Prevalence of chronic rhinosinusitis without/with nasal polyps according to severity in Spain.

BACKGROUND: The worldwide prevalence range of chronic rhinosinusitis (CRS) is 5-12%; from this, 20 % have nasal polyps. Due to the little epidemiological data about CRS in the Spanish population, this study analyses the prevalence and severity of CRS with (CRSwNP) or without (CRSsNP) nasal polyps, and their connection with other coexisting type 2 inflammatory diseases in Spain. METHODOLOGY: This is a retrospective, large-scale, nationwide, epidemiological study based on the electronic medical records from the BIG-PAC® database. Patients diagnosed of CRSsNP and CRSwNP were identified using specific disease codes. The severe form of the disease was defined as patients who received at least a long course of antibiotics in CRSsNP or ≥2 short courses of systemic corticosteroids in CRSwNP in ≤12 months during the last 2 years, and/or had previous sinus surgery. Physician diagnosed prevalence, sociodemographic and clinical characteristics, and disease severity were assessed. RESULTS: Out of a cohort of 1,012,257 patients (≤18 years old), 42,863 and 7,550 patients with diagnosed CRSsNP and CRSwNP, respectively, were analysed. The overall prevalence of diagnosed CRS was 5.1%, being 4.3% and 0.8% for CRSsNP and CRSwNP, respectively. Patients with CRSwNP and severe forms of the disease were older and had higher levels of type 2 inflammatory biomarkers than CRSsNP patients and non-severe disease. CONCLUSIONS: Although CRSsNP was more prevalent than CRSwNP, the severe forms of CRS were more frequent in patients with CRSwNP. In addition, CRSwNP patients had a higher incidence of coexisting type 2 inflammatory diseases.

Low levels of miR-143-3p are associated with severe chronic rhinosinusitis with nasal polyps.

microRNAs (miRNAs) are small, single-stranded, non-coding RNA molecules that regulate post-transcriptional gene expression. Accumulating evidence suggests their involvement in regulating various biological and pathological processes, including inflammation. Studies have revealed distinct expression patterns of miRNAs in Chronic Rhinosinusitis with (CRSwNP) and without (CRSsNP) nasal polyps (1). Specifically, miR-155 and miR-21 have been observed to be upregulated in CRSwNP, increasing and attenuating the expression of pro-inflammatory cytokines, respectively (2,3). Conversely, the downregulation of miR-34, miR-449, and members of the miR-200 family has been associated with impaired ciliogenesis and the regulation of epithelial-mesenchymal transition, respectively (4,5). Nonetheless, the direct role of miRNAs in CRSwNP is still being investigated.

Effect of Different Therapeutic Strategies on Olfactory Outcomes in Patients With Chronic Rhinosinusitis With Nasal Polyps: A Systematic Review.

INTRODUCTION: Olfactory impairment is one of the cardinal symptoms of chronic rhinosinusitis with nasal polyps (CRSwNP). However, the effect of currently available therapeutic options on the recovery of the sense of smell is not well defined. The aim of this systematic review was to compile evidence on the impact of medical, surgical, and biological treatment on olfactory outcomes in patients with CRSwNP. METHODS: This review was conducted by 2 reviewers according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. The quality of evidence of all the studies included in the qualitative synthesis was evaluated using the Critical Appraisal Skills Programme (CASP). RESULTS: Forty-four studies were included in the qualitative synthesis. These assessed sinonasal surgery (n=23), biologics (n=15), and conventional medical treatment (n=6). The methodological quality was moderate-to-high in most. Overall, significant improvements in the sense of smell were detected with all the interventions analyzed and measured using an objective tool, a subjective tool, or both. However, most studies used different outcome measures, thus hindering comparisons between interventions, and data on clinically relevant changes were missing. CONCLUSION: Oral corticosteroids, biologics, and sinonasal surgery improve the olfactory impairment associated with CRSwNP. However, the heterogeneous nature of existing studies does not allow accurate comparisons.

Consensus criteria for chronic rhinosinusitis disease control: an international Delphi Study.

