    Abstract:
    Using percutaneous endoscopic surgery, we achieved good results in patients with frontal sinus cyst. The surgical procedure is described and discussed. The endoscopic system consisted of a needle-shaped rigid fiberscope (direct-vision and angle-vision types [30 degrees, 90 degrees]) 1.7 mm in diameter with a light source. A small incision was made at the eyebrow, the sinus was cleaned, and an opposite hole was made through the existing wound. This procedure permitted less invasive surgery under direct view of the surgical field compared with conventional percutaneous transnasal frontal sinus procedures. Postoperative patency of the sinus was also satisfactory. This percutaneous endoscopic procedure was designed for surgical maneuvers in the frontal sinus through a small, 3- to 5-mm incision. This technique is considered effective for the treatment of inflammatory disorders of the frontal sinus caused by positional abnormalities after trauma or recurrence after conservative transnasal surgery.
