Tissue expanders in reconstruction of burn sequelae

Area of Science:

• Plastic Surgery
• Reconstructive Surgery
• Biomaterials

Background:

• Burn scars present significant reconstructive challenges.
• Tissue expanders are utilized to address soft tissue deficits in reconstructive surgery.
• Evaluating the efficacy and complications of tissue expanders in burn scar treatment is essential.

Purpose of the Study:

• To assess the outcomes and complication rates of tissue expander use in patients with burn scars.
• To identify factors influencing the success and complications of tissue expander implantation for burn scar reconstruction.

Main Methods:

• Retrospective analysis of 33 tissue expander implantations in 21 patients (20 with burn scars, 1 with a fresh burn).
• Evaluation of expansion goals achieved, complication types and incidence, and management strategies.
• Analysis of factors contributing to major and minor complications.

Main Results:

• Satisfactory expansion was achieved in 16 out of 21 patients using 27 expanders.
• Complications occurred in 13 patients, including 6 major (e.g., infection, wound dehiscence, leakage) and 11 minor events.
• No flap necrosis was observed; infections were managed by expander removal, and hematomas were evacuated.

Conclusions:

• Tissue expanders can yield satisfactory results in burn scar reconstruction, but treatment involves substantial effort and potential complications.
• Meticulous adherence to indications and surgical experience are vital for minimizing major complications.
• Strategies such as early hematoma evacuation, using larger valves to prevent leakage, and small incisions can improve outcomes.
