However, this technique is still associated with a high postoperative stenosis rate. The exposure of drilled bone induces osteitis predisposing to scarring and neo-osteogenesis causing ostium restenosis. We developed a novel lateral inferior pedicle flap (LIPF) to cover the exposed bone and prevent restenosis during Draf IIb. We aimed to describe our technique.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>Adult patients requiring a Draf IIb for unilateral recurrent frontal sinus disease were prospectively enrolled. A LIPF technique was systematically performed. Demographics and complications were recorded. The primary outcome measure was neo-ostium patency at 12\u00a0months. In patients with chronic rhinosinusitis (CRS), the clinical control rate was evaluated at 12\u00a0months.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>59 patients underwent the Draf IIb with LIPF technique from 2013 to 2021. 49 patients (20 women\/29 men, median age of 48.0\u00a0years) completed at least 12\u00a0months of follow-up (median 41.0\u00a0months, range 12\u2013100\u00a0months). Indications included recalcitrant CRS (<jats:italic>n<\/jats:italic>\u2009=\u200932), inverted papilloma (<jats:italic>n<\/jats:italic>\u2009=\u20099) and frontal mucocele (<jats:italic>n<\/jats:italic>\u2009=\u20098). Overall, the neo-ostium remained patent at 12\u00a0months in all patients, and the clinical control rate of 32 patients with recalcitrant CRS at 12\u00a0months was 100%.
