Novel triple‐pedicled mucoperiosteal flaps in reconstruction of neo‐ostium after Draf III frontal sinusotomy for refractory frontal sinusitis

The Draf III frontal sinusotomy has been used extensively in clinical practice. However, stenosis of the frontal neoostium after this procedure is a common risk factor for treatment failure in patients with refractory frontal sinusitis (RFS) because of the large areas of bone exposure.1 Previous studies showed that the mucosal flap grafting techniques could significantly reduce restenosis of the neo-ostia after this procedure.2,3 Based on a systematic review, we report a novel triple-pedicled mucoperiosteal flaps technique in reconstruction and maintaining longterm patency of the frontal neo-ostium after the Draf III procedure.4
