neoplasms. The following represents a review of the recent literature on the latest trends regarding endoscopic resection of nasal and paranasal sinus neoplasms. There has been an increasing popularity in the removal of nasal and paranasal sinus neoplasms through an endoscopic approach. In the recent literature, emphasis has been on the endoscopic surgery of benign tumors, especially inverted papilloma and nasopharyngeal angiofibroma. Other benign neoplasms have also been reported, but only in small case reports. There have been a few recent reports supporting endoscopic removal of malignant neoplasms as well. However, the follow-up is too short and study groups too small to make definitive conclusions. In the hand of experienced and skilled surgeons, complete endoscopic removal is attainable in most cases. Especially for the more common benign neoplasms, such as inverted papilloma and early stage angiofibroma. En bloc resection is not necessary to achieve oncologic cure. However, several factors have to be considered before selection of this surgical approach. Large tumor size, intracranial or orbital extension, and extensive frontal or infratemporal fossa involvement are relative, but not absolute limitations.
