[Subjective and objective comparative analysis of nasal ventilation function before and after nasal septoplasty].

To investigate the changes of nasal ventilation before and after septoplasty by using NOSE scoring scale and nasal function examination, and to explore the correlation between subjective nasal obstruction and nasal function examination and its clinical application value. A total of 129 cases of nasal septum deviation from December 2021 to April 2023 in our hospital were selected for study. All patients underwent septoplasty. Nasal obstruction symptom evaluation（NOSE） was performed in all patients before surgery and 3 months after surgery. nasal minimal cross-sectional area（MCA） and nasal cavity volume（NCV） were recorded by nasal acoustic reflex, nasal resistance meter and nasal respiration apparatus, nasal resistance（NR）, distance between the nostril to minimum cross-sectional area,（the distance between the nostril to minimum cross-sectional area, MD）, nasal inspiratory volume（IV）, nasal expiratory volume（EV）, the nasal partitioning ratio, NPR includes objective indicators such as inspiratory volume difference ratio（NPRi） and expiratory volume difference ratio（NPRe）. Paired test was used to compare and analyze the changes of various indicators before and after surgery, and the difference（<0.05） was statistically significant, and Pearson correlation linear analysis was used to analyze the correlation between subjective and objective indicators. There were statistically significant differences in NOSE score, NCV, NR, MD, EV, IV, NPRe and NPRi of 129 patients before and after surgery（<0.05）, while there was no statistically significant difference between MCA before and after surgery（>0.05）. Preoperative NOSE score was correlated with NR, NCV, EV, IV, NPRe and NPRi（<0.05）, but not with MD and MCA（>0.05）. There was correlation between NOSE score and NR, MCA, NCV, EV, IV, NPRe and NPRi（<0.05）, but no correlation between nose score and MD（>0.05）. The subjective NOSE scale combined with nasal function test has certain clinical reference value in evaluating the surgical effect of patients with deviated nasal septum.
