The lateral genicervical flap, a facial subdermal vascular network flap (SVNF), offers a successful alternative for facial reconstruction. Its viability relies on the subdermal vascular network and arterial anastomoses, minimizing donor-site morbidity.

Area of Science:

  • Plastic Surgery
  • Anatomy
  • Microsurgery

Background:

  • Facial reconstruction demands ideal flaps with good color match and minimal donor-site morbidity.
  • The lateral genicervical flap, a type of facial subdermal vascular network flap (SVNF), has shown promise in recent clinical applications.

Observation:

  • Anatomical study of 14 cadaver dissections detailed the facial subdermal vascular network (SVNF).
  • Facial skin receives blood supply from facial, superficial temporal, and infraorbital arteries.
  • The lateral genicervical region is supplied by facial, superficial temporal, occipital, and superior thyroid arteries, forming a subdermal arterial network.

Findings:

  • The SVNF features a honeycomb-like anastomotic structure in the corium.
  • The flap's pedicle blood supply originates from perforator branches forming the subdermal vascular network.

  • Anastomoses between facial and superficial temporal arteries in the lateral genicervical region provide a robust vascular basis for the flap.

    • Implications:

    • The lateral genicervical flap is a viable alternative for facial defect reconstruction, particularly for superficial temporal defects.
    • Understanding the vascular network's directivity is crucial for successful clinical application of this flap.
    • This flap offers potential for improved outcomes in reconstructive surgery with reduced donor-site morbidity.
