레이저를 이용한 비내 수술 후 양측 사골동에 발생한 점액낭종 1례

Paranasal sinus mucoceles are benign diseases that are formed by chronic inflammation, nasal polyps, adhesion after surgery, tumors, trauma etc. that obstruct the paranasal sinus orifices or lesser salivary glands orifices which cause mucous flow to be pooled, causing expansion, focal bone destruction and increase in pressure in the surrounding tissue. Treatment is done by radical therapy by total removal of the polyp or by conservative care by post-op marsupialization and orifice maintenance, the latter being performed more often by endoscopy. Recently, surgery using lasers are being performed more often because the laser does not touch the excision site, so the operative field of view is not blocked by the surgical equipment, and bleeding control is possible with the removal of the tissue. However, lasers have the side effect of damaging the tissue with heat, forming scars around the surgery site. We have recently experienced one case of bilateral ethmoid sinus mucoceles that were formed after intranasal surgery using laser in private practices. Endoscopic sinus surgery was performed under local anesthesia for mucocele marsupialization. (J Clinical Otolaryngol 2005;16:320-322)
