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.
手术技术的选择往往是外伤性耳廓撕脱再植成功的主要因素。虽然显微外科手术被认为能产生最佳美学效果,但由于血管损伤,这种方法可能不是一个选择。我们报告一例66岁白人男性左耳廓大部分外伤性撕脱的病例。由于未找到适合吻合的血管,未尝试显微外科修复。取而代之的是,将耳廓作为复合移植物以非显微外科方式重新植入,使用了聚乙醇酸缝线。作为预防血栓形成的措施,在前耳廓表面和耳轮全程皮内注射肝素。术后24小时,由于发现静脉充血迹象,开始了机械、化学和生物疗法相结合的多模式治疗。使用医用水蛭疗法(水蛭疗法)来增强静脉引流并防止血栓形成。水蛭疗法是治疗耳廓撕脱伤静脉流出道梗阻的一种有效且安全的治疗方式。然而,必须考虑水蛭疗法可能的并发症以及密切监测的必要性。初次受伤两个月后的检查显示患者预后良好,美学效果极佳,耳廓感觉完全恢复。良好的血管流出对于成功挽救再植组织至关重要。为了获得良好的患者预后,必须尽早识别并处理静脉淤滞。本报告强调了在外伤性耳廓撕脱伴静脉充血病例中采用多方面方法的重要性。
