Chest wall deformities are a group of conditions that affect the shape and function of the chest wall. They may be congenital, appearing from childhood, such as pectus excavatum (cornuate chest) or pectus carinatum (protruding chest), or acquired as a result of injuries or other diseases. These deformities not only affect appearance but can also impact breathing, exercise capacity, and even self-confidence, especially in adolescents. With significant advancements in thoracic surgery, treatment options have become more precise and effective, ranging from conservative monitoring and treatment to modern, minimally invasive techniques such as endoscopic surgery and the Nuss technique, which achieve excellent results with less pain and a faster recovery period. At our clinic, each case is individually evaluated to determine the best treatment plan that balances medical and cosmetic outcomes, with a focus on patient comfort and safety.
