RESULTS

Multilayered repair of OAF–ONF using a pedicled intranasal flap combined with an intraoral local flap facilitated excellent closure in both patients. All procedures were completed on an outpatient basis without complications. Postoperative crusting was debrided in the clinic, which resolved any symptoms related to nasal obstruction. At last follow-up for each patient, the fistulae remained closed with well-integrated, healthy tissue (Figure 1, below). In addition, nasal regurgitation was resolved in both patients.
