Area of Science:

  • Anatomy
  • Vascular Surgery
  • Reconstructive Surgery

Background:

  • The auriculomastoid region's vascular supply is crucial for reconstructive procedures.
  • Understanding the reliability of the posterior auricular vessels is essential for flap viability.

Purpose of the Study:

  • To investigate the detailed blood supply of the auriculomastoid skin.
  • To establish the dependability of posterior auricular vessels for skin flap viability in this area.

Main Methods:

  • Arteriograms and cadaver dissections were performed.
  • India ink perfusion, lead oxide injection, and contact radiography were utilized.
  • Operative dissections and clinical flap transfers provided additional data.

Main Results:

  • Detailed vascular mapping of the auriculomastoid skin was achieved.
  • The posterior auricular vessels were confirmed as a reliable source for flap elevation.
  • Successful clinical transfers demonstrated the practical application.

Conclusions:

  • Auriculomastoid skin can be safely transferred using posterior auricular vessels.
  • This vascular supply supports both island and free flap techniques.
  • The findings support the use of these flaps in reconstructive surgery.