BACKGROUND: Chronic rhinosinusitis (CRS) disease control is a global metric of disease status for CRS. While there is broad acceptance that it is an important treatment goal, there has been inconsistency in the criteria used to define CRS control. The objective of this study was to identify and develop consensus around essential criteria for assessment of CRS disease control. METHODS: Modified Delphi methodology consisting of three rounds to review a list of 24 possible CRS control criteria developed by a 12-person steering committee. The core authorship of the multidisciplinary EPOS 2020 guidelines was invited to participate. RESULTS: Thirty-two individuals accepted the invitation to participate and there was no dropout of participants throughout the entire study (3 rounds). Consensus essential criteria for assessment of CRS control were: overall symptom severity, need for CRS-related systemic corticosteroids in the prior 6 months, severity of nasal obstruction, and patient-reported CRS control. Near-consensus items were: nasal endoscopy findings, severity of smell loss, overall quality of life, impairment of normal activities and severity of nasal discharge. Participants’ comments provided insights into caveats of, and disagreements related to, near-consensus items. CONCLUSIONS: Overall symptom severity, use of CRS-related systemic corticosteroids, severity of nasal obstruction, and patient-reported CRS control are widely agreed upon essential criteria for assessment of CRS disease control. Consideration of near-consensus items to assess CRS control should be implemented with their intrinsic caveats in mind. These identified consensus CRS control criteria, together with evidence-based support, will provide a foundation upon which CRS control criteria with wide-spread acceptance can be developed.

Validation of Visual Analogue Scale for loss of smell as a quick test in chronic rhinosinusitis with nasal polyps.

BACKGROUND AND OBJECTIVE: Diagnostic criteria of chronic rhinosinusitis with nasal polyps (CRSwNP) include, among others, olfactory dysfunction (OD). We hypothesize that patients suffering with CRSwNP are good at self-assessing their sense of smell through visual analogue scale (VAS) compared to smell tests. METHODS: A controlled cross-sectional study was planned. Adults diagnosed with severe CRSwNP waiting for endoscopic sinus surgery were included. A cohort of healthy controls was also studied. All participants performed Barcelona smell test (BAST-24), sinonasal outcomes test 22 (SNOT-22), and VAS for loss of smell. CRSwNP underwent blood test (eosinophils count, total serum IgE), CT scan (Lund-Mackay Score), and nasal endoscopy. RESULTS: 138 severe CRSwNP and 40 controls subjects were included. The BAST-24 identification score was strongly correlated with the VAS score in the CRSwNP group (rho=-0.79, p<0.001) but not in the control group (rho=-0.14; p=0.39), this difference between groups being statistically significant (p<0.001). A significant correlation of SNOT-22 item 21 (loss of smell) was also found with BAST-24 identification (rho=-0.65, p<0.001), this difference being statistically significant (Z=-2.43; p=0.015). In the ROC curve, the area under the curve (AUC) was 0.85 with 72.5% sensitivity and 93.1% specificity. CONCLUSION: This study demonstrates a potential role of the VAS score for the screening of OD in severe CRSwNP in daily clinical practice.

Septoplasty and/or inferior turbinoplasty produce significant improvements of the sense of smell.

BACKGROUND: Patients with septal deviation and/or turbinal hypertrophy may experience olfactory disfunction (OD). The aim of this study was to analyse the effect of septoplasty and/or turbinoplasty on both lateralized and bilateral olfactory function. METHODOLOGY: Prospective study of 47 patients with nasal obstruction secondary to septal deviation and/or turbinal hypertrophy and 20 healthy controls. The Barcelona Olfactory test (BOT-8), a new supraliminal orthonasal subjective olfactometry, was applied 3 times in a row (in each nostril separately and in both simultaneously). The 8 items were applied randomly to minimize the possible risk of learning. The test has not established the minimal clinically important difference (MCID). Anterior rhinomanometry and acoustic rhinometry were performed. All participants self-assessed smell loss and nasal obstruction using a visual analogue scale (VAS) and completed questionnaires for nasal obstruction (Nasal Obstruction Symptom Evaluation, NOSE) and for quality of life (QoL), using disease-specific (SinoNasal Outcome Test-22, SNOT-22) and generic (Short Form-12 Health Survey, SF-12) questionnaires. Nasal measurements and questionnaires were performed preoperatively and 12 months after surgery. RESULTS: Before surgery, patients reported worse VAS on smell loss and on nasal obstruction compared to controls. Patients scored lower BOT-8 than controls. Lateralized preoperative olfactory function showed that all BOT-8 characteristics were lower at the narrow side than the wider one. Smell function and QoL improved significantly one year after surgery. CONCLUSIONS: Nasal septal deviation and turbinal hypertrophy lead to an olfactory impairment on the obstructed nostril. Nasal surgery provides a positive outcome on olfactory function, as well as on subjective and objective outcomes.

