Hi doctor! May I ask: "Can I fix it when I am 31 years old with a concave sternum?". Thanks for the advice and answers!

Pectus excavatum or sternum dentata is a congenital chest deformity that appears from childhood with the manifestation of a deep depression in the middle of the chest. If not treated promptly, congenital pectus excavatum causes aesthetic deformity and affects the development of the body.
