A Newly Defined Conchal Floor Arterial Flap for Auricular Reconstruction.

Park, Chul M.D.

: A conchal floor composite flap pedicled by skin of the helical crus has been well described in the literature. Here the flap is elevated based on the supply by an upper auricular branch of the superficial temporal artery. In this article, a newly defined conchal floor arterial flap is proposed. The flap is based on the main stem of the posterior auricular artery and its venae comitantes. Two types of conchal floor arterial flaps were elevated: a proximally based chondral arterial flap and a distally based chondrocutaneous arterial flap. The proximally based flap was used for earlobe reconstruction, whereas the distally based flap was useful in the reconstruction of the upper auricle. Nine congenital auricular malformations were successfully corrected with this newly defined conchal floor flap procedure. This type of flap is easier to elevate, more reliable, and more versatile than the one currently in use.
