Tissue expansion: A simple technique for complex traumatic soft tissue defects

Area of Science:

• Plastic Surgery
• Regenerative Medicine

Background:

• Post-traumatic soft tissue loss presents significant functional and esthetic challenges.
• Reconstruction is often hindered by a lack of suitable autogenous tissue.
• Tissue expansion offers a method to generate well-matched, sensate autogenous tissue for reconstruction.

Observation:

• Fifteen patients (7-43 years) with large post-traumatic defects (burns, avulsions, abdominal wall, elbow, neck) underwent tissue expansion over 22 months.
• Indications included facial post-burn scars, post-burn alopecia, scalp avulsion, abdominal wall defects, elbow ankylosis, and neck contractures.
• The procedure was generally well-tolerated, with minor complications in 20% and major complications (implant deflation/exposure) in 6.6% of cases.

Findings:

• Tissue expansion successfully managed diverse and complex soft tissue defects.
• The technique provided esthetic and functional restoration through autogenous tissue generation.
• Excellent reconstructive results were achieved despite the slow, staged nature of the procedure.

Implications:

• Tissue expansion is a safe and viable reconstructive option for extensive post-traumatic soft tissue defects.
• It enables the creation of matched, sensate tissue, improving functional and esthetic outcomes.
• This method addresses the limitations of tissue scarcity in reconstructive surgery.
