About

Pectus deformities are among the most common anterior chest wall pathologies. Pectus excavatum is the most common chest deformity with an incidence of 0.1-0.3%. In severe deformities, a decrease in lung volume is observed. This can cause decreased pulmonary function and affect the function of the right ventricle. The diaphragm is the main respiratory muscle, and diaphragm contraction is associated with respiratory functions. So, investigators aimed to measure diaphragmatic thickness in adolescents with pectus deformity and to show whether diaphragmatic thickness is an early predictor of respiratory disorder in participants who do not show any clinical symptoms or whose respiratory functions are normal.

Full description

Pectus deformities are among the most common anterior chest wall pathologies. Pectus excavatum is the most common chest deformity with an incidence of 0.1-0.3%. It is more common in boys than girls at a ratio of 4:1. This deformity involves the lower part of the body of the sternum; The chest wall has shifted posteriorly.

Pectus excavatum is a cosmetic defect that in most cases does not have physiological consequences. In severe deformities, a decrease in lung volume is observed. This can cause decreased pulmonary function and affect the function of the right ventricle. Funnel chest defects can cause chest pain, shortness of breath, decreased cardiac output, and decreased exercise capacity, depending on the depth of the deformity.

The alignment of the skeletal system in the chest and its harmony with the compliance of the chest wall are related to respiratory function; changes in the rib cage lead to a decrease in lung capacity. The diaphragm is the main respiratory muscle, and diaphragm contraction is associated with respiratory functions. In recent years, ultrasonography (USG) has gained increasing utility for visualizing the diaphragm and assessing its function, with several advantages.

Based on this, investigators aimed to measure diaphragmatic thickness in adolescents with pectus deformity and to show whether diaphragmatic thickness is an early predictor of respiratory disorder in participants who do not show any clinical symptoms or whose respiratory functions are normal.
