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.
