Reconstructing the Post-Burn Auricle: A Microsurgical Approach Using a Contralateral Free Temporoparietal Fascial...

Post-burn auricular defects compromise both aesthetics and facial symmetry, often imposing significant social and psychological burdens that severely diminish patients' quality of life. Scarring in the mastoid region following burns typically exhibits poor elasticity and texture, along with compromised cutaneous blood supply. Scar contracture further leads to displacement and deformation. These factors collectively contribute to the considerable complexity and variability inherent in post-burn auricular reconstruction. The intricate three-dimensional structure of the auricle itself renders its restoration a formidable challenge in plastic and reconstructive surgery. In this study, we present a single-stage reconstruction strategy for post-burn ear deformity applicable when local skin is unsuitable and the ipsilateral temporoparietal fascia is non-viable. The technique involves framework fabrication using autologous costal cartilage, followed by coverage with a contralateral free temporoparietal fascial flap. We propose that this approach offers a valuable and effective option for auricular reconstruction in such complex scenarios.
