What surgical approach may be employed to excise infected costal cartilage and xiphoid?

• A. Thoracoabdominal Incision
• B. Median Sternotomy
• C. Laparoscopy
• D. Thoracotomy

Answer: (A)

A thoracoabdominal incision provides wide exposure of the anterior chest wall, including the lower sternum, xiphoid, and multiple costal cartilages. This broad access is essential when removing infected costal cartilage and the xiphoid because it allows en bloc resection and thorough debridement across the midline and lateral chest wall, with room for reconstruction if needed. Median sternotomy mainly opens the mediastinum through the midline and offers limited lateral exposure to the costal margins, which can hinder complete resection of infected cartilage. A thoracotomy gives access to one side of the chest wall but may not provide adequate exposure of the xiphoid and bilateral costal cartilage. Laparoscopy targets the abdominal cavity and cannot adequately address anterior chest wall infection. Therefore, the thoracoabdominal approach is the most suitable for excising infected costal cartilage and the xiphoid.
