Laminated Marlex-methyl methacrylate prosthesis for massive chest wall resection

Area of Science:

• Surgical reconstruction
• Biomaterials science
• Thoracic surgery

Background:

• Extensive anterolateral resections can compromise chest wall integrity.
• Previous reconstruction methods may lack stability or aesthetic appeal.
• High-dose irradiation can complicate tissue healing and reconstruction.

Observation:

• A novel technique involves sandwiching room temperature-curing methyl methacrylate between Marlex mesh layers.
• This composite material is molded intraoperatively to conform to the chest wall defect.
• Coverage is achieved using a latissimus dorsi myocutaneous flap.

Findings:

• The methyl methacrylate-Marlex mesh composite provides firm and stable chest wall reconstruction.
• The reconstruction is aesthetically pleasing and practical to perform.
• This technique is effective even in patients who have undergone high-dose irradiation therapy.

Implications:

• This approach offers a reliable and versatile solution for complex chest wall defects.
• It enhances patient outcomes by restoring structural integrity and improving aesthetics.
• The technique's applicability to irradiated patients expands reconstructive options in challenging cases.
