Surgical repair of septal perforations has been historically cumbersome. Recently described techniques utilizing interposition grafting with polydioxanone (PDS) plates wrapped in a temporoparietal fascia (TPF) graft have reported successful closure in 90% to 100% of cases. Our objective is to expand the investigation into the use of interposition grafts of polydioxanone plates combined with a temporoparietal fascia graft for nasal septal perforation repair. Retrospective review of the medical record was performed for all septal perforation repairs using the TPF-PDS plate interposition graft technique from August 1, 2017 to March 1, 2021 at the University of Iowa. Minimum post-operative follow-up was 1 month. Our series included 31 patients with symptomatic nasal septal perforations. Thirteen patients underwent open while 18 patients underwent endonasal graft placement. The mean perforation size was 1.49 cm2. The mean post-operative follow-up was 11.5 months. Repair of symptomatic nasal septal perforations using an interposition graft of polydioxanone plate wrapped in temporoparietal fascia demonstrated an overall success rate of 90%.
