Partial Avulsion

Partial Avulsion

Description : The auricle may be partially avulsed during an automobile accident or industrial mishap. The blood supply to the auricle is excellent and its metabolic demands are relatively low; therefore, primary reattachment is frequently successful, even with a tenuous pedicle.

Management of these injuries consists of an early meticulous reimplantation, with minimal debridement and the use of low-dose heparin sodium to prevent thrombosis, appropriate antibiotic coverage to prevent infection, and multiple stab incisions to relieve venous congestion while revascularization is taking place.

Several case reports have demonstrated the survival of completely avulsed auricles following prompt and careful reattachment.

The superior half of this ear was torn away when the patient fell against a concrete wall.
