This depends on several factors; the position of the chest wall deformity, its severity, the flexibility of the chest, the kind of results wanting to be achieved and the age of the person undergoing treatment for pectus excavatum or pectus carinatum. Early adolescence (roughly between the ages of 12-16 years old) – is an optimum age to start treatment, given that the chest is still maturing, and flexible, permanent correction is more easily achievable. Once bracing treatment is complete and a patient has stopped growing, the deformity will not return. For younger pectus patients, conservative bracing is used to keep a deformity from worsening and can help them to avoid surgery in later life. For older pectus patients (between the ages of 20 to 30) results can be harder to achieve, as the costal cartilage hardens into the bone as a person matures. Over the years we have successfully treated many adults for both pectus excavatum and pectus carinatum and active adults with flexible chests can expect good results.
