Septoplasty is a common surgical procedure performed to correct deviated nasal septum (DNS), a condition that can cause chronic nasal obstruction, impaired breathing, and reduced quality of life. By restoring nasal alignment, the surgery aims to im prove airflow and reduce symptoms of obstruction. This review evaluates current evidence on the functional outcomes of septoplasty, with particular emphasis on respiratory ef ficiency and exercise performance. A systematic literature search was conducted in PubMed and Google Scholar databases, covering studies published between January 2008 and February 2025. The initial search yielded 428 records, of which 37 peer-reviewed studies met predefined inclusion criteria and were included in the final analysis. Most demonstrated consistent improvements in nasal airflow, as measured by tools such as the NOSE scale, PNIF, rhinomanometry, and spirometry (e.g., FEV1 , FVC). Some reports also noted better performance in functional assessments such as the six-minute walk test (6MWT), with postoperative increases of up to 48 meters. While improvements in nasal breathing are well-established, direct evidence linking septoplasty to enhanced exercise perfor mance - especially in athletes - remains limited but promising. Current findings are constrained by study heterogeneity, small sample sizes, and a lack of randomized trials focused on athletic populations. In conclusion, septoplasty effectively relieves nasal obstruction and may improve respiratory efficiency in both daily life and physical activity. Although existing data suggest potential benefits for athletic performance, further prospective studies with ob jective outcome measures are needed to confirm these effects in competitive settings.
