随着“腹壁核心健康”概念的提出，对于各种类型的复杂腹壁疝，需要采用不同的外科技术进行个体化的功能性腹壁重建。腹壁重建的精细化实施需要对腹壁肌筋膜的血管、神经和腹壁生物力学的深度认知。腹外斜肌肌瓣是一种新型腹壁重建技术，其在缺损附近制备肌瓣，保留了较完整的肌瓣神经支配和血管供应，适用于特殊类型（如腹直肌复合体缺失）、特殊部位（半月线部位大或巨大切口疝）、特定状态（侧腹壁疝合并腹腔失容、创伤性侧腹壁破裂伴污染）腹壁缺损的功能性重建。该技术无需血管、神经吻合，操作较便捷，易于掌握并应用于临床。

With the introduction of the concept of “abdominal core health”, various kinds of complex abdominal wall hernias require individualized functional abdominal wall reconstruction using different surgical techniques. Precise abdominal wall reconstruction requires a deep understanding of the blood vessels, nerves, and biomechanics of the abdominal wall fascia. The external oblique muscle flap is a novel type of abdominal wall reconstruction technique, which is preformed near the defect, preserves relatively complete muscle flap nerve innervation and vascular supply, and is suitable for special types (such as absence of rectus abdominis complex), special sites (large or giant semilunar line incisional hernia), specific conditions (lateral ventral hernia with loss of domain, traumatic ventral hernia with contamination) of functional reconstruction of abdominal wall defects. This technique requires no vascular or nerve anastomosis, features convenient operation, is easy to master, and possesses good clinical applicability
