Septal Perforation Quality of Life questionnaire (SEPEQOL): validation of a new instrument to assess patients undergoing endoscopic repair of a nasal septal perforation.

PURPOSE: Nasoseptal perforations (NSP) are a clinically heterogeneous group of disorders with a wide range of available treatments. Patient-reported outcome measures (PROMs) can provide valuable insights for assessing clinical and surgical outcomes. This study aims to develop and validate a novel-specific questionnaire for patients with NSP. METHODS: A multi-centre prospective observational study was conducted at two tertiary referral hospitals. "Septal Perforation Quality of Life" (SEPEQOL) was developed by a committee of experts. The psychometric properties, including reproducibility, reliability, validity, and responsiveness, were assessed. RESULTS: The study included 96 symptomatic NSP patients and 30 healthy controls. SEPEQOL internal consistency was satisfactory [Cronbach´s α = 0.7843; 95% confidence interval (CI), 0.702-0.856]. Test-retest reliability was excellent, demonstrated by the absolute intraclass correlation (ICC = 0.974; 95% CI, 0.935-0.989, P-value < 0.001) and Bland-Altman plot (line bias = 1.6 ± 4.57; 95% CI -0.54-3.74, P-value < 0.001). The mean total SEPEQOL score was higher before surgery (25.16 ± 1.65) compared to 6-months after the procedure (13.72 ± 11.39), with a mean difference of 12.19 [standard deviation (SD) 10.76], P-value < 0.001. CONCLUSIONS: SEPEQOL is reliable, consistent, valid, and sensitive to change over time. SEPEQOL assesses the impact of health-related quality of life on NSP and its management in clinical practice. Moreover, it is easy to apply in clinical settings with minimal burden.

Prospective evaluation of nasal septal perforation repair with absorbable plate and temporalis fascia in early adolescent patients.

OBJECTIVES: In the pediatric population, nasal septal perforations (NSP) are rare, and management is not well described. The use of various techniques has been reported in adults, including the use of interposition grafts, however this technique has not been described in the pediatric population. Our hypothesis is that the closure rate using absorbable d-lactide and l-lactide (each 50 %), polymer (PDLLA) plates as interposition grafts with temporalis fascia for NSP repair in the pediatric population will be an effective method compared to previous techniques. METHODS: Chart review was performed on patients who underwent NSP repair before June 2021, results were compared to a prospective evaluation of an interposition plate graft for repair at a tertiary care children's hospital. RESULTS: Fifteen patients via previous techniques and 5 patients via PDLLA and fascia graft were reviewed. Etiology of perforations included 45 % idiopathic, 25 % traumatic, and 15 % iatrogenic. In the previous techniques group, 10 were male, mean (median) age 14.4 years (15.2). Average size of NSP was 12.6 mm ± 6.6 mm (SD). 14/15 (93 %) patients had resolution of symptoms at 10-week follow-up, and 2/15 (13 %) required repeat repair. Five prospective patients were repaired with a PDLLA and fascia interposition graft, 4 were female, mean (median) age 14.6 years (Nassif and Scott, 2021 Feb 1) [14]. Average size of NSP was 11 mm ± 2.2 mm (SD). 100 % had resolution of symptoms at 10-week follow-up, 0 needed repeat surgery. No significant difference was found in size of NSP or in need for repeat procedure (p > 0.05) between the groups. CONCLUSION: Use of absorbable PDLLA interposition grafts with temporalis fascia for NSP repair in the pediatric population is effective at closing and resolving symptoms associated with NSP.

Mucocutaneous Leishmaniasis Rhinology Complications: A Rare Presentation.

