The Draf III septal flap technique: A preliminary report

AimThe most prevalent complication of Draf III surgery is recurrence of frontal recess stenosis. The aim of this study is to introduce a method to prevent closure of the recess.Type of the Study and SettingThis is a retrospective study that was conducted in Ear, Nose and Throat Referral Center, Amir'Alam Hospital, Tehran.Methods and MaterialsWe introduced a new technique for reconstructing frontal recess mucosa and prevention of restenosis following Draf III operation; we covered the posterior wall of the common recess with a vascular mucosal flap from nasal septum.ResultsDuring a 6-month period we used septal flaps based on anterior ethmoidal artery on four patients who had undergone endoscopic Draf III operation. During a 3-month follow-up period, frontal recess stenosis did recur in any of the patients.ConclusionApplying a precise and astute surgical method along with reconstructing common recess mucosa will improve the outcomes of endoscopic frontal sinus drill-out. We strongly recommend application of septal mucosal flap based on the anterior ethmoidal artery during Draf III operation to decrease the incidence of scar and recurrence of common frontal recess stenosis.
