A multifaceted approach for traumatic auricular avulsion with venous congestion

Choice of operative technique is often a major factor in the success of replantation of traumatic avulsions of the auricle. While microsurgery is considered to produce the best aesthetic results, this approach may not be an option due to vascular damage. We present the case of a 66-year-old Caucasian male with a subtotal traumatic left auricle avulsion. Microsurgical repair was not attempted as vessels amenable to anastomosis could not be found. Instead, the auricle was replanted in a non-microsurgical manner as a composite graft using Monocryl sutures. As a preventative measure for clot formation heparin was injected intradermally throughout the anterior auricular surface and helix. Twenty-four hours postoperatively, as signs of venous congestion were noted, a multimodal therapy was initiated combining mechanical, chemical and biological therapies. Medicinal leech therapy (hirudotherapy) was used to enhance venous drainage and prevent clot formation. Hirudotherapy is an effective and safe treatment modality for venous outflow obstruction in avulsed auricle injuries. However, one must consider the possible complications of leech therapy and the need for close monitoring. An examination conducted two months following the initial injury revealed optimal patient outcomes with excellent aesthetic results and full auricular sensation. Good vascular outflow is integral to the successful salvage of replanted tissues. Venous stasis must be identified and addressed early for good patient outcomes. The current report highlights the importance of a multifaceted approach in cases of traumatic auricular avulsions followed by venous congestion.
