Septoplasty versus non-surgical management for deviated nasal septum: a systematic review and meta-analysis of randomized controlled trials. Eur Arch Otorhinolaryngol 2024:10.1007/s00405-024-08937-x. [PMID: 39230606 DOI: 10.1007/s00405-024-08937-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2024] [Accepted: 08/19/2024] [Indexed: 09/05/2024]
Abstract
PURPOSE This systematic review and meta-analysis of randomized controlled trials (RCTs) aimed to evaluate the efficacy and safety of septoplasty versus non-surgical management for patients experiencing nasal obstruction due to deviated nasal septum (DNS). METHODS We conducted a comprehensive search of PubMed, Scopus, Embase, Web of Science, Cochrane Library, Clinicaltrials.gov, ICTRP, and ISRCTN for relevant RCTs. The primary outcomes included the Nasal Obstruction Symptom Evaluation (NOSE) scale, Sino-Nasal Outcome Test (SNOT-22), Peak Nasal Inspiratory Flow (PNIF), surgical complications, and quality of life. Data were synthesized using RevMan 5.4 and STATA 18, with effect estimates presented as mean differences (MD) or risk ratios (RR) with 95% confidence intervals (CI). The study protocol was registered with PROSPERO (ID: CRD42024538373). RESULTS Our search identified 537 studies, of which 3 RCTs involving 721 participants met the inclusion criteria. The meta-analysis revealed that septoplasty significantly improved NOSE and SNOT-22 scores compared to non-surgical interventions at 6 and 12 months of follow-up, despite no notable differences at 3 months post-treatment. No significant difference was observed regarding nasal flow assessed by PNIF. The rate of complications was low, ranging from 0.31% (revision rate) to 4.12% (bleeding and infection rates). Additionally, our qualitative synthesis showed an improvement in the quality of life at 6 and 12 months in the septoplasty group compared with the non-surgical group. CONCLUSIONS This systematic review and meta-analysis of 721 patients revealed the efficacy of septoplasty, with or without turbinate surgery, in improving nasal obstruction symptoms at 6 and 12 months. Additionally, septoplasty consists of a relatively low rate of complications such as bleeding, infection, and septal perforation. Furthermore, a low revision rate was found. Septoplasty improved the quality of life, especially after 6 and 12 months. However, our findings should be interpreted with caution, and further research is needed to consolidate our results.

Abstract
Nasal obstruction is the subjective perception and objective state of insufficient airflow through the nose. Nasal congestion, conversely, describes a state of not just inadequate airflow or obstructive phenomena but also pressure- and mucus-related states to the patient. Nasal receptors belonging to the transient receptor potential (TRP) protein family mediate the sense of nasal patency via the trigeminal nerve. The transient receptor potential melastatin-8 (TRPM8) responds to temperatures around 8°C to 22°C, and is stimulated by menthol and other cooling agents. The radiant effects of airflow create heat loss to activate these receptors and humans perceive this as nasal patency rather than the direct detection of airflow. The thermovascular state of the mucosa, in conditions such as rhinitis, influence TRPM8 activation. Nasal endoscopy can show signs of rhinitis and should be considered an essential part of the workup of nasal congestion. Efforts to relieve nasal congestion need to manage the mucosal state and surgery needs to ensures that the nasal cavity mucosa is exposed to the cooling effects of airflow rather than simply creating a passage to the nasopharynx.

