What is a muscle flap?

by

A muscle flap is a muscle which is transplanted to cover a defect while maintaining its original blood supply. So, if there is defect in tissue after surgical excision, a muscle is mobilized to cover the defect, and thus it is called a muscle flap.

For example, abdominal muscle is used as a flap and transferred to the breast area after the breast is removed for cancer.

Chest muscle is sometimes mobilized and placed in the chest cavity if an abscess is drained from the chest. This procedure is done by chest surgeons.

Muscle flaps are used by reconstructive plastic surgeons to cover or repair tissue defects in almost every part of the body.