OBJECTIVE: This case report presents a unique manifestation of Mucocutaneous Leishmaniasis (MCL) in a 56-year-old woman with chronic nasal symptoms. Initially diagnosed with chronic sinusitis and septal perforation, the patient's history of a childhood sandfly bite and subsequent episodes of Leishmaniasis, revealed after nasal surgery, provided crucial information for accurate diagnosis. METHODS: A retrospective review was conducted on this patient's electronic medical record. RESULTS: The patient's life-long struggle with nasal obstruction, congestion, and a septal perforation initially masked the underlying MCL. Sinus surgery and persistent symptoms further complicated the diagnostic process. Only after postoperative complications, including grainy skin texture extending into the nasal passages, did the patient recall the sandfly bite, prompting reevaluation and diagnosis of MCL. The case highlights the challenges of diagnosing MCL due to its varied presentation and potential mimicry of other chronic nasal conditions. It emphasizes the importance of thorough patient history-taking, especially when symptoms are atypical or persistent. Additionally, the report underscores the potential for unexpected postoperative complications in MCL patients and the need for vigilance in recognizing and assessing them. CONCLUSION: This case contributes to the understanding of MCL's diverse clinical presentation and the importance of early diagnosis and multidisciplinary management for prompt intervention and improved outcomes.

[Closing of nasal septum perforation using adipose stromal vascular fraction: an experimental study]. / Zakrytie perforatsii peregorodki nosa s primeneniem stromal'no-vaskulyarnoi zhirovoi fraktsii: eksperimental'noe issledovanie.

Nasal septal perforation (NSP) is a complex problem in otorhinolaryngology, which leads to impaired nasal breathing and dryness in the nose. This reduces the patient's quality of life and leads to psychological discomfort. The treatment of nasal septum perforation is selected taking into account the clinical manifestations, perforation parameters and general condition of the patient. Currently, a large number of different surgical methods have been described in order to closing the defect of nasal septum. To date, there is no universally accepted method for closing NSP, which stimulates the search and development of new treatment options. OBJECTIVE: Under experimental conditions, to study a new method for closing nasal septum perforation using a collagen scaffold together with adipose stromal vascular fraction containing multipotent mesenchymal stromal cells. MATERIAL AND METHODS: The experiment was carried out on a model of nasal septum perforation in 24 male rabbits divided into four groups, depending on the construct, implanted into the defect zone: the 1st group was the control group - without the introduction of implantation material; the 2nd group - collagen scaffold without adipose stromal vascular fraction; the 3rd group - collagen scaffold with xenogenic adipose stromal vascular fraction; the 4th group - collagen scaffold with allogeneic adipose stromal vascular fraction with further dynamic evaluation of endoscopic control on day 14, after 1 month, 3 months, and 6 months. At month 6, the animals were removed from the experiment, followed by morphological examination in color with hematoxylin and eosin, as well as safranin and methyl green. RESULTS: As a result of the experiment using adipose stromal vascular fraction of allogeneic and xenogenic origin, closing of perforation of the nasal septum of a rabbit for 3 months of dynamic endoscopic control, as well as according to morphological research, was demonstrated. CONCLUSION: Our study showed that the use of adipose stromal vascular fraction containing not only endothelial cells and pericytes, but also multipotent mesenchymal stromal cells in combination with a collagen scaffold closes the perforation of the nasal septum in a rabbit, without increasing the risk of violations of habitual vital activity.

Simultaneous Rhinoplasty and Septal Perforation Repair Using the Bone-Cartilaginous Unit.

BACKGROUND: Various techniques are employed for septal perforation repair but success rates still vary. Numerous mucosal flaps are used for septal perforation closure; however, a scaffold is essential for proper positioning and enhanced mucosal growth. OBJECTIVES: The aim of this study was to assess the effectiveness of utilizing a septal bone/cartilage composite graft (BC unit) to close septal perforations in rhinoplasty patients and evaluate patient satisfaction. METHODS: This case series included patients with septal perforation undergoing rhinoplasty and perforation repair between 2019 and 2023. BC units were used to cover the cartilaginous perforations in all patients. Patients were followed for a minimum of 1 year, assessing surgical results and postoperative satisfaction with the 10-item Standardized Cosmesis and Health Nasal Outcomes Survey (SCHNOS). RESULTS: In this study, 31 patients (22 female, 9 male), with a mean [standard deviation] age of 34.80 [10.31] years (range, 19-59 years), were enrolled. Nine had previousl undergone septoplasty, while four had undergone septorhinoplasty. The preoperative perforation size ranged from 6 to 27 mm (mean, 14.1 mm). At final follow-up, 26 cases (83.8%) achieved complete closure, while 3 had incomplete closures, and 2 experienced reperforation. Analysis revealed a notable mean decrease of 31.93 [26.47] in obstruction domain scores (SCHNOS-O) and a mean decrease of 44.19 [25.37] in cosmesis domain scores (SCHNOS-C). CONCLUSIONS: Septal perforation repair and rhinoplasty can be safely and effectively performed concurrently with BC units for suitable candidates.