Abstract
BACKGROUND Septoplasty is used to correct nasal obstruction from nasal septum deviation. However, the long-term efficacy of septoplasty is unclear, and no literature reviews have examined long-term outcomes of septoplasty with or without turbinate modification. This systematic review aimed to evaluate the long-term efficacy of septoplasty with or without turbinate modification in improving nasal obstruction. DATA SOURCES PubMed, EMBASE, Cochrane CENTRAL. METHODS A systematic review of the literature was conducted using the aforementioned databases. Studies reporting outcomes 12+ months after functional septoplasty with or without turbinate surgery for nasal obstruction were included. Septorhinoplasties, concurrent sinus surgery, pediatric studies, and studies where septoplasty was performed for indications other than nasal obstruction were excluded. RESULTS After screening, 35 studies with 4,432 patients were included. Mean weighted post-operative follow-up time was 29.1 months (range 12-120 months). All studies reported significant improvement in subjective and objective outcomes at long-term follow-up compared to baseline. When comparing short-term (<12 months) to long-term (≥12 months) outcomes, four studies noticed that subjective outcomes worsened slightly over time, but no study found a significant change in objective outcomes over time. In addition, 23 studies reported patient satisfaction and/or improvement rates, with 75.4% (2,348/3,113) of patients expressing satisfaction/improvement at an average of 27.0 months after surgery. CONCLUSIONS Overall, septoplasty with or without turbinate modification shows significant improvement in obstructive symptoms at long-term follow-up per both objective and subjective measures. Whether outcomes may worsen slightly over time remains indeterminate based on mixed results in the literature. LEVEL OF EVIDENCE N/A Laryngoscope, 134:2525-2537, 2024.

Quality-adjusted life years and surgical waiting list: Systematic review of the literature. World J Gastrointest Surg 2024; 16:1155-1164. [PMID: 38690041 PMCID: PMC11056653 DOI: 10.4240/wjgs.v16.i4.1155] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/28/2023] [Revised: 01/26/2024] [Accepted: 02/25/2024] [Indexed: 04/22/2024] Open
Abstract
BACKGROUND The quality-adjusted life year (QALY) is a metric that is increasingly used today in the field of health economics to evaluate the value of different medical treatments and procedures. Surgical waiting lists (SWLs) represent a pressing problem in public healthcare. The QALY measure has rarely been used in the context of surgery. It would be interesting to know how many QALYs are lost by patients on SWLs. AIM To investigate the relationship between QALYs and SWLs in a systematic review of the scientific literature. METHODS The study was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Statement. An unlimited search was carried out in PubMed, updated on January 19, 2024. Data on the following variables were investigated and analyzed: Specialty, country of study, procedure under study, scale used to measure QALYs, the use of a theoretical or real-life model, objectives of the study and items measured, the economic value assigned to the QALY in the country in question, and the results and conclusions published. RESULTS Forty-eight articles were selected for the study. No data were found regarding QALYs lost on SWLs. The specialties in which QALYs were studied the most in relation to the waiting list were urology and general surgery, with 15 articles each. The country in which the most studies of QALYs were carried out was the United States (n = 21), followed by the United Kingdom (n = 9) and Canada (n = 7). The most studied procedure was organ transplantation (n = 39), including 15 kidney, 14 liver, 5 heart, 4 lung, and 1 intestinal. Arthroplasty (n = 4), cataract surgery (n = 2), bariatric surgery (n = 1), mosaicplasty (n = 1), and septoplasty (n = 1) completed the surgical interventions included. Thirty-nine of the models used were theoretical (the most frequently applied being the Markov model, n = 34), and nine were real-life. The survey used to measure quality of life in 11 articles was the European Quality of Life-5 dimensions, but in 32 articles the survey was not specified. The willingness-to-pay per QALY gained ranged from $100000 in the United States to €20000 in Spain. CONCLUSION The relationship between QALYs and SWLs has only rarely been studied in the literature. The rate of QALYs lost on SWLs has not been determined. Future research is warranted to address this issue.

Abstract
OBJECTIVE Septoplasty is the most frequently performed ENT surgery to correct nasal septal deviation (NSD). The present study aimed to quantify the effectiveness of septoplasty with or without turbinate surgery according to NOSE questionnaire scores, with the hypothesis that it is able to clinically improve patient-reported nasal obstructive symptoms in the post-operative follow-up. METHODS An electronic search was performed on PubMed/MEDLINE, Embase, and Cochrane Library. The primary outcome was the change in NOSE score at 6 months after surgery. It was assessed with the mean difference (MD) between baseline and postoperative results. RESULTS A total of 2577 patients (males: 65.1%, 95% CI: 59.9-70.2) with a mean age of 33.3 years (n = 1456, 95% CI: 30.4-36.2) were included in this meta-analysis. The pooled baseline NOSE mean score was 68.1 (n = 2577, 95% CI: 64.3-71.9). The pooled MD in NOSE score at 6-months follow-up compared to baseline was -48.8 (n = 1730, 95% CI: -54.6 to -42.9). CONCLUSIONS Functional septoplasty with or without turbinate surgery shows a critical improvement of obstructive symptoms and quality of life according to the validated NOSE score.

