Abstract
Introduction

Traditional treatment for paranasal sinuses mucoceles recommended total removal through external approaches. Since the 90s, endoscopic marsupialization has been proposed as optimal surgical treatment. We present our experience in the treatment of this pathology.

Material and method

A retrospective review of 72 patients treated for paranasal sinuses mucoceles between 1980 and 2006 in our ENT department was performed. We describe clinical features, surgical approaches employed, and recurrence of disease.

Results

The sample was composed of 72 patients with average follow-up period of 44 months (range, 13–214 months). A total of 81 mucoceles were presented, with 44% affecting the frontal sinus or frontoethmoidal cells, followed in frequency by maxillary sinus mucoceles (35%). Twenty-nine percent of the patients did not present predisposing factors; 31% of patients had a history of nasal polyposis, 35% had undergone previous sinus surgery and 14% suffered previous facial fractures; 48 mucoceles patients were treated endoscopically and 33 were treated with external or combined approaches. Recurrence was found in 7 patients, 2 in the endoscopic surgery group and 5 in the external/combined surgery group.

Conclusions

Endoscopic marsupialization is a safe approach with a low rate of recurrence. The endoscopic approach may be unsuitable for frontal lateral sinus mucoceles or those with significant bone blockage

Resumen
Introducción

El tratamiento tradicional de los mucoceles paranasales consistía en la extirpación mediante abordajes externos. Desde los años noventa se ha propuesto la marsupialización endoscópica como tratamiento de elección. Exponemos nuestra experiencia en el tratamiento de estas lesiones.

Material y método

Se revisaron retrospectivamente 72 historias clínicas de pacientes intervenidos de mucoceles nasosinusales entre 1980 y 2006 en nuestro centro. Se describen las características clínicas, los abordajes quirúrgicos empleados y la aparición de recidivas.

Resultados

La muestra se compone de 72 pacientes con un seguimiento medio de 44 (intervalo, 13–214) meses. Se presentaron un total de 81 mucoceles, de los que el 44% afectaba al seno frontal o las cedillas frontoetmoidales y el 35%, a los senos maxilares. El 29% de los pacientes no presentaban factores predisponentes. El 31% de los pacientes padecían poliposis nasal; el 35%, antecedentes de cirugía nasosinusal, y el 14%, fracturas faciales previas. Se trataron endoscópicamente 48 mucoceles y mediante abordajes externos o mixtos, 33. Apareció recidiva en 7 pacientes, 2 en el grupo de pacientes tratados endoscópicamente y 5 en el grupo de pacientes tratados mediante cirugía abierta o mixta.

Conclusiones

La marsupialización endoscópica es una técnica segura y con bajo índice de recidivas que encuentra como limitación relativa los mucoceles frontales laterales o con tabicación ósea significativa.
