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\u2010ostium 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.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We reviewed 19 patients who underwent a Draf type II or III procedure with our technique.
