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.

Research and invention of sinus cavity flushing drainage tube and clinical application in the minimally invasive treatment of sinus cavity pressure ulcer / 中华危重病急救医学

Objective To develop a washing tube for minimally invasive treatment of sinus cavity pressure ulcer, and to observe its clinical effect. Methods Using transparent non-toxic PU plastic to make sinus cavity flushing and drainage tube, and with rounded hemispherical blunt head for the entry of the sinus, the perforated tube in the sinus cavity was designed with perforated holes (3 rows, 5 for each row); the end of the tube is blocked with heparin cap. The invented sinus cavity flushing tube was used for clinical observation and its use effect was observed. When used, the sinus cavity flushing drainage tube must be placed in the deepest antrum. The wounds were covered with PU sponge. By the active aspiration drainage of the negative pressure with sterile isotonic flushing fluid, bacteria, liquefied necrotic tissue, purulent secretion, internal and external toxins produced by bacteria, and the harmful material such as exudate of inflammatory medium in the sinus cavity was thoroughly removed. Results When treating sinus cavity and mixed pressure ulcer, minimally invasive treatment using the developed sinus cavity flushing drainage tube for irrigation and negative pressure drainage can significantly reduce patients' iatrogenic trauma, observably reduce the pain of the patients, shorten the treatment cycle, improve the cure rate of sinus pressure ulcers, and achieve good clinical effect. The sinus cavity flushing drainage tube has no damage to soft tissue, with simple operation and easy tolerance of patients. It is low price and using disposable materials, which can avoid cross-infection; It can be used to treat oxygen negative pressure in sinus cavity, and it has therapeutic effect on the sinus cavity pressure sore infected by anaerobic bacteria. It can be made into different specifications, different models, and widely used in different professional fields. Conclusion The sinus cavity flushing drainage tube combined with negative pressure treatment is a new technique of mild and undamaged cleansing wound, which makes up for the deficiency of flap surgery, and it is a very ideal method for minimally invasive treatment for sinus and cavity pressure ulcers.
