Auricular Reconstruction and Injury Management

Auricular reconstruction and injury management encompass a multidisciplinary approach to restoring form and function following partial or complete loss of the external ear. The auricle’s intricate cartilage framework and delicate skin envelope pose significant challenges, particularly when injury results from trauma, burns, congenital anomalies or oncological resection. Initial management focuses on meticulous wound debridement, haemostasis and preservation of viable tissue. Microsurgical techniques enable replantation of avulsed segments through arterial and venous anastomoses, often supplemented by medicinal leech therapy to manage venous congestion. When replantation is not feasible, autologous costal cartilage grafts fashioned into anatomically precise frameworks and covered by local or regional flaps remain the gold-standard for durable reconstruction. Composite grafts and hyperbaric oxygen therapy can enhance outcomes in small defects, while emerging strategies, including three-dimensional bioprinting of patient-specific scaffolds and bioengineered cartilage, promise personalised solutions. Psychological support and long-term rehabilitation are integral, given the profound aesthetic and psychosocial impact of auricular defects. Global disparities in resources have driven innovation in simplified one-stage procedures that maintain high aesthetic standards in low-resource settings.

Auricular Reconstruction and Injury Management publication trend

The graph below shows the total number of articles in auricular reconstruction and injury management across all publications each year (not limited to Nature Index journals).

Technical terms

Auricular avulsion: Traumatic detachment of the external ear from its anatomical base, often requiring replantation or reconstruction.

Composite graft: A free tissue transfer comprising skin and cartilage or other tissues without microvascular anastomosis, used for small-scale auricular defects.

Perforator flap: A local or regional flap based on isolated skin perforators supplying blood to the flap, minimising donor-site morbidity.

Chondrocutaneous advancement flap: A technique that advances a composite block of cartilage and overlying skin into a defect, preserving structural continuity.

Microvascular replantation: Surgical reattachment of an amputated ear segment by anastomosing its arteries and veins under microscopy.

Three-dimensional bioprinted scaffold: A custom-designed framework produced by additive manufacturing, seeded with cells to regenerate auricular cartilage.
