下腹直肌皮瓣的制备及其应用解剖学研究

目的了解腹壁下动脉的走行及其与腹直肌的关系，为临床使用下腹直肌皮瓣修复口腔颌面部缺损提供理论依据。方法利用10具经10％甲醛溶液固定的中国人成人标本，模拟手术方法制备下腹直肌皮瓣，同时对腹直肌及腹壁下动脉进行解剖观察并摄像，用图像分析软件进行测量。结果腹壁下动脉的起始外径为（2.58±0.60）mm，主干长度为（85.87±14.90）mm，穿支血管向脐周方向集中。结论腹壁下动脉走行恒定，起始外径较粗，下腹直肌肌皮瓣和穿支皮瓣均较适合用于口腔颌面部缺损修复。

The design of inferior rectus abdominis flap and its study of applied anatomy

Objective To describe the anatomy of inferior epigastric artery and its correlation with rectus abdominis muscle in order to provide anatomical basis for reconstruction of defect in the oral and maxillofacial region. Methods 10 Chinese adult specimens fixed by 10% formalin were simulated for the design of inferior rectus abdominis flap, and then observing, taking a photograph during the cadavers were being operated and measuring by image analysis software in the end. Results The original external diameters of inferior epigastric artery and length of its trunk were （2.58±0.60）mm and （85.87±14.90）mm respectively. Its perforators distribute intensively toward hilum. Conclusion Whether rectus abdominis myocutaneous flap or deep inferior epigastric perforator flap adapts to reconstruct the defect of oral and maxillofacial region due to invariable traveling of inferior epigastric artery and its wide original external diameters relatively.
