Failed tissue expansion in a patient with osteogenesis imperfecta

Area of Science:

• Plastic Surgery
• Dermatology
• Regenerative Medicine

Background:

• Tissue expansion is a common reconstructive technique.
• It relies on the skin's ability to stretch and adapt.
• Underlying conditions can affect tissue response.

Observation:

• A 43-year-old patient with mild osteogenesis imperfecta tarda experienced tissue expander failure.
• The expander could not be filled with saline.
• Skin histology was performed on the affected tissue.

Findings:

• Histological examination revealed thrombosis and necrosis of blood vessels within the skin.
• These findings suggest compromised vascular integrity.
• The failure was attributed to the patient's reduced skin proliferative potential.

Implications:

• This case challenges the sole reliance on mechanical skin laxity for successful tissue expansion.
• It highlights the critical role of cellular proliferation and vascular health.
• Further research is needed to understand patient-specific factors influencing tissue expansion outcomes.
