Autologous Interposition Grafts for Mucosal Flap Septal Perforation Repair

Background: Nasal septal perforation repair is commonly attempted utilizing bilateral nasal mucosal flaps supported with an interposition graft.Objectives: To compare the failure rates for bilateral flap repairs utilizing four different autologous interposition grafts.Methods: This is a retrospective review of a single surgeon's bilateral flap perforation repairs supported with an autologous interposition graft. Study inclusion over the 18-year review period required at least one examination 1 month after surgery. Repair failure rates were calculated and compared for each graft type, and logistic regression was performed for multivariate analysis.Results: For the 356 study patients, median (range) age was 51 years (14-81) and 63.0% were women. Mean (range) perforation length was 13.9 mm (1-45). Median (range) at last follow-up was 11.2 months (1-192). Graft types used (percentage of patients and failure rate) were temporalis fascia (58.7/4.4), septal cartilage (23.3/7.3), auricular perichondrium (13.8/4.1), and septal bone (4.2/6.7) (p > 0.05).Conclusion: There was no significant difference in bilateral mucosal flap perforation repair failure rate when either a temporalis fascia, septal cartilage, auricular perichondrium, or septal bone interposition graft was used.
