<s>[INST] My 17 year old daughter was just diagnosed with pigeon chest. I was looking online and noticed that there is a new procedure out for this condition that is less invasive than repositioning the breast bone and removing the cartilage. Which procedure is better? [/INST] Thanks for your question on Chat Doctor. I can understand your concern. Honestly speaking, no treatment is required for rectus caricature (pigeon chest). It is developmental defect of rib cage. Surgical correction is very risky and 100% successful correction of the deformity is next to impossible. But if patient is having underlying lung developmental defect, breathlessness, collapsed lung, low oxygen saturation etc. than only surgical correction is required. Just for the cosmetic purpose, better not to go for surgery. And if surgery is indicated than repositioning of breastbone with removal of cartilage is best option. Hope I have solved your query. Wishing good health to your daughter. Thanks. </s>
