Objective: To review the research progress of the principle and clinical application of keloid core excision technique.
Methods: The literature on keloid core excision technique at home and abroad in recent years was extensively reviewed, and the principle, development history, indications, advantages and disadvantages of this technique were summarized, and the existing controversies were analyzed.
Results: Keloid core excision is a technique to remove the inner fibrous core from the keloid and cover the defect with the keloidal flap. It reduces the wound tension, yields good aesthetic results in the treatment of ear keloids, and reduces the recurrence rate of keloids combining with adjuvant therapies.
Conclusion: The keloid core excision technique has specific advantages, yet its overall efficacy remains controversial. Further studies are imperative to explore the mechanisms regarding keloid recurrence and the vascular supply principles of the keloidal flap. It is also necessary to define appropriate surgical indications and safety protocols of this technique.
目的: 综述瘢痕疙瘩核心切除技术的原理及应用研究进展。.
方法: 广泛查阅近年国内外有关瘢痕疙瘩核心切除技术的文献，对该技术的原理、发展历史、适应证、优缺点等进行总结，并分析目前存在的争议。.
结果: 瘢痕疙瘩核心切除技术是一种通过切除瘢痕疙瘩增殖活跃的纤维核心、保留瘢痕瓣覆盖缺损的手术方式，可以降低切口缝合张力，用于耳部瘢痕疙瘩治疗时可以获得良好的形态效果，联合辅助治疗可以减少瘢痕疙瘩复发。.
结论: 瘢痕疙瘩核心切除技术存在一定优势，但目前对其效果尚存在争议，未来仍需开展更多研究进一步探索瘢痕疙瘩的复发机制和瘢痕瓣的血运规律，以进一步明确手术适应证及保证安全实施该技术。.
