Chest symptoms: rib ectropion will cause chest tightness and stuffiness. 2. Respiratory symptoms: rib ectropion will lead to the restriction of thoracic growth, and then the development of lungs will be hindered, which will lead to the obstruction of gas exchange in the body, and the lung capacity will be reduced, which will easily lead to the emergence of respiratory infections, colds, coughs and other symptoms. 3. Affecting aesthetics: rib ectropion often leads to deformity of the ribs, which affects aesthetics when exposed to the surface of the body.
