This study aims to illustrate the Graz experience. The study is retrospective, 53 patients with orbital complication of sinusitis were examined / confirmed by a University Hospital from 2000 to 2011. Thirty-seven underwent surgery, seven of which experienced a recurrence. The reason could be that the abscess expands and becomes less confined, which makes complete drainage more difficult and thus could lead to recurrence. They found that the recurrence rate increased with the delay to therapy. This study encourages ENT surgeons to follow the Graz concept, and combined or external approaches are still required in selected cases when the infection is located laterally and the abscess is not accessible by endoscopic surgery.
