Immediate reconstruction of full-thickness chest wall defects

Area of Science:

• Thoracic surgery
• Reconstructive surgery
• Biomaterials in medicine

Background:

• Full-thickness chest wall defects pose significant reconstructive challenges.
• Historically, reconstruction involved various materials and techniques with varying success rates.
• The advent of advanced flap and stabilization methods has evolved treatment paradigms.

Purpose of the Study:

• To evaluate the efficacy of different chest wall reconstruction techniques over a ten-year period.
• To assess the role of Marlex mesh in chest wall stabilization.
• To compare outcomes of random versus axial pattern flaps and myocutaneous free flaps.

Main Methods:

• Retrospective review of 21 patients undergoing chest wall reconstruction.
• Analysis of Marlex mesh utilization for stability.
• Comparison of flap types: random pattern, axial pattern, myocutaneous, and myocutaneous free flaps.
• Assessment of complications such as flap necrosis and ventilatory insufficiency.

Main Results:

• Marlex mesh provided stability in 5 patients; not required in 9 with radiation ulcers due to pleural fibrosis.
• Partial sternectomies did not necessitate Marlex, but total sternectomy led to insufficiency without stabilization.
• Random pattern flaps had 36% necrosis; newer techniques, including myocutaneous free flaps, showed no necrosis.
• Myocutaneous free flaps provided stable coverage for large, contaminated defects.

Conclusions:

• Immediate repair of full-thickness chest wall defects is feasible with current flap and stabilization techniques.
• Myocutaneous free flaps offer reliable and complication-free coverage and stability.
• Careful consideration of stabilization is crucial, especially after total sternectomy.