Spanish Consensus on the Management of Chronic Rhinosinusitis With Nasal Polyps (POLIposis NAsal/POLINA 2.0).

Chronic rhinosinusitis with nasal polyps (CRSwNP) is a highly prevalent and burdensome disease for both individuals and health systems. Its management involves many specialties, including otorhinolaryngology, allergology, pulmonology, primary care, pharmacy, and pediatrics. A multidisciplinary approach and the participation of the patient in decision-making are essential, both for diagnosis and for therapy. The authors of the consensus aim to translate current knowledge into an easy-to-read practical guide and emphasize those aspects requiring further discussion or with unmet needs owing to the lack of appropriate scientific evidence. An iterative approach for the development of an evidence-based systematic review with recommendations was followed using a standard quality assessment approach (Scottish Intercollegiate Guidelines Network [SIGN] and National Institute for Health and Care Excellence [NICE]). The guideline was critically evaluated using the Appraisal of Guidelines for Research and Evaluation (AGREE II) and Recommendation Excellence (AGREE REX) instruments. Consequently, POLINA has been considered a high-quality guideline by an independent agency. The POLINA consensus provides new definitions of control, therapeutic management (including surgery and evaluation of severity), indications for use of biologics, and response. Finally, this guideline focuses on unmet research needs in CRSwNP.

The EUFOREA pocket guide for chronic rhinosinusitis.

Chronic rhinosinusitis (CRS) is known to affect around 5 % of the total population, with major impact on the quality of life of those severely affected (1). Despite a substantial burden on individuals, society and health economies, CRS often remains underdiagnosed, under-estimated and under-treated (2). International guidelines like the European Position Paper on Rhinosinusitis and Nasal Polyps (EPOS) (3) and the International Consensus statement on Allergy and Rhinology: Rhinosinusitis 2021 (ICAR) (4) offer physicians insight into the recommended treatment options for CRS, with an overview of effective strategies and guidance of diagnosis and care throughout the disease journey of CRS.

Improvement in Olfaction in Patients With CRSwNP and Severe Asthma Taking Anti-IgE and Anti-IL-5 Biologics: A Real-Life Study.

BACKGROUND AND OBJECTIVES: Chronic rhinosinusitis with nasal polyps (CRSwNP), which is characterized by partial loss of smell (hyposmia) or total loss of smell (anosmia), is commonly associated with asthma and/or nonsteroidal anti-inflammatory drug-exacerbated respiratory disease (N-ERD). CRSwNP worsens disease severity and quality of life. The objective of this real-world study was to determine whether biological treatments prescribed for severe asthma can improve olfaction in patients with CRSwNP. A further objective was to compare the improvement in in olfaction in N-ERD and non-N-ERD subgroups. METHODS: We performed a multicenter, noninterventional, retrospective, observational study of 206 patients with severe asthma and CRSwNP undergoing biological treatment (omalizumab, mepolizumab, benralizumab, or reslizumab). RESULTS: Olfaction improved after treatment with all 4 monoclonal antibodies (omalizumab [35.8%], mepolizumab [35.4%], reslizumab [35.7%], and benralizumab [39.1%]), with no differences between the groups. Olfaction was more likely to improve in patients with atopy, more frequent use of short-course systemic corticosteroids, and larger polyp size. The proportion of patients whose olfaction improved was similar between the N-ERD (37%) and non-N-ERD (35.7%) groups. CONCLUSIONS: This is the first real-world study to compare improvement in olfaction among patients undergoing long-term treatment with omalizumab, mepolizumab, reslizumab, or benralizumab for severe asthma and associated CRSwNP. Approximately 4 out of 10 patients reported a subjective improvement in olfaction (with nonsignificant differences between biologic drugs). No differences were found for improved olfaction between the N-ERD and non-N-ERD groups.

Sinonasal mucosal melanomas: defining profiles for better survival outcomes.

