Resumen
Los Tumores Nasosinusales originan una frecuencia significativa de las consultas al otorrinolaringólogo, estos dan cuenta de menos del 3% de los cánceres del tracto aerodigestivo superior. Sin embargo, se sabe que los tumores malignos nasosinusales suponen entre el 0,2 y 0,8 del total de los tumores malignos. La incidencia se encuentra entre 1- 1,5 casos por 100.000 personas. Su baja frecuencia y diversidad histológica son un obstáculo para su estudio, clasificación y estatificación, dificultando que los centros donde se atiende esta patología acumulen experiencia sobre los resultados de su tratamiento, por lo que se debe recurrir a estudios multicentricos para establecer criterios epidemiológicos, terapéuticos y pronósticos. El diagnóstico diferencial entre los tumores nasosinusales puede ser difícil, ya que los síntomas pueden ser similares y a veces el hallazgo de una lesión maligna sólo puede ser advertido a la histología. Por ello, resulta crucial realizar un diagnóstico clínico y anatomopatológico, para su tratamiento quirúrgico y coadyuvante.El objetivo del presente estudio es conocer la correlación clínico – quirúrgico e histopatológica de aquellos pacientes que presenten tumores nasosinusales, valorando la evolución de los mismos en el tiempo. Utilizando una metodología tipo Descriptivo – correlacional de Diseño no experimental, longitudinal, retroprospectivo. En el Servicio de Otorrinolaringología del Hospital Regional 2 IESS Dr “Teodoro Maldonado Carbo”, desde junio del 2004 hasta junio del 2011donde se tomaron a 50 pacientes con diagnóstico de tumor nasosinusal. La mayor cantidad de pacientes se ubicó entre 41 – 55 años (28%). El 36% de los pacientes de la muestra estuvo expuesto a agentes, en su mayoría, industriales (80%) con una media de 15 años de exposición.El principal síntoma fue obstrucción nasal (86%) siendo el 70% de los tumores benignos, (42% epiteliales), y el más frecuente el papiloma invertido (30%).Se registró el 36% de recidiva.
Most of the visits to the otorrhinolaryngologist are for treating Nasosinusal Tumors, which less than 3% represents the superior aerodigestive tumors. Nevertheless, it is known that nasosinusal malignant tumors are 0,2% to 0,8% of the total of malignant tumors. The incidences are between 1 to 1,5 cases for each 100.000 persons. Its low histologic frequency and diversity is an obstacle for its classification, estatification and studying, making difficult to the centers where this kind of pathologies are attended, learn and get experience from treatment results. For this reasons, we must access to studies from different centers for establishing epidemiologic and therapeutic criteria, and defining forecasts. The differential diagnoses between the nasosinusal tumors might be difficult since its symptoms may be similar and sometimes the finding of a malignant lesion can only be advice by histology. Because of this, it is crucial to do a clinic and anatomicopathologic diagnose for its surgical and recovery treatment. The objective of this study is to learn the clinic-surgical and histologic correlation of patients with nasosinusal tumor, evaluating their evolution in time. This work will be descriptive-corrlational and the design not experimental, longitudinal, and retrospective.It will be done at the otorrhinolaryngologic service of the Hospital Regional 2 IESS Dr. “Teodoro Maldonado Carbo” , in a period of time between june 2004 to june 2011, and will take as a sample 50 patients with nasosinusal tumor. It is expected to demonstrate the effectiveness of the treatment for tumoral lesions and knowing these results, analyze the advantages and disadvantages of the used techniques.
