  • Title: Bilobed flap for reconstruction of defects of the helical rim and posterior ear.
    Author: Vergilis-Kalner IJ, Goldberg LH.
    Journal: Dermatol Online J; 2010 Oct 15; 16(10):9. PubMed ID: 21062603.
    Abstract:
    When contemplating the repair of defects involving the ear, second intention healing and full or split thickness skin grafts are often considered for reconstructive choices. Closing the combined full thickness helical rim and posterior ear defects, however, represents a reconstructive challenge because of the lack of available freely mobile skin anteriorly, superiorly, and inferiorly to the defect. The choice of the bilobed flap circumvents this challenge by rotating the skin and recruiting the tissue from the post-auricular sulcus, the lower pole of the posterior ear, and, if necessary, from the superior area of the neck adjacent to the posterior ear. This bilobed flap also enables an inconspicuous closure of the donor site and provides sufficient blood supply to ensure flap viability in a simple one-stage repair. Herein, we describe two cases in which we used the bilobed flap to rotate skin from the post-auricular surface to reconstruct full thickness skin defects involving the helical rim and posterior ear, with excellent cosmetic results.