BACKGROUND: Sinonasal mucosal melanoma is an aggressive malignancy with a 5-year survival rate ranging from 20% to 39%. Despite the evolving surgical and radiotherapy techniques, and introduction of immune-checkpoint inhibitor therapy, overall survival rates remain poor. METHODOLOGY: A retrospective cohort study was conducted at the Hospital Clinic de Barcelona and the Hospital de la Santa Creu i Sant Pau between 1984 and 2020; primary outcome measures were 3 and 5-year melanoma-specific survival (MSS). Kaplan-Meier survival analysis and Cox proportional hazards model were performed to identify predictors of survival. RESULTS: Fifty patients were included, the mean age was 70.4, MSS at 3 and 5 years was 51.2%, and 29.5%, respectively. The median follow-up was 39.6 months during which 46% presented locoregional recurrence and 36%, metastasis. The univariate and multivariate analyses found as survival predictors the N category, the treatment received, the surgical margins and the mitotic index. CONCLUSIONS: We found an overall 5-year MSS of 29.5%. Those patients with intention-to-cure (stages III and IVa) treated by surgery that were N0 at diagnosis, with < 10 mitoses per HPF showed a 5-year MSS rate of 74.1%. More studies will be needed to adequately define the patients' profiles that will benefit from a better survival outcome.

Twelve-year long-term postoperative outcomes in patients with chronic rhinosinusitis with nasal polyps.

BACKGROUND: Evidence regarding long-term postoperative follow-up of chronic rhinosinusitis with nasal polyps (CRSwNP) patients is scarce in the literature. The objective of the present study was to report long-term 12-year postoperative outcomes for CRSwNP patients. METHODS: CRSwNP patients were prospectively followed after endoscopic sinus surgery. Sinonasal symptoms, nasal polyp score (NPS), Barcelona Smell Test 24 (BAST-24), Lund-Mackay Score (LMS), and Medical Outcome Study Short Form-36 (SF-36) questionnaire were assessed before and 12 years after surgery. RESULTS: At long-term follow-up (median, 12 years), a strong improvement was noted for all patients (N=76) in nasal symptoms score, NPS, BAST-24, and LMS scores compared with baseline. No long-term improvement in SF-36 was found. CONCLUSION: Patients with CRSwNP have a long-term 12-year postoperative improvement in nasal symptoms, polyp size, computed tomography, and olfaction.

Functional Examination of the Upper and Lower Airways in Asthma and Respiratory Allergic Diseases: Considerations in the Post-SARS-CoV-2 Era.

Airway examination procedures can potentially transmit infectious diseases to patients and to the health care professionals who perform them via various mechanisms. The COVID-19 pandemic has halted most of the activity of the clinics and laboratories involved in assessment of lung and nasal function, and clear recommendations in this regard have been made. Today, we still do not know for sure what its consequences will be in the short or long term, since important gaps remain in our knowledge of aspects as fundamental as virus transmission mechanisms, pathophysiology, immune response, and diagnosis. In this review, we study the examination techniques used to assess patients with respiratory allergy, asthma, and associated diseases during this period and highlight their possible advantages and disadvantages. Therefore, we focus on exploring the entire upper and lower airways, from the perspective of the safety of both health professionals and patients and their specific characteristics. We also analyze the intrinsic value of these interventions in terms of diagnosis and patient management. The changing situation of COVID-19 may mean that some of the assertions presented in this review will have to be modified in the future. While we seek to ensure a consistently broad approach, some differences in operational details may apply owing to local regulations.

Endoscopic endonasal surgery to treat intrinsic brainstem lesions: correlation between anatomy and surgery.

OBJECTIVE: The endoscopic endonasal approach (EEA) has been proposed as an alternative in the surgical removal of ventral brainstem lesions. However, the feasibility and limitations of this approach to treat such pathologies are still poorly understood. This study aimed to report our experience in five consecutive cases of intrinsic brainstem lesions that were managed via an EEA, as well as the specific anatomy of each case. METHODS: All patients were treated in a single center by a multidisciplinary surgical team between 2015 and 2019. Before surgery, a dedicated anatomical analysis of the brainstem safe entry zone was performed, and proper surgical planning was carried out. Neurophysiological monitoring was used in all cases. Anatomical dissections were performed in three human cadaveric heads using 0° and 30° endoscopes, and specific 3D reconstructions were executed using Amira 3D software. RESULTS: All lesions were located at the level of the ventral brainstem. Specifically, one mesencephalic cavernoma, two pontine ca- vernomas, one pontine gliomas, and one medullary diffuse midline glioma were reported. Cerebrospinal fluid leak was the major complication that occurred in one case (medullary diffuse midline glioma). From an anatomical standpoint, three main safe entry zones were used, namely the anterior mesencephalic zone (AMZ), the peritrigeminal zone (PTZ, used in two cases), and the olivar zone (OZ). Reviewing the literature, 17 cases of various brainstem lesions treated using an EEA were found. CONCLUSIONS: To our knowledge, this was the first preliminary clinical series of intrinsic brainstem lesions treated via an EEA presented in the literature. The EEA can be considered a valid surgical alternative to traditional transcranial approaches to treat selected intra-axial brainstem lesions located at the level of the ventral brainstem. To achieve good results, surgery must involve comprehensive anatomical knowledge, meticulous preoperative surgical planning, and intraoperative neurophysiological moni- toring.

