The purpose of this paper was to investigate ultrasonography morphological findings in patients with idiopathic CTS and comparing some physical properties such as age, gender, BMI with dominancy in the hands. Materials and methods: This research was a cross sectional study that conducted in Al-Zahra hospital. 125 patients who came to ultrasonography department for any reason were studied randomly and selected by a convenience method. The thickness of median nerves of these patients was measured by ultrasonography and analyzed based on age, sex, BMI and dominancy and non-dominancy in hand for each patient separately as main aim of our study. The data collected entered to computer and analyzed by SPSS software. The chi- square and t-student tests were used for data analysis. Results: The mean cross-sectional area of right median nerve in right-handed patients was 0.063±0.02 cm2 and for left median nerve in the same group was 0.056±0.022 cm2. Results demonstrates differences in cross-sectional area of median nerve in dominant hand in comparison to non-dominant-hand in right-handed ones (P LA eng UL http://jbrms.medilam.ac.ir/article-1-109-en.html M3 ER -
