Interpolation flaps are a two-stage surgical technique for reconstructing large defects using vascularized tissue. This method is effective for nose and ear reconstruction, offering bulk and survival on exposed structures.

Area of Science:

  • Plastic Surgery
  • Reconstructive Surgery
  • Dermatologic Surgery

Background:

  • Large or deep defects often lack sufficient local tissue for direct repair.
  • Adjacent tissue limitations necessitate the use of non-local donor tissue.
  • Reconstruction requires methods that can provide bulk and survive compromised wound beds.

Purpose of the Study:

  • To describe the utility of interpolation flaps in reconstructive surgery.
  • To highlight three specific interpolation flaps for head and neck reconstruction.
  • To provide dermatologic surgeons with effective options for complex defects.

Main Methods:

  • Utilizing interpolation flaps with an intact vascular pedicle to bridge nonadjacent donor and recipient sites.
  • Employing a two-stage surgical approach: initial flap transfer and delayed pedicle division.

  • Assessing flap survival based on neovascularization and inosculation with the recipient bed.
  • Main Results:

    • Interpolation flaps can supply significant thickness and bulk for large or deep defects.
    • Flaps demonstrated viability even when placed over exposed bone or cartilage.
    • Successful application in the reconstruction of nasal and auricular defects was observed.

    Conclusions:

    • Forehead, melolabial, and postauricular interpolation flaps are valuable reconstructive tools.
    • These flaps offer a reliable solution for defects where local tissue is inadequate.
    • Interpolation flaps expand the reconstructive armamentarium for complex facial defects.
