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%.

Trilayer temporalis fascia interposition graft: A reliable technique for nasal septal perforation repair.

PURPOSE: Nasal septal perforation (NSP) repair is a complex procedure with variable techniques and success rates. In this study we describe NSP repair using a trilayer interposition graft of temporalis fascia and thin polydioxanone (PDS) plate without intranasal flaps and report outcomes in our patient population. MATERIALS AND METHODS: IRB-approved retrospective review of 20 consecutive patients presenting to a tertiary medical center with NSP from September 2018 to December 2020 and who underwent NSP repair via our trilayer temporalis fascia interposition graft. De-identified patient data was obtained from the medical record and stored on an encrypted secure server. Descriptive statistics were examined for each variable. RESULTS: All 20 NSP repairs demonstrated durable repair with complete mucosal coverage at last follow-up (average 7 months). Complete resolution of preoperative symptoms was achieved in 85 % of patients, with partial resolution in the remaining 15 %. Of the 20 perforations 25 % were small (<1 cm), 50 % medium (1-2 cm), and 25 % large (>2 cm). The only surgical complication was a single intranasal synechiae. No graft harvest site complications were noted. CONCLUSION: The application of a trilayer temporalis fascia - PDS plate interposition graft without intranasal flaps is highly effective for repair of NSP.

Risk Factors Associated with Complications in Rhinoplasty Using Polydioxanone Plates.

OBJECTIVE: Polydioxanone (PDS) plates are utilized in septorhinoplasty to reconstruct the nasal septum. Our goal was to analyze factors affecting short- and long-term complications in patients undergoing septorhinoplasty using PDS plates with a particular focus on smoking and diabetes. METHODS: This is a retrospective review of patients undergoing septorhinoplasty with PDS plates analyzing risk factors and outcomes. Early complications included infection, hematoma, extrusion, and septal thickening. Late complications included septal perforation, obstruction, revision, and infection. Complication rate was assessed as a function of demographics, diabetes, smoking, autoimmune disease, cancer, and trauma. Multivariate analyses assessed the contributions of these variables, and Chi-square analyses specifically addressed smoking and diabetes. RESULTS: A total of 119 patients were included. In multivariate analysis, current smoking had a large negative effect on late outcomes (OR 2.00, 95% CI 0.59-6.55), while diabetes did not show any significant difference. Targeted Chi-squared analysis showed a statistically significant effect of current smoking on increased early complications (OR 3.65, 95% CI 1.67-7.63) and a large but not statistically significant increase in long-term complications (OR 4.20, 95% CI 0.72-22.74). In both models, diabetes was not shown to have an effect on early or late complications. CONCLUSION: Current smokers undergoing septorhinoplasty with a PDS plate showed a statistically significant association with early complications and large but not statistically significant association with late complications. Diabetic patients were not found to have an increased complication risk. LEVEL OF EVIDENCE IV: This journal requires that authors assign a level of evidence to each article.

Nasal Septal Perforation Repair with an Inferior Turbinate Flap and Acellular Dermal Matrix.

Nasal septal perforation is an uncommon disorder that can cause disturbance of nasal physiology. The perforations can vary widely in size, location, and symptomatology. Many different closure techniques have been described in the literature; however, no gold standard has been recognized. The choice of surgical technique usually depends on the characteristics of the perforation and surgeon experience. Due to the goal of perforation repair being restoration of normal nasal physiology, techniques with the best outcomes have been those resurfacing the septum with nasal respiratory mucosa. Here we present our novel surgical method for large (> 2 cm) septal perforation closure using a modification of the inferior turbinate flap repair using a polydioxanone plate and the acellular dermal matrix allograft (Alloderm, Allergan Inc.).

Septal perforation repair without intraoperative mucosal closure.

OBJECTIVES/HYPOTHESIS: To report a technique for septal perforation repair that does not rely on intraoperative mucosal closure of the perforation defect. STUDY DESIGN: Case series with prospective and retrospective data collection. METHODS: Nine patients received multilayer interposition grafts and no attempt at intraoperative mucosal closure for repair of septal perforations. Eight patients received multilayer interposition grafts consisting of temporoparietal fascia on one side, polydioxanone plate in the middle, and deep temporal fascia on the other side. One patient received a variant graft consisting of acellular dermal matrix, polydioxanone plate, and full-thickness temporal fascia. Silastic or silicone sheets were placed bilaterally for at least 12 weeks to protect the septum during healing. This technique was applied to a variety of challenging surgical candidates. RESULTS: The eight patients who received interposition grafts with bilateral temporal fascia had complete repair of septal perforation sites. The variant interposition graft had complete loss on the acellular dermal matrix side but good integration of temporal fascia on the contralateral side. CONCLUSIONS: This tension-free technique does not rely on intraoperative mucosal closure of the septal perforation. It has been used to successfully obtain complete repair in a variety of challenging surgical candidates when combined with temporal fascia autografts.
