The chest deformity was expressed by the thorax aspect ratio oftransverse plane, the span in lateral plan to span in post-anterior plane. Student t test and correlation were applied in this clinical study.Results: the Mean thorax aspect ratio (MTAR) of the patients with spontaneous pneumothorax is 0.40, MTAR in healthy people is 0.48, the difference of MTAR between two groups is statistically significant, P<0.001.Conclusions: youth with a flat chest has a higher incidence of spontaneous pneumothorax, especially in males.
