Patient: Hello, Dr. Tang! My son is four and a half years old, and in the past two years, I have noticed that his chest is a bit concave, and his right side is a bit higher than his left side, and he sometimes snores in his sleep. What is the degree of funnel chest? Do I need surgery? At what age is the surgery suitable? Is it risky? Tang Zhixian, Department of General Thoracic Surgery, Guangzhou Children’s Hospital: Your child has a common type of funnel chest, and now that he is four and a half years old, he should consider surgery because it is generally getting heavier and heavier as he continues to be observed. The best age for surgery is over three years old, before going to school. The name of the surgery is minimally invasive Nuss funnel chest orthopedic surgery, the surgery is definitely risky, but generally safe, the cost is about 30,000.
