Optimizing reconstruction of oncologic sternectomy defects based on surgical outcomes

Area of Science:

• Thoracic surgery
• Surgical oncology
• Reconstructive surgery

Background:

• Optimal strategies for oncologic sternectomy reconstruction remain unclear.
• Key factors influencing reconstruction include skin replacement needs, bony defect size, and internal mammary vessel status.

Purpose of the Study:

• To characterize oncologic sternectomy reconstruction strategies.
• To identify patient and treatment selection criteria for optimal outcomes.
• To develop a generalized management algorithm for sternectomy reconstruction.

Main Methods:

• Retrospective review of 49 oncologic sternectomy reconstructions over 10 years.
• Analysis of patient, defect, and treatment factors using regression models.
• Development of a management algorithm based on identified criteria.

Main Results:

• Most sternectomies were partial (74%); 82% required skeletal reconstruction.
• Pectoralis flaps were common for intact skin defects; free flaps used more for total/subtotal defects.
• Complication rates were similar for partial and total/subtotal sternectomies (44% vs 46%).

Conclusions:

• Total/subtotal sternectomies yield equivalent postoperative complications with appropriate soft-tissue reconstruction.
• Defect-characteristic-matched reconstructive strategies achieve good surgical and oncologic outcomes.
• Tailored reconstruction is crucial for complex oncologic sternectomy cases.
