Abstract

Background
Deviated nasal septum causes variable resistance to inspired air currents, which directly and indirectly influences the efficiency of pulmonary functions.
Aim
To compare pulmonary function tests performed before and following septoplasty with turbinectomy in patients complaining of nasal obstruction caused by a deviated septum with hypertrophic inferior turbinate.
Patients and methods
The study was conducted on 60 patients diagnosed with deviated nasal septum with hypertrophied inferior turbinate. All were subjected to complete history taking, external nasal examination, and anterior rhinoscopy, which was performed with a nasal speculum. Additionally, all patients in this study underwent a nasal endoscopy, computed tomography, and spirometry.
Septoplasty and turbinectomy were performed for all cases with regular follow‑up, and the spirometry was repeated after 3 months.
Results
After surgery, the preoperative forced vital capacity (FVC) of 3.14±0.70 increased to 4.43±1.01, with a highly statistically significant difference (P<0.001). Forced expiratory volume in the first second (FEV1) was significantly greater postoperatively (2.66±0.55) than preoperatively (3.96±0.81) (P<0.001). The preoperative FEV1/FVC ratio of 85.08±5.47% improved to 90.39±8.75% after surgery, with a statistically significant increase (P=0.001). The preoperative peak expiratory flow rate of 5.57±1.47 increased to 7.07±2.26 following surgery, a difference that was highly statistically significant (P<0.001). The preoperative forced expiratory flow of 25–75% of vital capacity of 2.73±1.13 increased to 3.73±1.28 after surgery, a change that was highly statistically significant (P<0.001).
Conclusion
FVC, FEV1, FEV1/FVC, PEF, and forced expiratory flow of 25–75% showed a significant increase after operation.
