ABSTRACT

El espacio parafaríngeo es una región donde puede surgir un amplio espectro de tumores, que son poco frecuentes y comprenden solo el 0,5 al 1,5% de las neoplasias de cabeza y cuello. Generalmente, son hallazgos y suelen presentarse como masas asintomáticas. Incluye neoplasias primarias, extensión directa de regiones adyacentes y enfermedad metastásica. La literatura describe múltiples patologías e histologías que pueden surgir de esta zona, entre ellas, tenemos los tumores fibrosos solitarios, que son un espectro de neoplasias mesenquimatosas fibroblásticas de histogénesis incierta, que generalmente involucran la pleura. Son lesiones muy poco frecuentes y su localización parafaríngea es excepcional, siendo su primer reporte en la literatura en 1993. Se presenta el caso de un tumor fibroso solitario del espacio parafaríngeo evaluado en nuestro centro, con su enfrentamiento diagnóstico, resolución quirúrgica y seguimiento respectivo, con el objetivo de presentar esta patología poco frecuente a nuestros colegas y contribuir al conocimiento médico.


The parapharyngeal space is a region where a wide spectrum of tumors can arise, which are rare and comprise only 0.5% to 1.5% of head and neck neoplasms. They are generally findings and usually present as asymptomatic masses. Includes primary neoplasms, direct extension from adjacent regions, and metastatic disease. The literature describes multiple pathologies and histologies that can arise from this area, among them, we have solitary fibrous tumors, which are a spectrum of fibroblastic mesenchymal neoplasms of uncertain histogenesis, which are generally the pleura. It is a very rare lesion and its parapharyngeal location is exceptional, being its first report in the literature in 1993. We present the case of a solitary fibrous tumor of the parapharyngeal space evaluated in our center, with its diagnos- tic confrontation, surgical resolution and respective follow-up, with the aim of presenting this rare pathology to our colleagues and contributing to medical knowledge.

ABSTRACT

El tumor de Pott es una entidad rara, definida como un absceso subperióstico asociado a osteomielitis del hueso frontal. Suele presentarse como complicación de sinusitis aguda o crónica del seno frontal, y se describe con mayor incidencia en población pediátrica, siendo una complicación grave por su alta morbimortalidad. Se presenta a un paciente pediátrico con tumor de Pott y absceso cerebral posterior a una sinusitis aguda de foco odontogénico, en la que los pilares de tratamiento son drenaje quirúrgico precoz y antibioticoterapia prolongada. Se describe la clínica, manejo médico-quirúrgico y seguimiento posterior, ya que, en ausencia de antecedentes, se debe buscar dirigida- mente enfermedad periodontal y realizar un estudio de inmunodeficiencia primaria.


Pott's tumor is a rare entity, defined as a subperiosteal abscess associated with osteomyelitis of the frontal bone. It usually presents as a complication of acute or chronic sinusitis of the frontal sinus and it is described with a higher incidence in the pediatric population, being a serious complication due to its high morbidity and mortality. We present a pediatric patient with Pott's tumor and brain abscess after acute sinusitis of odontogenic focus, in which the pillars of treatment are an early surgical drainage and prolonged antibiotic therapy. The clinic, medical-surgical management and subsequent follow-up are described, since in the absence of antecedents, periodontal disease should be sought directly and a study of primary immunodeficiency performed.

ABSTRACT

El manejo del sangrado en CEF es fundamental, ya que aumenta la tasa de complicaciones. El principal objetivo del manejo perioperatorio es lograr una buena hemostasia, es por esto que se realizó una revisión de las principales recomendaciones de la literatura internacional, que incluye medidas preoperatorias, intraoperatorias y postoperatorias.


Bleeding is an important factor in FESS since it increases the rate of complications. The main objective of perioperative management is to achieve good hemostasis. This is a review of the main recommendations of the international literature, that includes preoperative, intraoperative and postoperative measures.
