    Area of Science:

    • Plastic Surgery
    • Reconstructive Surgery
    • Microsurgery

    Background:

    • Soft tissue defects necessitate reconstructive techniques, with perforator-based flaps offering significant advantages.
    • The ulnar forearm flap, a type of septocutaneous flap, utilizes perforators from the ulnar artery for its vascular supply.

    Observation:

    • The ulnar forearm flap provides thin, pliable skin with a consistently large and reliable vascular pedicle.
    • This flap can be combined with underlying muscles, nerves (sensory or motor), and even a segment of the ulna.
    • Unlike the radial forearm flap, it avoids flexor tendon exposure, facilitating successful skin grafting.

    Findings:

    • The ulnar forearm flap was successfully utilized in two patients requiring soft tissue coverage.
    • Advantages include a thin, pliable skin paddle, a constant and large pedicle, and versatility in reconstruction.

  • The donor site scar is cosmetically favorable due to its forearm location, aiding skin graft take.

    • Implications:

    • The ulnar forearm flap is well-suited for covering thin defects requiring mobility, such as in the extremities or intraoral region.
    • It can be employed as a distally or proximally based island flap for hand or arm defect coverage, respectively.
    • This flap presents a valuable alternative to other forearm flaps, offering distinct benefits in specific reconstructive scenarios.
