“…[5,8] Beyond one year, autologous grafts (costal cartilage, parietal skull, tibial periosteum) or prosthetic materials such as Marlex mesh, Teflon mesh, silicone elastomer and acrylic are required. [5][6] Moreover, studies have suggested that it is always preferable to use autogenous tissue for sternal cleft repair and to avoid the use of prosthetic materials, recognising the risk of infection and the negative impact of inert material on the patient's development. [1,4,8] Despite the risk of infection described in the literature, the use of prosthesis in sternal cleft repair has an advantage in preventing an increase in intrathoracic pressure such as explained in our technical note.…”
