Our experience using tissue expansion in reconstructive surgery

Area of Science:

• Plastic surgery
• Regenerative medicine
• Biomedical engineering

Background:

• Tissue expansion is a physiological process relevant to pregnancy, tumor growth, and reconstructive surgery.
• Increasing prevalence of post-burn and post-traumatic defects necessitates advanced reconstructive techniques.
• Tissue expanders, since their introduction in 1957, offer a solution for defects lacking sufficient surrounding tissue for flap reconstruction.

Purpose of the Study:

• To highlight the established role of tissue expansion in plastic surgery.
• To emphasize the benefits of tissue expansion for covering soft tissue defects.
• To discuss the application of tissue expansion in managing complex reconstructive challenges.

Main Methods:

• Surgical implantation of tissue expanders beneath the skin.
• Gradual inflation of the expander to stretch surrounding tissues over time.
• Subsequent surgical removal of the expander and reconstruction using the expanded tissue flap.

Main Results:

• Successful coverage of large soft tissue defects with tissue matching surrounding characteristics (color, thickness, elasticity).
• Minimization of new scar formation compared to traditional methods.
• Reduced donor site morbidity, preserving healthy tissue elsewhere on the body.

Conclusions:

• Tissue expansion is a versatile and effective technique in plastic surgery for soft tissue reconstruction.
• It provides a method for defect coverage with aesthetically and functionally superior outcomes.
• The technique is crucial for managing complex defects resulting from trauma, burns, or tumor resection.
