ABSTRACT

Las lesiones que comprometen la rinofaringe son de difícil diagnóstico debido al complejo acceso a esta región, excepto cuando éstas alcanzan mayor tamaño o cuando presentan síntomas y/o signos secundarios al compromiso de estructuras adyacentes o de diseminación. El propósito de esta investigación fue analizar y describir casos clínicos de pacientes portadores de patología tumoral de la rinofaringe, con la finalidad de aportar nuevos antecedentes en un área en la cual existen pocos estudios publicados, dada su baja incidencia. Se realizó un análisis descriptivo de corte transversal de 10 casos clínicos de pacientes portadores de patologías que comprometían la rinofaringe, evaluados en la unidad de Otoneurología del Instituto de Neurocirugía (1999-2008). De los casos analizados, se observó una mediana de edad de 52,5 años, el tiempo desde la presentación de los síntomas hasta el diagnóstico fue de 8,5 meses. Los tumores de origen epitelial fueron la causa más frecuente, presentándose además tumores de origen óseo y linfoide. El tratamiento fue quirúrgico y asociado a terapia complementaria según necesidad. El número de casos analizados es pequeño, por lo que no es posible sacar conclusiones, sin embargo, dado la clínica inespecífica es fundamental un alto índice de sospecha, e idealmente en el estudio inicial realizar un examen endoscópico en forma rutinaria.


Lesions of rhinopharynx are difficult to diagnose due to the complex access to this área, except when they reach a greater size or when they present symptoms and/or signs secondary to the compression ofadjacent structures or dissemination. The aim of this study was to analyze and to describe clinical cases of patients with rhinopharynx pathologies, with the purpose of giving new antecedents in an area where are few published studies, due to its low incidence. A cross-sectional descriptive study was made of 10 clinical cases of patients with rhinopharynx tumors, which were evaluated in the unit of Otoneurology of the Neurosurgery Institute (1999-2008). The median age was 52.5 years, and the time since the symptoms appear and the diagnosis was made was of 8.5 months. The most frequent causes were tumors of epithelial origin, but also osseous and lymphoid tumors were observed. Treatment was surgical and/or associated to complementary therapy Due to the small number cases analyzed it is not possible to draw conciusions, nevertheless, it is important to have a high índex of suspicion, given the unspecific symptom and signs that they may present, and idealiy in the initial study of these patients it is necessary to perform an endoscopic evaluation.

ABSTRACT

Introducción: El fibroangioma juvenil es un tumor vascular que afecta casi exclusivamente la nasofaringe de adolescentes de sexo masculino. Su manejo es complejo dada su naturaleza vascular y sus frecuentes recurrencias. Objetivo: Mostrar la experiencia de 12 años en fibroangioma juvenil Material y método: Estudio descriptivo retrospectivo de los pacientes que ingresaron con diagnóstico de fibroangioma nasofaríngeo juvenil al Servicio de Otorrinolaringología del Hospital Clínico de la Universidad de Chile entre los años 1996 y 2008, caracterizando al grupo de estudio en cuanto a clínica, diagnóstico, manejo terapéutico, complicaciones y recurrencias. Resultados: Se obtuvo un total de 22 pacientes, todos de sexo masculino, con un promedio de edad de 17,7 años. El síntoma de presentación más frecuente fue la epistaxis a repetición presente en el 81,8 por ciento de los casos. Todos los pacientes se estudiaron con tomografia computarizada y recibieron embolización arterial preoperatoria. La mayoría de los tumores fueron de tipo IIByllC (68,1 por ciento) según Radkowski y la técnica quirúrgica más empleada fue la endoscópica (54,5 por ciento). Hubo sólo una complicación mayor, pero derivada del procedimiento de embolización y no de la cirugía propiamente tal. Se encontró 22,7 por ciento de recurrencias (n =5, todas endoscópicas), con un tiempo libre de enfermedad de 8,2 meses promedio. Discusión y conclusión: Nuestros resultados concuerdan con la gran mayoría de las series publicadas en la literatura. La decisión terapéutica se basa en la determinación del tamaño tumoral y su extensión, prefiriendo inicialmente un abordaje endoscópico por su carácter poco invasivo y por presentar menor sangrado, tiempo quirúrgico y estadía hospitalaria; siempre que el estadio tumoral lo permita. La embolización arterial, independiente de la vía de abordaje, debe ser de rutina.


Introduction: Juvenile nasopharyngeal angiofibroma is a vascular tumor that occurs almost exclusively in the nasopharynx of adolescent males. Its management is complex because of its vascular nature and frequent recurrence. Aim: To review the experience of 12 years in juvenile nasopharyngeal angiofibroma. Material and method: Retrospective study of patients admitted with diagnosis of juvenile nasopharyngeal angiofibroma at the Otorhinolaryngology Department, University of Chile Clinical Hospital, between 1996 and 2008, characterizing the study group in terms of clinical features, diagnosis, treatment, complications and recurrences. Results: We obtained 22 patients, all male, with an average age of 17.7 years. The most common presenting symptom was recurrent epitasis, present in up to 81.8 percent of cases. All patients were studied with computed tomography and received preoperative arterial embolization. Most tumors were type IIB and C (68.1 percent) and the endoscopic surgical technique was predominant. There was only one major complication, but derived from the embolization procedure and not the surgery itself. There was a 22.7 percent recurrence, with disease-free time of 8.2 months on average. Discussion and Conclusion: Our results agree with most of the series published in the literature. The therapeutic decision is based on the determination of tumor size and extension, preferring an initial endoscopic approach, for its minimally invasive nature and because they present less bleeding, surgical time and hospital stay if the tumor stage allows. Arterial embolization, regardless of the surgical approach, should be routine.

ABSTRACT

A not pregnant 4-year-old Jersey cow was presented with the sudden appearance of respiratory noise, nasal discharge and moderate respiratory difficulty. Upon physical examination a snoring-like noise, extended head and neck position, exaggerated abdominal effort, bilateral nasal discharge and left prescapular lymph node enlargement were noted. Sub-occlusion of the initial portion of the respiratory tract was suspected. Radiographic and endoscopic examinations revealed a pedunculate mass on the dorsal aspect of the rhinopharynx, which was removed with endoscopically assisted electrosurgery. Histologic examination revealed a chronic pyogranulomatous inflammation with eosinophilic club-like bodies surrounding small colonies of rod-shaped bacteria. Results of histochemical staining were consistent with Actinobacillus-like bacteria and a diagnosis of respiratory actinobacillosis was reached. Surgery and antibiotic therapy were resolutive, as demonstated by an endoscopic check at the second month after surgery, even without the association of the traditional iodine cure, which is regarded as the treatment of choice for actinobacillosis.
