Temporoparietal Fascia Graft and Polydioxanone Plate Repair of Nasal Septal Perforation.

Background: 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.

Methods: 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.

Results: 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.

Conclusions: Repair of symptomatic nasal septal perforations using an interposition graft of polydioxanone plate wrapped in temporoparietal fascia demonstrated an overall success rate of 90%.
