Pneumothorax of the Newborn

The pleural cavity consists of the parietal pleura and the visceral layer, and it is a gas-free potential enclosed lacuna. After pleural rupture for any reason, the formation of pneumatosis in the thoracic cavity after the air enters the pleura is called pneumothorax, which is a common and critical neonatal illness in clinics and a common cause of death among newborns and preterm infants [1, 2].
