There are various thoracic deformities with different morphologies, each of which can be divided into symmetrical and asymmetrical types. The surgery for symmetrical deformities is relatively simple, and there are many proven methods to complete the surgery. However, for asymmetrical deformities, despite many attempts, the surgical results are not satisfactory. In order to achieve a satisfactory correction of asymmetrical deformities, a special surgical method for asymmetrical deformities was designed. The concept of this procedure is mainly to dissolve the previous global systemic treatment into a localized treatment of the lesion in order to obtain a more refined and satisfactory result. Our approach was first applied to patients with unilateral thoracic dysplasia, including asymmetric funnel chest, and asymmetric pectus excavatum. We envisioned to change the shape of the deformed thorax with a special support material. In order to achieve this goal, we have developed various designs for specific methods. These design considerations include: (1) the force problem of the support; (2) the position of the support; (3) the relationship between the position of the support and the scapula; (4) the length and shape of the support itself; and (5) the specific method of the support placement. After clinical application in many patients, it has been proved that our design is a very effective surgical method. This method can be used for almost all asymmetrical thoracic deformities, including patients with funnel chest, flat chest, and pectus excavatum. In addition, this procedure has been shown to have excellent surgical results in patients with some severe thoracic deformities. The promotion of this method will be a real benefit for patients with thoracic deformities.
