Some observations show increased, some show decreased and other studies show no changes in the dynamic respiratory flows.In this study we evaluated lung volumes before and after surgery. We also evaluated the correlation of repiratory lung volume changes with mean of Cobb's angle.Patients and Methods: In this observational descriptive study, 18 non smoker patients with idiopathic scoliosis were included. Cobb's angle, lung volume and flow were measured before and after surgery with spirometer. Paired t-test was used for statistical analysis. To consider height and weight changes during the follow ups, we used percentage relative to normal instead of absolute volumes.Results: From 30 patients included in this study we followed 18. Mean follow up duration was 34.5±19.6 months (SD=19.6) Dynamic volume changes were: VC=13.4 SD=8.6 (P %> http://rjms.iums.ac.ir/article-1-1071-en.pdf %P 125-131 %& 125 %! %9 Research %L A-10-312-16 %+ %G eng %@ 2228-7043 %[ 2009
