Abstract Category: General Reconstruction
The goal of auricular reconstruction should focus on preserving function, maintaining the contour and shape of the helical rim, and restoring three-dimensional form and cartilaginous support. In this case report, a 56 year-old-woman presents after basal cell carcinoma Mohs resection involving the upper third of her ear, including the superior helix, crura of antihelix, triangular fossa, and crus of helix as well as temporal scalp and lateral cheek. To reconstruct the defect involving multiple cosmetic subunits, a combination approach was taken using a conchal bowl chondrocutaneous transposition flap, cheek advancement flap, and full-thickness skin graft to restore form and function to the ear. The conchal bowl flap is based on the direct auricular branch of the superficial temporal artery and its benefits include robust blood supply, single-stage reconstruction, composite nature of flap, ipsilateral ear donor site as well as suitable shape and curvature to restore the root of the helix as well as the superior helix.