"Boot-on-Donut" procedure for anterior and large septal perforation.

BACKGROUND: Surgical closure of large nasoseptal perforation (NSP) is challenging. The use of an extended anterior ethmoidal artery (eAEA) flap to reconstruct NSP may present with difficulties for NSPs which have their upper edge in a high position. METHOD: We propose adding a "donut-shape" flap from surrounding septal tissue to the eAEA flap. Thus, the inverted edges of this flap allow to cover the uppermost aspect of the NSP. A series of 18 patients with complete closure of NSPs was included. CONCLUSION: This novel "Boot-on-Donut" technique consisting of the eAEA flap (Boot) and inverted edges (Donut) is a feasible procedure that allows to reconstruct large NSP located superiorly.

Adaptation and validation of the Spanish version of NOSE-Perf questionnaire for septal perforations.

BACKGROUND AND OBJECTIVE: Septal perforation (SP) cause heterogeneous symptoms depending on the anatomical location, highlighting scabs, nasal obstruction and/or epistaxis. The use of questionnaires to determine the quality of life in different pathologies is increasing in sinonasal pathologies and in patients with SP the NOSE-Perf questionnaire was constructed, currently validated in English. The aim of this study is the translation, cross-cultural adaptation, and validation of the NOSE-Perf questionnaire into Spanish. MATERIAL AND METHODS: Prospective single-centre study of 81 patients (38 with SP and 43 controls), visited in the rhinology section of a tertiary hospital. Adaptation and translation NOSE-Perf into Spanish and validation using the NOSE and NOSE-Perf questionnaire in Spanish. RESULTS: Significant differences were found in the mean NOSE-Perf score and in the mean NOSE score (IC95% = 21.2-26.9; p < 0.001 and IC95% = 53.8-70.5; p < 0.001) between SP group and control group. Pearson's correlation between the two questionnaires NOSE-Perf and NOSE in the SP group was 0.74 (95% CI = 0.56-0.86; p < 0.001). In the control group it was r = 0.85 (95%CI = 0.73-0.91; p < 0.001). Cronbach's alpha coefficient of the NOSE-Perf was 0.95 (IC 95% = 0.93-0.96) for internal consistency. The reliability evaluation was carried out by test-retest, and a strong Pearson correlation was obtained between the questionnaires r = 0.94 (CI95% = 0.85-0.97; p < 0.001) and r = 0.89 (95%CI = 0.77-0.95; p < 0.001). CONCLUSIONS: The Spanish version of the NOSE-Perf is as reliable and valid as the English version, which makes it possible to assess the impact on quality of life that it causes in patients with perforations in the Spanish-speaking population.

[Online survey to determine realistic success rates and trends in surgical septal perforation repair]. / Online-Befragung: realistische Erfolgsquoten und Trends beim operativen Septumperforationsverschluss.

OBJECTIVE: High success rates (SR) for surgical septal perforation repair (SPR) of over 90 % are reported in the literature. We think that realistic SR are significantly lower and wanted to confirm this thesis with the help of a survey among ear, nose, throat ENT specialists from Germany. Surgical trends were also queried. MATERIAL AND METHODS: An anonymous online survey among ENT specialists in Germany was conducted. 356 doctors participated. The collected SR were statistically evaluated, and the operative trends were analysed. It applies a significance level α = 0.05. The SR were collected for 3 different size categories (<1 cm, 1-2 cm, >2 cm). RESULTS: The SR for SPR <1 cm (median 79 %) was higher than that for 1-2 cm (60 %) and >2 cm (40 %). Surgeons estimated SR significantly higher (90 %, 75 %, 50 %; p-value <0.001 each) than non-surgeons (80 %, 50 %, 25 %). Hospital-based physicians (90 %, 70 %, 50 %) reported significantly higher SR than ambulatory physicians (80 %, 50 %, 30 %, p-value <0.001 each). No linear relationship was found between the total number of SPR performed and SR (r <1cm = 0.16, r1-2cm = 0.18, r >2cm = 0.19). Most SPR were performed with the bridge flap technique (73 %), a closed surgical approach (85 %), an interposition graft (74 %) and postoperative splinting (94 %). CONCLUSIONS: The subjective SR suggest that the SR of SPR is lower than described in the literature. This may be due to short follow-up times, small patient populations and a retrospective design of existing studies. The variety of surgical possibilities confirms the complexity of SPR. Optimising the design of future studies could help to collect realistic SR.

