Abstract

Background: Although the efficacy of Draf type II and III procedures for frontal sinus diseases is well recognized, a certain amount of postoperative stenosis of the frontal neo-ostium occurs. Exposed bone induces inflammation and leads to osteoneogenesis. To prevent stenosis, we developed a surgical technique designed to minimize bone exposure while maximizing the frontal neo-ostium area created with Draf type II and III procedures. We fully exposed the lacrimal sac and used a superior lateral anterior pedicle flap to cover the exposed bone during the Draf procedure. We aimed to describe our technique. Methods: We reviewed 19 patients who underwent a Draf type II or III procedure with our technique. Endoscopic views from the follow-ups and complications were evaluated. Results: Overall, the neo-ostium remained patent in all patients. No complications, such as synechiae or orbital injury, were seen in any of the patients. Conclusion: Draf type II and III procedures with lacrimal sac exposure and a superior lateral anterior pedicle flap are convenient and seem to be effective. However, further studies with larger numbers of patients are needed to verify our technique.