Direct Costs of Acute Rhinosinusitis in Spain: A Prospective and Observational Study (PROSINUS).

BACKGROUND AND OBJECTIVES: The incidence of acute rhinosinusitis (ARS) is high throughout the world. Although diagnosis is clinical and disease course is mostly self-limiting, diagnostic tools and medications are overused by physicians, thus increasing the direct medical costs of the disease. Objective: The aim of the PROSINUS study was to quantify the direct medical costs of management of ARS in Spain. METHODS: We performed a prospective observational study of 1610 patients with a clinical diagnosis of nonbacterial, uncomplicated ARS. According to the duration of symptoms by the European Position Paper on Rhinosinusitis and Nasal Polyps, patients were classified as having viral or postviral ARS with different levels of severity. Direct medical costs were calculated based on medical visits, use of diagnostic tools, and medications prescribed. RESULTS: Overall, the mean (SD) direct medical costs per episode were €322.3 (301.2) vs €441.1 (344.3) for viral and postviral ARS episodes, respectively (P<.001). When viral and postviral disease were compared, the medical costs per episode were €245.0 (265.4) vs €328.4 (301.9) for medical visits (P<.001), €38.1 (64.0) vs €61.9 (78.8) for diagnostic tools (P<.001), and €39.2 (25.9) vs €50.8 (25.3) for medications prescribed (P<.001). CONCLUSION: The direct medical costs of postviral ARS episodes were higher than those of viral episodes (common cold). Uncomplicated nonbacterial ARS represents an important socioeconomic burden owing to the excessive number of medical visits, use of diagnostic tools, and medications prescribed.

Smell and Taste Dysfunction in COVID-19 Is Associated With Younger Age in Ambulatory Settings: A Multicenter Cross-Sectional Study.

BACKGROUND AND OBJECTIVE: Since the initial anecdotal reports of coronavirus disease 2019 (COVID-19) from China, a growing number of studies have reported on smell and/or taste dysfunction (STD). Objective: The aim of our study was to investigate the frequency and severity of STD in COVID-19 patients and to evaluate the association with demographic characteristics, hospital admission, symptoms, comorbidities, and blood biomarkers. METHODS: We performed a multicenter cross-sectional study on patients who were positive for SARS-CoV-2 (n=846) and controls (n=143) from 15 Spanish hospitals. Data on STD were collected prospectively using an in-person survey. The severity of STD was categorized using a visual analog scale. We analyzed time to onset, recovery rate, time to recovery, hospital admission, pneumonia, comorbidities, smoking, and symptoms. RESULTS: STD was at least 2-fold more common in COVID-19-positive patients than in controls. COVID-19-positive hospitalized patients were older, with a lower frequency of STD, and recovered earlier than outpatients. Analysis stratified by severity of STD showed that more than half of COVID-19 patients presented severe loss of smell (53.7%) or taste (52.2%); both senses were impaired in >90%. In the multivariate analysis, older age (>60 years), being hospitalized, and increased C-reactive protein were associated with a better sense of smell and/or taste. COVID-19-positive patients reported improvement in smell (45.6%) and taste (46.1%) at the time of the survey; in 90.6% this was within 2 weeks of infection. CONCLUSION: STD is a common symptom in COVID-19 and presents mainly in young and nonhospitalized patients. More studies are needed to evaluate follow-up of chemosensory impairment.

European Position Paper on Rhinosinusitis and Nasal Polyps 2020.