Posterior Septal Artery Flap for Endoscopic Repair of Large Nasal Septal Perforation: How I Do It.

Endoscopic repair of large nasal septal perforation (SP) remains a rather challenging procedure. The presented modification of vascularized flap, which is supplied with branches of posterior septal artery, has proven to be convenient and effective in closure of SPs larger than 2 cm. Laryngoscope, 134:3485-3488, 2024.

Validated Symptom Outcomes Following Septal Perforation Repair: Application of the NOSE-Perf Scale.

OBJECTIVE: The Nasal Obstruction Symptom Evaluation (NOSE)-Perf scale was developed and validated to measure symptoms associated with nasal septal perforations. This study reports the application of the NOSE-Perf scale to evaluate symptom change following septal perforation repair. METHODS: Patients with NOSE-Perf evaluations ≥6 months following attempted perforation closure from July 2018 to December 2021 utilizing bilateral nasal mucosal flaps with an interposition graft were eligible for study inclusion. Change in NOSE-Perf scores were noted. Patient demographics, perforation size, and concurrent functional procedures were analyzed for impact on symptom outcomes. RESULTS: One-hundred and seventeen patients met the study criteria. Seventy-nine (67.5%) of the patients were female and the mean (range) age at surgery was 47.3 (14-78) years. Repair failure was noted in 7 (6.0%) patients. Mean (SD) preoperative NOSE-Perf score was 25.3 (95% CI, 23.5-27.1) and postoperative score was 7.9 (95% CI, 6.5-9.3). Minimal clinically important difference (MCID) was estimated and greater than 91% of patients had improvement above this threshold. Patient age, perforation size, or concurrent functional procedures did not impact outcomes. Postoperative scores at short (2-4 months), intermediate (5-8 months), and long-term (≥9 months) time periods showed significant improvement (all p < 0.001) compared to preoperative NOSE-Perf scores. CONCLUSION: Significant reduction in nasal symptoms as measured by the NOSE-Perf scale is noted following bilateral mucosal flap repair. Although the nose does not completely normalize following repair, clinically important improvement was noted in at least 91% of patients. The NOSE-Perf scale is positioned to play a role in the standardization of septal perforation evaluation and outcomes assessment. LEVEL OF EVIDENCE: 4 Laryngoscope, 134:3067-3072, 2024.

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%.

Fascia Lata-Fat Island Graft in Septal Perforation Repair.

Objective: To measure the success of the fascia lata-fat island graft technique in septal perforation repair as measured by nasal endoscopic examination. Background: This study presents the results of using fascia lata-fat island, a different graft technique, for the repair of septal perforations, offering an alternative to this challenging procedure. Methods: This retrospective study assesses nasal septal perforation repair using the fascia lata-fat island graft technique performed by a single surgeon. Inclusion criteria involved completing 12-month follow-ups within a 3-year review period. Success rates were calculated and evaluated alongside patient characteristics. Results: The median (range) age of the 25 patients included in the study was 34 (25-45) years and 72.0% were men. The septal perforation size of all patients was >2 cm and the etiological cause in all of them was previous septal surgery. All patients were followed for 12 months. The perforation was completely closed in 23 of 25 patients (92%). Conclusion: Using a different graft with an open rhinoplasty approach, we achieved a high success rate in patients with large septal perforations, followed for 1 month with nasal stenting and an average follow-up duration of 12 months.

Assessment of a Novel Tool for the Clinical Grading of Nasal Septal Perforation.

