Costal cartilage is a commonly used filling and supporting material in clinical practice, which has many advantages, but chest wall deformity frequently occurs after autologous costal cartilage harvesting. In order to effectively reduce the incidence of chest wall deformity, experts and scholars have conducted a full exploration.Theauthor reviewed the related literatures and summarized the prevention of chest wall deformity after costal cartilage harvesting. On the basis of reasonable selection of surgical site and cartilage harvesting amount, the costochondral junction(CCJ)and optional cartilage should be preserved.The costal perichondrium should be sutured and autogeneic cartilage debris should be replanted during the operation. In addition, postoperative management should also limit the degree of chest movement and breathing range, such as external fixation and restrictions on physical exercise.
