Pectus excavatum surgery involves implanting a metal plate in the patient's body; however, this type of metal plate cannot be welded to normal bones or muscles. It is only fixable using stainless steel wires or sutures. Therefore, postoperative care is crucial. Good post-surgical care significantly reduces the chances of the metal plate shifting. We recommend that patients lie flat on their backs for 3 to 5 days after the surgery, avoid bending, twisting their bodies, or rolling over in bed for a week. For a month, it's important for patients to keep their bodies straight and stand flush against a wall. Since the chest will be quite painful after the surgery, standing against a wall helps the patient maintain a proper posture. Otherwise, due to the pain, the patient may stoop forward, resulting in a hunched posture, which is unappealing and not good for the spine. Within two months post-surgery, the patient should avoid bending over to lift heavy objects as this can lead to uneven distribution of force that may cause the metal plate to shift. Intense physical activities should be avoided for three months. The patient should ideally rest in a supine position and avoid external injuries and contact or impact sports like basketball, soccer, or football. Generally, the metal plate should be removed 2 to 3 years after the surgery depending on the circumstances, so regular clinic visits are necessary to monitor the situation of the plate. If the patient experiences difficulty breathing or chest pain after being discharged from the hospital, they should immediately go to the nearest hospital to have their chest x-rayed to check the status of the metal plate.
