In theory, if the pectus excavatum surgery is successful, there won't be many long-term complications. However, if we have to discuss possible complications or side effects, they can be categorized as either short-term or long-term. For instance, pectus excavatum itself involves the inward and backward indentation of the sternum, which compresses the patient's heart and lungs. The surgery corrects this by pushing or suspending the indented sternum forward. Due to the alteration in the shape and appearance of the bones, the patient may experience some pain post-surgery, but this pain is bearable and usually subsides within three to five days. Particularly in younger children, who have softer bones, normal activities can often be resumed in just a day or two. However, as age increases and bones become harder, patients may feel pain for about three to five days to a week post-surgery, but typically return to normal after a week. Additionally, there might be complications such as pneumothorax, pleural effusion, or even severe cardiac damage. However, these are generally problems that arise from unsuccessful operations or issues that can be resolved in the short term. Therefore, in the long term or over an extended period, there are generally no lasting side effects from pectus excavatum surgery. If there has to be mention of any, it would be the surgical scars left under the armpits, typically one to two scars each measuring 1 to 2 centimeters.

How to exercise to correct pectus excavatum

Pectus excavatum refers to the inward and backward indentation of the sternum, a deformity that can compress the patient's heart and lungs. To exercise for pectus excavatum, patients are advised to practice deep breathing exercises to enhance lung function, as well as engage in appropriate running and routine physical activities to strengthen heart function. However, in cases of severe pectus excavatum which severely compresses the heart, even pushing it entirely to the left side, patients may not be able to tolerate running and other intense activities. Therefore, it is quite difficult to completely correct pectus excavatum through exercise alone. Some parents might think that doing push-ups can correct pectus excavatum, but push-ups make the pectoral muscles on both sides stronger, and since these muscles pull outward, the force is not directed in the same way as the inward and backward indentation of pectus excavatum. Furthermore, continuously training the pectoral muscles causes them to develop, and the resultant thickening of the muscles on both sides can exacerbate the inward and backward indentation of the sternum in the middle. Thus, after appropriate cardiovascular and pulmonary exercises, those with severe pectus excavatum should still consult a doctor for active advice and consider surgical treatment options.

Can people with funnel chest work?

Whether pectus excavatum can affect work depends on two aspects. Firstly, if it is a mild case of pectus excavatum, with an index less than 3.25, such mild conditions do not cause significant compression on the heart or lungs, and the patient will not have too many work-related issues. However, if the pectus excavatum index is greater than 3.25 and the chest is sunken inward and backward, significantly compressing the heart and lungs, such a condition prevents the heart from fully relaxing and the lungs from fully expanding, which can impact the patient's activities. Besides the physiological impact, this condition can also significantly affect social interactions, especially for young children or adults. Some patients may suffer severe inferiority complexes, depression, and even suicidal tendencies, which, of course, will also affect their work capability and state. Therefore, for severe cases of pectus excavatum, it is recommended to wait until after treatment to return to work. Once the pectus excavatum is corrected, and the heart and lung functions are no longer compressed, and the appearance is normalized, the patient's work capability should be completely fine.

What should be noted for pectus excavatum in daily life?

The biggest difference between children with pectus excavatum and normal children lies in the middle chest bone structure sinking backwards and inward toward the spine, creating a deformity where the front chest and the back compress each other. Naturally, this completely compresses the normal position of the heart and lungs. Therefore, the heart of such children is compressed and deformed, pushing the entire heart to one side. We have encountered clinically cases where there are just a few millimeters of space between the sternum and the spine, leaving no room for the heart, thus completely compressing and pushing it to the left side. Imagine a heart, completely compressed and deformed, where the valves inside cannot function normally. Hence, some children may exhibit insufficiencies in their tricuspid and mitral valves. Therefore, in children with pectus excavatum, their heart is under pressure, their valves deformed, leading to poor cardiac function, and their lung function is also compromised. Since the lungs also need space to expand, lungs that are completely compressed cannot fully relax, resulting in such children having poor cardiac and lung functions, reduced exercise endurance, and since the lungs cannot fully expand, such children are prone to catching colds. Thus, for children with pectus excavatum, it is important to avoid catching colds. Moreover, treating the root cause of the condition, which is pectus excavatum itself, is crucial. Therefore, correcting pectus excavatum early on is essential.

How to exercise the pectoral muscles with pectus excavatum?

How to exercise the pectoral muscles with pectus excavatum, we know that the indentation of pectus excavatum is concave inward and backward, that is, the front sternum in the middle of a person's chest compresses backward towards the spine. Exercising the pectoralis major muscle aims to lift the muscles on both sides of the sternum, but the attachment point of the pectoralis major actually pulls from the ribs outward and upward towards the humeral tuberosity of the arms. This type of lifting actually pulls the force of the ribs or a part of the sternum outward, and it cannot pull forward. Indeed, the forward force is the direction truly needed when correcting pectus excavatum. Therefore, patients with pectus excavatum can exercise the pectoralis major, do push-ups, and perform dumbbell fly exercises, which are all feasible. However, such exercise will only make the pectoral muscles thicker and the force is directed sideways, and it cannot effectively pull the downward and inward-concaved sternum forward. Therefore, although individuals with pectus excavatum can perform exercises like push-ups and dumbbell flies like normal individuals, these exercises should not be expected to significantly improve pectus excavatum. Moreover, current medical technology and trials have not found exercising the pectoralis major to have a substantial corrective effect on pectus excavatum.

Can funnel chest heal itself?

Actually, a portion of children with pectus excavatum can heal on their own, especially those who are newly born and discovered to have pectus excavatum. This is because children are curled up while in the mother's womb. In some cases, their hands and feet might be placed in front of the sternum, pressing it backward and inward, causing a deformity. However, once the mother gives birth and the child's limbs unfold, the pressure on the sternum is relieved. As the chest grows, it gradually returns to its normal shape, and these children with pectus excavatum can be cured. On the other hand, another group of patients do not have pectus excavatum at birth, but develop a noticeable chest indentation as they grow older. These patients, when they are young, can also be treated with conservative methods, such as using a vacuum bell for pectus excavatum to gradually draw the indentation outward. With its stabilizing effect, as the child grows, the deformity can be slowly corrected. Of course, there are also children who might have a more rapid skeletal development, and essentially become "set" in their ways. At this stage, they may require surgical intervention to treat the condition. In summary, a portion of pectus excavatum patients can be healed, while another portion requires active intervention and treatment.
