Answer: a, d, e

Skeletal chest wall defects that are full-thickness and occur posteriorly where they can be covered by the scapula do not require reconstruction. Anterior chest wall defects do require reconstruction, primarily to stabilize the chest wall and prevent paradoxical motion. The reconstruction should be immediate for optimal physiological benefit. Since Marlex mesh is porous, only a wound catheter is needed as pleural fluid will drain through it. PTFE, however, is a solid sheet necessitating both pleural and wound drainage.