BACKGROUND: Nasal septal perforations (NSP) can have a heterogeneous appearance on endoscopic examination with varying degrees of crusting, inflammatory change, and associated septal deviation. The clinical applicability of these findings as contributors to patient symptoms may be enhanced by use of a standardized assessment. METHODS: Video nasal endoscopy recordings were obtained from 40 patients with NSP. Five raters with varied levels of training ranging from a senior resident to an experienced septal perforation surgeon independently reviewed the videos for the following exam findings: crusting, scarring, granulation tissue, septal deviation, and edema. Scoring for each item was reported on a 3-point (0-2) scale, and each reviewer repeated scoring at a 14-day interval. Interrater and intrarater agreement were calculated using Fleiss kappa for each item and the total scores. Additionally, endoscopy scores were correlated with patient-reported NOSE-Perf symptom scores. RESULTS: Interrater agreement for the overall instrument was in the "fair-to-moderate" range with the following interrater agreement for each item: crusting (0.458-0.575), scarring (0.286-0.308), granulation (0.403-0.406), deviation (0.487-0.494), and edema (0.253-0.406). Intrarater agreement was generally "substantial" for individual items as well as the overall instrument (0.688). The NSP endoscopy scores were moderately correlated with NOSE-Perf scores (r = 0.44, p = 0.008). CONCLUSIONS: An endoscopic evaluation of NSP comprising five exam findings has acceptable interrater and intrarater reliability and correlates with patient-reported outcomes. NSP endoscopy may be applied to future clinical studies for characterization of NSP and assessment of treatment outcomes. LEVEL OF EVIDENCE: 3 Laryngoscope, 134:3049-3053, 2024.

Impact of nasal septal perforation on the airflow and air-conditioning characteristics of the nasal cavity.

We investigated (1) how nasal septal perforations (NSPs) modify nasal airflow and air-conditioning characteristics and (2) how the modifications of nasal airflow are influenced by the size and location of the NSP. Computed tomography scans of 14 subjects with NSPs were used to generate nasal cavity models. Virtual repair of NSPs was conducted to examine the sole effect of NSPs on airflow. The computational fluid dynamics technique was used to assess geometric and airflow parameters around the NSPs and in the nasopharynx. The net crossover airflow rate, the increased wall shear stress (WSS) and the surface water-vapor flux on the posterior surface of the NSPs were not correlated with the size of the perforation. After the virtual closure of the NSPs, the levels in relative humidity (RH), air temperature (AT) and nasal resistance did not improve significantly both in the choanae and nasopharynx. A geometric parameter associated with turbinate volume, the surface area-to-volume ratio (SAVR), was shown to be an important factor in the determination of the RH and AT, even in the presence of NSPs. The levels of RH and AT in the choanae and nasopharynx were more influenced by SAVR than the size and location of the NSPs.

Combined endoscopic sinus surgery and endonasal septal perforation repair: Symptom outcomes and perforation closure rates.

KEY POINTS: Combined endoscopic sinus surgery and nasal septal perforation repair is technically feasible. NOSE-Perf is a recently developed patient-reported outcome measure for nasal septal perforation. The decision to perform combined ESS and NSP repair should be made on a case-by-case basis.

Predictors of Success of Endonasal Septal Perforation Repair: A 10-Year Experience.

Background: There is no consensus on optimal repair technique for nasal septal perforations (NSPs). Objective: To measure success rate and evaluate predictors of success for NSP repair. Methods: Medical records of patients who underwent NSP repair from 2010 to 2020 were reviewed. Included patients had at least 60 days of postsurgical follow-up. Surgical technique involves an endonasal approach; subperichondrial dissection with local flap mobilization; and multilayer closure using cartilage interposition graft, fascia graft, and mucoperichondrial flaps. A chi-squared test or Fisher exact test was used for statistical analysis. Results: Eighty-one repairs were performed with a closure rate of 86%. The median patient age was 46 years (range 13-77); 34.6% of perforations were ≥2 cm. Conchal (77.8%), rib (7.4%), or septal (7.4%) cartilage was used as graft material. A complication rate of 8.6% was reported. Perforation size or graft material had no impact on successful closure rate. Of patients with failed repairs, 55% had perioperative complications or conditions associated with poor healing. Conclusion: An endonasal approach for NSP repair showed a high success rate across diverse presentations; however, NSP repair was significantly more likely to be successful in patients without perioperative complications or pre-existing conditions associated with poor wound healing.

