determination of the effect of nasal septoplasty on pulmonary artery pressure in patients with deviated nasal septum

background nasal septal deviation (nsd) can cause upper airway obstruction, which results in hypoxia and therefore, pulmonary vasoconstriction, ventricular hypertrophy and right-sided heart failure. objectives the aim of this study is to determine the mean pulmonary arterial pressure (mpap) of the patients with nsd and the effect of septoplasty on pulmonary arterial pressure. patients and methods thirty five patients with nsd (mean age, 31.37 years; 19 men and 16 women) were included in the study. mean pulmonary arterial pressure was measured in the preoperative period and after third month postsurgery. results the preoperative mpap value (23.43 mmhg [sd, 3.84]) was higher than postoperative values (20.17 mmhg [sd, 3.36]). there was a significant decrease in mpap after the surgery (3.26 mmhg). p-value in our study was smaller than 0.001. conclusions nasal septal deviation like other causes of upper airway obstruction such as adenotonsillar hypertrophy affects mpap. nasal septoplasty is effective in reduction of mpap in patients with nsd.
