[Skin substitutes in chronic wounds]

Area of Science:

• Regenerative Medicine
• Wound Healing
• Biomaterials

Background:

• Chronic wounds present a significant challenge in healthcare due to impaired dermal and epidermal repair mechanisms.
• Traditional grafting methods like split-skin, Reverdin, and pinch grafts can achieve wound closure but often suffer from low take rates.
• The demand for effective skin substitutes is high to address the limitations of current treatments for chronic wound management.

Purpose of the Study:

• To review the current landscape and future potential of skin substitutes in managing chronic wounds.
• To highlight advancements in skin substitute technologies and their impact on wound healing outcomes.
• To discuss the clinical application and emerging trends in skin regeneration for complex wound defects.

Main Methods:

• Review of existing literature on skin substitutes and wound closure techniques.
• Analysis of clinical outcomes for various grafting and skin substitute applications.
• Exploration of novel approaches including cell-based therapies and genetic modifications for enhanced skin regeneration.

Main Results:

• Combined mesh-grafting and vacuum-sealing techniques show improved graft healing and wound closure rates.
• Autologous keratinocyte transplantation offers a viable option for skin reconstruction, with initial positive clinical results.
• Temporary and permanent skin substitutes broaden the therapeutic spectrum for chronic wound defect coverage.

Conclusions:

• Skin substitutes, including keratinocyte sheets and cell suspensions, are vital for chronic wound management.
• Advancements in grafting techniques and the development of novel skin substitutes are crucial for improving patient outcomes.
• Future directions in genetic therapy hold significant promise for the next generation of skin substitutes in regenerative medicine.
