Mucocele de cavidades paranasales / Sinus mucocele

Los mucoceles son quistes expansivos e indolentes de las cavidades paranasales. A pesar de ser lesiones benignas, tienen potencial destructivo local por su expansión crónica y cambios óseos. Su ubicación más frecuente es frontoetmoidal. Se postula que su origen es por alteración de la vía de drenaje de los senos. La clínica es dependiente de su ubicación: los mucoceles frontoetmoidales presentan aumento de volumen, cefalea o proptosis. Las imágenes juegan un rol importante en el diagnóstico, siendo la tomografía computarizada y la resonancia magnética los exámenes que detectan patrones sugerentes de mucoceles. El tratamiento es quirúrgico, donde el abordaje endoscópico ha desplazado al abierto por ser mínimamente invasivo, presentar menos comorbilidades y tener menor tasa de recurrencia.

Mucoceles are expansive and indolent cyst of the paranasal cavities. Despite being benign lesions, they have local destructive potential because of its chronic expansion and bony changes. Its most common location is frontoethmoidal. Alterations in the drainage pathway of sinus is thought to be the origin of mucoceles. The clinical features depend on the location. Frontoethmoidal often presents frontal swelling, headache or proptosis. Imaging plays an important part of diagnosis. Tomography and magnetic resonance have patterns that can suggest the presence of a mucocele. Paranasal sinus mucoceles are primarily treated surgically. The endoscopic surgical management has replaced the open resection because of its minimally invasive treatment, less morbidity and low recurrence rates.

Mucocele: Clinical Characteristics and Outcomes in 46 Operated Patients

Abstract Introduction Paranasal sinus mucocele is a benign, expansive lesion associated with paranasal sinus obstruction. It affectsmostly adults, and ismost common in the frontal and ethmoidal sinuses. Objective To evaluate outcomes in patients undergoing surgical treatment for paranasal sinus mucocele. Methods Retrospective review of medical records of patients treated for paranasal sinus mucocele at the ENT department of a tertiary care hospital between 2005 and 2016. Results Forty-six patients underwent surgical treatment of paranasal sinusmucocele. Themean age was 50.1 years, and 56.5% were male. The most prevalent symptom was pain, and the frontal sinus was most commonly affected. The vast majority of patients (89.1%) underwent endoscopic sinusmarsupialization; 10.9% required combined open and endoscopic access. Seven recurrences occurred. Conclusion Sinus mucocele is an expansive disease that primarily affects the frontal sinus of adult patients. In most cases, endoscopic surgery is an effective treatment modality. (AU)
