Nasal obstruction due to septal deviation and a crooked nose affects breathing and quality of life. Objective assessment of surgical outcomes remains essential.This study aimed to evaluate functional and aerodynamic improvements following surgery using subjective and objective tools. Primary outcomes included changes in the Turkish validated Standardized Cosmesis and Health Nasal Outcomes Survey (T-SCHNOS) scores, nasal resistance, and airflow patterns.A retrospective cohort study was conducted following the STROBE guidelines.Eight patients were assessed pre- and postoperatively using T-SCHNOS, 4-phase rhinomanometry (4-PR), and computational fluid dynamics (CFD). Five were tested under decongested and three were tested under nondecongested conditions. Four healthy individuals served as controls. CFD models were generated from DICOM data.Significant improvements were seen in T-SCHNOS, RMOS, Qdiff, and Vmax (p r = 0.660), but other CFD-clinical parameter correlations were weak. Surgery significantly improves airflow metrics, although subjective-objective correlations vary.
