RESUMEN
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.
