Moist heat postconditioning to increase flap survival.

Area of Science:

• Reconstructive Microsurgery
• Tissue Engineering
• Wound Healing

Background:

• Improving skin flap survival is crucial in reconstructive microsurgery.
• Current methods for enhancing tissue viability have limitations.

Purpose of the Study:

• To introduce and evaluate moist heat postconditioning as a method to increase skin flap survival.
• To assess the effectiveness of this noninvasive technique.

Main Methods:

• Truncal flaps were elevated in eight New Zealand rabbits.
• Moist heat was applied for 30 minutes to the flaps in the trial group post-inset.
• Flap survival ratios were calculated after 2 weeks using ImageTool software.

Main Results:

• Flaps treated with moist heat showed a significantly lower average necrosis ratio (4.91%) compared to the control group (37.31%).
• The difference in survival rates was statistically significant (p = 0.000).

Conclusions:

• Moderate moist heat applied post-flap inset significantly increases skin flap survival.
• This method is noninvasive, cost-effective, and safe for potential clinical application.
