Abstract

Objective To measure the anatomical parameters of the thorax by an imaging method, calculate the thoracic ratio, and explore the clinical significance. Methods The computed tomography films of 560 people undergoing medical examinations and 368 patients with primary spontaneous pneumothorax (PSP) were selected in Zhejiang Province and Jiangsu Province. They were grouped according to gender and age. The anteroposterior diameter and the transverse diameter of the thoracic cage were measured at the level of the sixth thoracic vertebra, and the thoracic ratio was calculated for statistical analysis. Results The reference range of normal thoracic ratio was (1.62±0.14). There were significant differences in thoracic ratio between male (1.60±0.14) and female (1.67±0.18) (P<0.01) according to the result of one-Way ANOVA. The thoracic ratio decreased with the increasing of age, and there was prominent difference in thoracic ratio between different age groups (P<0.01). The thoracic ratio of patients with primary spontaneous pneumothorax was (1.79±0.20). There were significant differences in the thoracic ratio between patients with primary spontaneous pneumothorax and normal thoracic ratio among different age groups (P<0.05). Conclusions The establishment of the reference value of normal thoracic ratio can provide a reliable reference for the related diseases of thoracic deformity.
