Resumen
objetivo

El del trabajo es estudiar a aquellos pacientes que presentan una ocupación unilateral de fosa nasal, en apariencia polipoidea, y la fosa contralateral normal. Valorando, por un lado, la incidencia real de poliposis inespecíficas y de otros diagnósticos. Y, por otro lado, comparamos los datos que nos ofrece la radiología preoperatoria con los hallazgos quirúrgicos encontrados.

Material y métodos

Hacemos un estudio prospectivo de 23 pacientes recogidos en un periodo de 30 meses en el servicio de ORL del Hospital Dr. Peset de Valencia. Se realiza en todos los pacientes TAC y biopsia preoperatoria, comparándolos posteriormente con los hallazgos quirúrgicos y el diagnóstico anatomopatológico definitivo.

Resultados y conclusiones

Hubo discordancia entre la biopsia preoperatoria y el diagnóstico definitivo en el 26% de los pacientes, siendo la incidencia de poliposis del 52%, papilomas invertidos del 26%, tumores malignos el 13% y otros diagnósticos 8,6%. Hay una buena correlación entre La TAC preoperatoria y los hallazgos quirúrgicos en las poliposis y los papilomas invertidos, pero no en los tumores malignos donde la TAC suele infravalorar las lesiones.

Abstract
Aim

The aim of this paper is to study a group of patients with occupancy of a nasal fossal, apparently by polyps, and being the other side of the nose normal. Evaluating on the one hand the true incidence of unspecific polyposis and, of other diagnosis, and on the other hand to compare the preoperative radiological findings with those seen during surgery.

Material and methods

A prospective study of 23 consecutive patients was carried out over a period of 30 months at the ENT Department of the Dr. Peset Hospital, in Valencia. A CT scan and preoperative biopsy was performed in all cases, the results of these being later compared with the surgical findings and the final histopathologic diagnosis

Results and conclusions

A discrepancy between the preoperative biopsy and final diagnosis was found in 26% of the patients. The incidence of polyposis was 52%, inverted papilloma 26%, malignant tumours 13% and other diagnosis 8.6%. There is a good correlation between preoperative CT scans and surgical findings in those cases of polyposis and inverted papilloma, but not in those of malignant tumours as CT scans often understimated these lesions.