Abstract
OBJECTIVE Septoplasty is a surgical procedure to correct the deviated nasal septum (DNS). There are two main approaches to address septoplasty - conventional (CS) and endoscopic septoplasty (ES). This study is aimed to compare the perioperative complications following the two techniques, compare postoperative nasal obstruction between the two approaches, and assess the quality of the available evidence. METHODS A systematic literature search was carried out across multiple databases by independent investigators. We extracted relevant articles that compared conventional septoplasty to endoscopic septoplasty. Cochrane risk of bias tool (RoB2) and Newcastle Ottawa Scale (NOS) was used for the quality assessment of randomized and non-randomized studies, respectively. The objectives comprised immediate surgical complications, surgical length, postoperative nasal obstruction, and quality of life. We incorporated follow-up periods into the univariate meta-regression analyses. RESULTS A total of 2055 patients from 28 studies were included in this study. The endoscopic technique showed significantly lower risks of surgical complications. No difference was found in surgical length (3 studies MD 6minutes [95%CI -25-14], P=0.57). Postoperative nasal obstruction was lower in ES but varies with the follow-up periods. Functional assessment scores using NOSE and quality of life were similar between the two approaches. Risk of bias assessment of the included studies showed an overall moderate- to high-risk of bias. CONCLUSION Endoscopic septoplasty demonstrates a lower risk of complications. Long-term benefits of nasal obstruction were likely similar in the two techniques. Further high quality of studies is still warranted, and conclusions should be taken with discretion given the low quality of the included studies in this present meta-analysis.

Abstract
Background: Large-scale studies characterizing septoplasty revision rates are lacking. Objectives: To identify rates of septoplasty revision in the United States. Methods: Patients undergoing initial septoplasty between January 1, 2007 and December 31, 2013 were identified using the IBM® MarketScan® Commercial Database. Patients were excluded if they had nasal vestibular stenosis, rhinoplasty, or costal cartilage grafts for the initial surgery, or did not have either septoplasty, nasal vestibular stenosis, rhinoplasty, and/or costal cartilage grafts for the second surgery. Results: 295,236 patients received an initial septoplasty, and 3213 (1.1%) patients underwent a revision. Among the revision group, 178 (5.4%) patients received a septorhinoplasty, among which 13 (7.3%) required a costal cartilage graft. Older patients were less likely to need revision surgery (RS). Patients in the Northeast and West were significantly more likely than patients in the Midwest to undergo RS. Insurance plans such as comprehensive and point-of-service were associated with greater odds of RS, whereas others such as high-deductible health plans were associated with lower odds. Conclusion: Septoplasty revision rates are relatively low at 1.1% but influenced by age, region, and insurance plan.

Abstract
Importance: Septorhinoplasties are performed for functional, aesthetic, or a combination of these indications. As a nonvital intervention, cost-effectiveness may be questioned. Objective: To determine the cost-effectiveness of septorhinoplasty. Design and Setting: The literature was reviewed for revision rates (RRs) and health utility values (HUVs) for both septorhinoplasty and revision septorhinoplasty. Age-specific mortality rates and life expectancies were used. Costs were gathered from international settings and analyzed in an adapted Markov model. Intervention: Septorhinoplasty versus no intervention. Main Outcomes and Measures: Cost-efficiency was calculated for different willingness-to-pay thresholds in a probabilistic sensitivity analysis. The effect of different parameters (costs, RRs, HUVs, age, gender) were reviewed and addressed in a sensitivity analysis for an incremental cost-effectiveness ratio (ICER) willingness-to-pay threshold of $50,000/quality-adjusted life year (QALY). Results: The ICER for septorhinoplasty for a 40-year-old woman ranges from $1216 to $3509/QALY (depending on the country) in comparison with no intervention. Septorhinoplasty is cost-effective in 98.8% (for a $50,000/QALY threshold). The sensitivity analysis showed high robustness of the cost-effectiveness for various scenarios. Conclusions and Relevance: Septorhinoplasty is a highly cost-effective treatment.
