Extended V-Y Advancement Flap Reconstruction of a Large Posterior Upper Midline Trunk Defect.

Large posterior upper trunk defects can be challenging to reconstruct. Trapezius or latissimus dorsi myocutaneous flaps are principally utilized for reconstruction; however, some defects may not be amenable to this standard approach. Here, we describe a patient with a full-thickness skin and subcutaneous tissue loss of the upper back and inferior cervical region after dermatofibrosarcoma protuberans resection. A large, extended V-Y flap was used for closure of this wound secondary to its location, size, and orientation. This approach preserves shoulder function, allows for readvancement of the flap as needed, and is a reconstructive option for patients with large upper back defects.
