Pectoralis major myocutaneous flaps in rats

Area of Science:

• Regenerative Medicine
• Surgical Innovation
• Animal Models

Background:

• Muscle degeneration and skin changes are critical concerns in reconstructive surgery.
• Existing animal models may not fully capture the complexities of flap viability.
• Neurovascular island flaps offer potential for improved tissue survival.

Purpose of the Study:

• To establish a novel neurovascular, island, myocutaneous flap model in rats.
• To evaluate the utility of this model for studying ischemia and denervation effects.
• To assess the reliability of flap elevation for potential free flap transfer.

Main Methods:

• Creation of a new neurovascular island myocutaneous flap incorporating the pectoralis major muscle in a rat model.
• Inclusion of a delay procedure to enhance flap viability.
• Surgical technique focused on reliable flap elevation.

Main Results:

• The developed rat model allows for the observation of muscle degeneration.
• The model facilitates the study of skin changes induced by ischemia or denervation.
• The flap can be reliably raised, suitable for use as a free myocutaneous flap.

Conclusions:

• A new neurovascular island myocutaneous flap model has been successfully created in rats.
• This model is valuable for investigating the pathophysiology of ischemia and denervation in muscle and skin.
• The reliable elevation of this flap supports its application in further reconstructive surgery research.
