The latest age of surgery for funnel chest should be before the age of 10, and the best age is at the stage of 2~5 years old. Funnel chest is a congenital disorder, a malformation of fetal development, with incongruous growth of the ribs. The main symptom is that the anterior chest will be significantly depressed, and in individual patients the condition is more serious, and may even lead to abnormal development of the shoulders, back and other tissues. After the discovery of funnel chest, it is recommended to consult the doctor in time to assess the indications for surgery, the age of not more than 10 years old, preferably at the age of 2 to 5 years, when the bones are not yet fully developed, which can ensure that the later development will not continue to show abnormal changes; if the age is too old, more than 10 years old, even if surgical correction, it can not improve the growth of the bones fundamentally. If you have funnel chest, you should go to the hospital in time and consult a specialist for guidance in choosing a reasonable treatment plan.
