Reconstruction of a full-thickness upper third defect of the helix ear using a single-stage chondrocutaneous composite transposition flap

摘要

The external ear is a crucial part of the ear's anatomy for both functional and aesthetic purposes. We present a defect after the extirpation of an invasive squamous cell carcinoma, where the final defect involved the superior third of the outer ear, missing both cartilage and skin. The regional chondrocutaneous composite transposition flap of the ipsilateral auricular concha is a one-stage technique that successfully preserves the helical rim's shape and size.
