비내시경과 천공술로 치료한 전두 점액낭종 1예

The frontal sinus mucocele is the most common mucocele of the paranasal sinus. The paranasal mucocele is a chronic expansion of lesion that contains inspissated mucus, which occurs when there is an obstruction of the sinus ostium. Endoscopic sinus marsupialization, non-invasive and the most successful method, has been perfromed in many cases of the frontal sinus mucocele. However. this technique has its limitation in narrowing front-al recess and lateralizing mucocele in frontal sinus as well as some disadvantages. The surgery can cause mucocele remnants and early frontal ostium obstruction due to the tissue granulation. A 40 year old male patient with lateralizing frontal sinus mucocele which is extended to the intracranial cavity, was presented. The endoscopic sinus marsupialization can be performed on this patient. Alternatively, the external approach can be done by using a silicon drainage insertion and a trephination.