The European Position Paper on Rhinosinusitis and Nasal Polyps 2020 is the update of similar evidence based position papers published in 2005 and 2007 and 2012. The core objective of the EPOS2020 guideline is to provide revised, up-to-date and clear evidence-based recommendations and integrated care pathways in ARS and CRS. EPOS2020 provides an update on the literature published and studies undertaken in the eight years since the EPOS2012 position paper was published and addresses areas not extensively covered in EPOS2012 such as paediatric CRS and sinus surgery. EPOS2020 also involves new stakeholders, including pharmacists and patients, and addresses new target users who have become more involved in the management and treatment of rhinosinusitis since the publication of the last EPOS document, including pharmacists, nurses, specialised care givers and indeed patients themselves, who employ increasing self-management of their condition using over the counter treatments. The document provides suggestions for future research in this area and offers updated guidance for definitions and outcome measurements in research in different settings. EPOS2020 contains chapters on definitions and classification where we have defined a large number of terms and indicated preferred terms. A new classification of CRS into primary and secondary CRS and further division into localized and diffuse disease, based on anatomic distribution is proposed. There are extensive chapters on epidemiology and predisposing factors, inflammatory mechanisms, (differential) diagnosis of facial pain, allergic rhinitis, genetics, cystic fibrosis, aspirin exacerbated respiratory disease, immunodeficiencies, allergic fungal rhinosinusitis and the relationship between upper and lower airways. The chapters on paediatric acute and chronic rhinosinusitis are totally rewritten. All available evidence for the management of acute rhinosinusitis and chronic rhinosinusitis with or without nasal polyps in adults and children is systematically reviewed and integrated care pathways based on the evidence are proposed. Despite considerable increases in the amount of quality publications in recent years, a large number of practical clinical questions remain. It was agreed that the best way to address these was to conduct a Delphi exercise . The results have been integrated into the respective sections. Last but not least, advice for patients and pharmacists and a new list of research needs are included.

The GALEN rhinosinusitis cohort: chronic rhinosinusitis with nasal polyps affects health-related quality of life.

BACKGROUND: Chronic rhinosinusitis (CRS) significantly affects health-related quality of life (HRQoL). Few multinational observational studies have evaluated the impact of CRS with nasal polyps (CRSwNP) on patients’ HRQoL. This study aimed to assess HRQoL outcomes (including analyses by disease severity and impact of comorbidities and refractory disease) in CRSwNP patients from a large European database. METHODOLOGY: Data were analysed from the Global Allergy and Asthma European Network (GALEN) Rhinosinusitis Cohort, including sociodemographic data, patient-reported disease severity (visual analogue scale), and scores on the 36-Item ShortForm Health Survey (SF-36) questionnaire. Differences in mean SF-36 scores were evaluated between patients with CRSwNP and population norms and between subgroups of interest (disease severity, comorbidity, and refractory disease, defined by a history of sinonasal surgery). RESULTS: Patients with CRSwNP (N = 445) had significantly lower mean SF-36 Physical Component Summary (PCS) and Mental Component Summary (MCS) scores vs population norms, demonstrating that CRSwNP negatively affects HRQoL. The presence of comorbidities affected HRQoL, as shown by significant differences in PCS scores in patients with asthma or non-steroidal antiinflammatory drug-exacerbated respiratory disease, compared with patients without asthma. Patients with moderate-to-severe disease had significantly lower PCS scores than patients with mild disease. Severe disease had a significant impact on MCS score. History of surgery had a clinically meaningful negative effect on HRQoL compared with no history of surgery. CONCLUSIONS: CRSwNP patients have significantly lower HRQoL compared with population norms. The impact is greater in patients with greater disease severity, comorbidities, or refractory disease.

Modified nasal floor and inferior meatus flap for septal perforation repair. Extension and limits.

BACKGROUND: The nasal floor and inferior meatus (NFIM) flap represents an available option for the reconstruction of a septal perforation (SP). This study explores the feasibility of repairing SPs using a modified simple and extended (including inferior turbinate) NFIM flap. METHODS: An anatomic study was achieved in fresh frozen cadaveric specimens to measure the area and lengths of NFIM flap. The repair of SP with simple and extended NIFM flaps was performed in some of these cadaveric specimens. Preoperative radiological evaluation of CT scans allowed studying the reconstruction limits of the simple or extended NFIM flap. A cohort of patients with SP who underwent reconstruction with an NFIM flap was also included. RESULTS: Complete SP repair with NFIM was achieved in all specimens (n=10). In 38 fresh cadaveric specimens, coronal and sagittal lengths and area of simple NFIM flaps were smaller than in extended NFIM flaps. The radiological analysis of 75 CT scans revealed that the septal height could be reconstructed with a simple and extended NFIM flap. Complete SP repair wasachieved in 5 patients (4 male, mean age 57.4 years) using modified NFIM flaps. CONCLUSION: The simple or expanded NFIM flap represents a feasible option to repair small or medium-sized perforations located at the lower 1/3 or 3/4 of the nasal septum.
