PERCUTANEOUS ENDOSCOPIC SINUS SURGERY FOR FRONTAL SINUSITIS OR A CYST

Using percutaneous endoscopic surgery, we achieved good results in pat ients with frontal sinus cyst. The surgical procedure is described and discussed. The endoscopic system consisted of a needle-shaped rigid f iberscope (direct-vision and angle-vision types [30 degrees, 90 degree s]) 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 t hrough the existing wound. This procedure permitted less invasive surg ery under direct view of the surgical field compared with conventional percutaneous transnasal frontal sinus procedures. Postoperative paten cy of the sinus was also satisfactory. This percutaneous endoscopic pr ocedure was designed for surgical maneuvers in the frontal sinus throu gh a small, 3- to 5-mm incision. This technique is considered effectiv e for the treatment of inflammatory disorders of the frontal sinus cau sed by positional abnormalities after trauma or recurrence after conse rvative transnasal surgery.
