Abstract
Reconstructive oral and maxillofacial surgeons often find the need for additional soft tissue even when a myocutaneous flap has been previously placed. This article introduces the principles, technique, and results of 32 “walk-up” muscle flaps derived from existing myocutaneous flaps. The anastomotic vascular ingrowth at the original myocutaneous flap's distal end permits its proximal detachment and axial vessel ligation to rotate the proximal two thirds to a tissue-deficient site. In our experience at the University of Miami, these flaps have been predictable (97% viable transfer rate), have provided vascular soft tissue in deficient areas, and have been skin grafted at their surface to increase oral lining or skin cover, among several other uses.
