Abstract

Purpose of review: Auricular avulsion injuries present complex reconstructive challenges due to the intricate three-dimensional (3D) structure and vascular supply of the ear. This review examines traditional and emerging techniques in auricular trauma repair, including microsurgical advancements, digital planning, tissue engineering, and 3D bioprinting, highlighting their impact on reconstructive outcomes.

Recent findings: Traditional techniques, such as multilayer closure and microsurgical reattachment, remain foundational in auricular reconstruction. However, recent studies suggest that subtotal amputations with small vascular pedicles may survive without microvascular anastomosis. Microsurgical refinements, including digital planning and customized surgical guides, enhance precision in reconstruction. Tissue engineering innovations, such as 3D bioprinting with biomimetic scaffolds and magnetoresponsive hydrogels, show promise for auricular cartilage regeneration. Additionally, postoperative adjuncts like antipressure alarm systems and bioactive hydrogels seeded with stem cells improve healing and long-term outcomes.

Summary: Auricular trauma repair is evolving through a combination of established and innovative techniques. Digital planning, microsurgical advancements, and tissue engineering are shaping a new era of patient-specific reconstruction. Future research should focus on refining these technologies, evaluating long-term efficacy, and addressing economic feasibility to optimize patient outcomes.

外伤性耳廓撕脱伤的处理-部分和完全。

综述目的：由于耳部复杂的三维结构和血管供应，耳部撕脱伤的重建面临复杂的挑战。本文综述了耳部创伤修复的传统技术和新兴技术，包括显微外科手术的进步、数字计划、组织工程和3D生物打印，并强调了它们对重建结果的影响。近年来的研究发现：传统技术，如多层封闭和显微外科再植，仍然是耳廓重建的基础。然而，最近的研究表明，小血管蒂的次全截肢可以在没有微血管吻合的情况下存活。显微外科技术的改进，包括数字化规划和定制手术指南，提高了重建的精度。组织工程方面的创新，如生物3D打印仿生支架和磁响应水凝胶，显示了耳软骨再生的前景。此外，术后辅助装置，如抗压报警系统和植入干细胞的生物活性水凝胶，可以改善愈合和长期疗效。摘要：耳廓创伤修复是通过既有技术和创新技术的结合而不断发展的。数字规划、显微外科手术的进步和组织工程正在塑造一个针对患者的重建的新时代。未来的研究应侧重于改进这些技术，评估长期疗效，并解决经济可行性，以优化患者的结果。
