Funnel chest is a congenital malformation disease, the patient’s appearance is characterized by anterior chest depression, slightly humped back and protruding upper abdomen, generally people will be mistaken for “calcium deficiency”, or misdiagnosed as “special body type” did not get medical treatment. In recent years, minimally invasive Nuss surgery has been carried out in many hospitals in China to treat funnel chest. The best time to operate on a funnel chest is before the development of puberty, i.e., 3-12 years old. Dr. Donald Nuss, the founder of minimally invasive surgery and a renowned pediatric surgeon in the United States, who is regarded as a “milestone in the treatment of funnel chest,” emphasizes that minimally invasive surgery requires considerable pressure on the patient’s heart and lungs, and that irregularities in the operation will result in serious consequences such as heart damage. Funnel chest is often misdiagnosed as calcium deficiency or special body shape According to the introduction, the appearance of patients with funnel chest is characterized by sunken forehead, forward shoulders, slightly hunched back and protruding upper abdomen. It is commonly misunderstood as ‘calcium deficiency’ or ‘special body shape’, but it is actually a disease. As the chest cavity is sunken, it will cause great pressure on the patient’s heart and lungs in a serious situation, which will even affect the patient’s breathing and eating in the long run. That is why patients with funnel chest are generally short and slim. A mild funnel chest may have no symptoms, while a more severe deformity compresses the heart and lungs, affecting respiratory and circulatory functions, reducing lung capacity, increasing functional residual air volume, and reducing activity tolerance. Young children often have recurrent respiratory infections with cough and fever and are often diagnosed with bronchitis or bronchial wheeze. Young children have fewer circulatory symptoms, while older ones can present with dyspnea, rapid pulse, palpitations, and even pain in the precordial region after activity, mainly because the heart is compressed, cardiac blood output cannot meet the needs during exercise, and the myocardium is hypoxic, thus causing pain. Some patients can also develop arrhythmias, as well as systolic murmurs. Leaky chest cannot be cured by itself and needs early treatment The five features of the beautiful Xiao Ting is 16 years old, and no one can see her face without liking her. However, a glance at her whole body produced a great disparity: she grew up with a sunken chest, and from the side, it looked like a “funnel”, without any sense of female beauty. Her parents noticed that her body shape was different when she was young and thought she was deficient in calcium, but the situation got worse instead of better after calcium supplementation. As she grew older, Xiao-ting became more and more inferior, not only reluctant to go to school, but also never set foot outside the house. Because of the chest cavity is sunken, it will cause great pressure on the heart and lungs of the child, and in the long run, it even affects the child’s breathing and eating, so the affected children are short and thin. The disease not only has a great impact on the child’s physical appearance, but also brings a heavy burden on the child’s psychology. Because of their “special body shape”, they rarely go out, dare not swim, and some patients are even afraid to go to school or work for fear of the strange looks around them. Their special body shape also causes them great problems when buying clothes. Due to their extremely low self-esteem, some patients wear thick clothes all year round to hide their body shape to the maximum. Children with the condition are especially prone to psychological depression and fear of strange looks from people. The best time to treat children with funnel chest is between the ages of 3 and 12. If left untreated, surgery will become more difficult as they get older, but the exact timing of surgery requires a detailed analysis by a professional doctor based on the patient’s specific situation before it can be determined. As for adult patients with funnel chest, it is best to have early treatment to relieve the tremendous pressure on the heart and lungs, to improve the quality of life and survival, and also to improve the psychological aspects of stress. However, the reality is that many parents often wait until their child is past the best time for treatment before seeking medical attention due to some misconceptions. Sometimes, after a child with funnel chest is diagnosed, parents are still slow to bring their child for treatment, because many people have the misconception that the symptoms will improve when the child grows up and the funnel chest will disappear naturally. Patients with funnel chest disease should be treated early for better results. Minimally invasive surgery requires a high level of skill. For the treatment of funnel chest, surgery is still the only means. Traditional surgical treatment usually involves making an incision of about 20 cm in the chest, cutting off all the bent ribs, correcting them, and then reattaching the bones and placing them in the chest cavity. Due to the large opening, it puts tremendous pressure on the heart and lungs and requires a high level of cardiac and pulmonary function from the patient. Traditional surgery usually takes 3-6 hours, with heavy bleeding and slow postoperative recovery, and patients need to be bedridden for 2 weeks before they can walk around. In 1998, Dr. Donald Nuss, a renowned pediatric surgeon in the United States, pioneered the minimally invasive Nuss procedure, which only changed the dilemma of surgical treatment for funnel chest. According to Dr. Nuss, the surgery is performed in a minimally invasive manner, under the thoracoscope, the surgeon makes a small incision of about 2 cm from each of the patient’s left and right armpits, and the orthopedic plate is entered through the incision, fixed at both ends, and then removed in about three years. The surgery can be completed in less than an hour, with minimal bleeding, immediate postoperative results, and a short postoperative recovery period so that the patient can get out of bed and walk around the next day.The Nuss procedure was started in China in 2002 and has been widely praised by patients because of the good characteristics of the surgery, so since 2007, about 200 hospitals nationwide have been performing the procedure. Dr. Nuss repeatedly emphasized that this delicate surgery requires a high level of skill and clinical experience, and any weakness in any aspect of the operation may bring the patient A weakness in any aspect of the operation may cause great physical damage and serious psychological trauma to the patient. Nuss minimally invasive surgery must be performed in a large hospital by an experienced surgeon, and the procedure requires a strict and detailed evaluation of the patient’s cardiopulmonary stress capacity.
