Background:
Primary spontaneous pneumothorax (PSP) has been the subject of many studies, but its pathogenesis remains unclear. Most juvenile PSPs have a tall stature, thin build, and flat thorax, which is described as a "pneumothorax body shape." In this study, we compared the body shapes of spontaneous pneumothorax (SP) patients in their teens and 20s and examined the characteristics of SP patients.
Methods:
Among PSPs operated on in our hospital, we compared the body shapes of males in their teens and 20s. In addition to height, weight, and body mass index (BMI), we measured the size of the thorax using computed tomography (CT) and analyzed the relationship between the two groups and height.
Results:
A total of 77 cases of PSP in teens and 39 cases of PSP in 20s were entered into the study. Teenage PSPs had significantly lower BMI and were slimmer than those in their 20s. However, there were no differences in thorax size and height other than transverse diameter (TD). Furthermore, almost all thorax sizes of PSPs in their 20s were positively correlated with height, whereas those of PSPs in their teens were not correlated except for TD and vertical length.
Conclusion:
The study highlights significant differences in body shape characteristics between teenagers and individuals in their 20s at the onset of SP. These findings emphasize the need for age-specific considerations in the clinical approach to this condition. Further research is required to understand the underlying mechanisms and to optimize treatment strategies accordingly.
