Intrathoracic defects continue to provide one of the most challenging problems faced by the reconstructive surgeon, particularly in the presence of bronchopleural fistula. We review the principles of management of bronchopleural fistulae and empyema, with an emphasis on the Clagett principle, pedicled and free muscle flaps, and the concept of a "designed air fistula" in bronchopleural fistula management. Although the importance of muscle flap closure in intrathoracic defects is undisputed, the timing and relative superiority of muscle flap closure versus conventional thoracic-surgical techniques remains an unanswered question.
