There are 2 major sternum deviations: a sternum deviated toward the inside (pectus excavatum) and a sternum deviated toward the outside (pectus carinatum). Both conditions can have a negative impact on lung function (reduced capacity, asthma symptomsâ¦) and heart function (mitral valve prolapse) depending upon the severity. These conditions can also have a negative psychosocial effect because of the cosmetic appearance.
Pectus excavatum is treated surgically and pectus carinatum can be treated surgically or by wearing an external brace.
You may want to consult a thoracic surgeon about this.