Nasal Septal Perforation and Widespread Skin Lesions Caused by Mycobacterium chelonae Infection Mimicking Granulomatosis with Polyangiitis.

Mycobacterium chelonae, a rapidly growing mycobacterium found in the natural environment, is known to cause localized lesions in the skin, soft tissue, and bone through traumatic inoculation, but widespread lesions are uncommon. We herein report an immunocompromised 79-year-old man suspected of having polyangiitis granulomatosis due to weight loss, epistaxis, and nasal crusts with impending septal perforation who was subsequently diagnosed with mucocutaneous and bone disease caused by widespread M. chelonae infection. Given these findings, clinicians should be aware of the tendency to develop unusual widespread lesions in immunocompromised patients, which can present a clinical picture similar to systemic vasculitides, such as granulomatosis with polyangiitis.

The Use of Platelet-Rich Fibrin and Polypropylene Mesh in Repair of Nasal Septal Perforation.

OBJECTIVE: In this study, we aimed to investigate the effectiveness of the use of polypropylene mesh and platelet-rich fibrin (PRF) in nasal septal perforation (NSP) repair. STUDY DESIGN: Prospective experimental study. SETTING: Laboratory. METHODS: Twenty-four adult male New Zealand rabbits were used in our study. In all subjects, a 10 × 10 mm perforation was created in the septum. The subjects were divided into 3 equal groups according to the different methods used in perforation closure. The bilateral mucosal flap was used in the control group, polypropylene mesh + bilateral mucosal flap in the mesh group, and polypropylene mesh + bilateral mucosal flap + PRF in the mesh + PRF group. RESULTS: NSP treatment success rate was found to be significantly higher in the mesh (4/6, 66.7%) and mesh + PRF (6/6, 100%) groups compared to the control group (0/6, 0%). Re-epithelialization score was higher in the mesh + PRF group and the control group compared to the mesh group. While the necrosis, neutrophil, and abscess scores were highest in the mesh group, they were similar to the control group in the mesh + PRF group. CONCLUSIONS: While polypropylene mesh significantly increases the success rate in NSP repair, it causes severe inflammatory responses. However, when polypropylene mesh is combined with PRF, it both increases the rate of perforation closure and significantly reduces the complications associated with the use of mesh.

Factors Affecting the Surgical Outcome in Nasal Septal Perforation Repair.

OBJECTIVE: Nasal septal perforation (NSP) repair is challenging surgery considered in patients with symptomatic NSP intractable to conservative treatments. This study aimed to assess the success rate and identify factors affecting the surgical outcome of NSP by analyzing consecutive series of NSP repairs by a single surgeon. METHODS: We enrolled 84 patients diagnosed with NSP and who underwent surgical repair of NSP by a single surgeon (Y.J.J.) between November 2007 and July 2022. Medical records were retrospectively reviewed regarding variables involving preoperative symptoms, rhinologic history, etiology, surgical techniques, and the outcome of surgery. In addition, features of NSP were objectively evaluated using computed tomography scans. RESULTS: The overall success rate of NSP repair was 64.3% (54 of 84). Nasal obstruction (79.8%), crusting (34.5%), and epistaxis (27.4%) were frequent preoperative symptoms. Iatrogenic injury from previous nasal surgery (70.2%) was the most common cause. The average size of NSP on preoperative CT was 9.53 ± 6.68 mm. Patients with incomplete NSP closure had significantly larger perforations (12.21 ± 7.92 mm) than those with successful closure (8.04 ± 5.41 mm) preoperatively (P = .005). Patients with smoking history (OR = 2.971, 95% CI 1.170-7.548, P = .020) and NSP repair with combined rhinoplasty (OR = 3.811, 95% CI 1.401-10.370, P = .007) were more likely to experience incomplete closure. Patients whose perforations were reinforced with interposition graft were more likely to result in successful repair (OR = 6.752, 95% CI 2.496-18.262, P < .001). The bilaterality of mucosal flap coverage, surgical approach, types of mucosal flap and interposition graft, perforation shape, mucosal thickness around perforation, and distance from the nasal floor were not significantly related to the surgical outcome. CONCLUSIONS: Significant factors affecting the outcome of NSP repair were patient's smoking status, combined rhinoplasty, application of interposition graft, and perforation size.

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.
