Abstract
Introduction and objectives

Endoscopic sinonasal surgery is the procedure of choice in the treatment of chronic rhinosinusitis and sinonasal polyposis refractory to medical treatment, with high rates of success (76%–97.5%). However, 2.5%–24% of those patients will require revision surgery (RESS). In this study, we present the clinical, anatomical, radiological and histological features of patients receiving RESS in our centre during a 3-year period.

Methods

A retrospective review of clinical, anatomical, radiological and histopathological data of patients receiving revision endoscopic sinonasal surgery between 2012 and 2014 was carried out.

Results

From 299 surgery procedures performed, 27 (9%) were revision surgeries. The mean patient age was 46 years, with a male/female ratio of 1.4/1. The most frequent preoperative and postoperative diagnosis was chronic polypoid rhinosinusitis. The mean time since the previous surgery was 6.1 years, with 11.9 months of mean follow-up since that surgery. Stenotic antrostomy was found during revision in 81.5% of the patients and incomplete anterior ethmoidectomy and persistent uncinate process, in 59.3%. In radiology, 70.4% of patients had persistent anterior ethmoidal cells. Antrostomy or widening of antrostomy was performed in 96.3% of cases and anterior ethmoidectomy or completion of it was performed in 66.7%.

Conclusions

Polyps, stenotic antrostomy and incomplete ethmoidectomy were the most frequent causes of revision surgery, in concordance with the procedures performed. The patients had long periods of time without follow-up between surgeries. Further investigation is necessary to generate measures to reduce the number of revision surgeries.

Resumen
Introducción y objetivos

La cirugía endoscópica nasosinusal es el procedimiento de elección para tratar la rinosinusitis crónica y poliposis nasosinusal refractarias a tratamiento médico, con un alto porcentaje de éxito (76 a 97,5%). Sin embargo, de 2,5 a 24% de los pacientes requieren cirugía de revisión. En este estudio describimos las características clínicas, anatómicas, radiológicas e histológicas de pacientes sometidos a cirugía de revisión en nuestro centro, en un período de 3 años.

Métodos

Revisión retrospectiva de datos clínicos, anatómicos, radiológicos e histopatológicos de pacientes sometidos a revisión entre 2012 y 2014.

Resultados

De 299 procedimientos quirúrgicos realizados, 27 (9%) fueron de revisión. La edad promedio de los pacientes fue 46 años, con una relación hombre:mujer de 1,4:1. El diagnóstico preoperatorio y postoperatorio más frecuente fue rinosinusitis crónica poliposa. El tiempo promedio desde la cirugía previa fue de 6,1 años, con 11,9 meses de seguimiento promedio desde esa cirugía. Un 81,5% de los pacientes presentaba antrostomía estenótica durante la revisión, y un 59,3% etmoidectomía anterior incompleta y proceso unciforme persistente. El 70,4% de los pacientes tenía celdillas etmoidales anteriores persistentes en radiología. Se realizó en un 96,3% de los casos antrostomía o ampliación de esta, y en un 66,7% se realizó o se completó la etmoidectomía anterior.

Conclusiones

Las causas más frecuentes de revisión fueron los pólipos, antrostomía estenótica y etmoidectomía incompleta, concordante con los procedimientos realizados. Los pacientes tuvieron largos períodos sin seguimiento entre cirugías. Es necesario continuar la investigación para generar medidas que reduzcan el número de cirugías de revisión.
