Microsurgical grafting of a free flap is an established technique of surgical reconstruction. The forearm free flap is frequently used following removal of oral and/or pharyngeal tumors. However, simple split-thickness skin grafting on full-thickness defects of the skin on the flexor side of the forearm results in deformations, pigmentation, and the adhesion of the graft to the tendons. The authors attempted to minimize such problems by repairing the flap donor site with a collagen sponge used as an artificial dermis. This artificial dermis was used to reconstruct postoperative defects in the skin of 5 patients. Split-thickness skin measuring 0.25 to 0.30 mm was grafted onto the defect. The donor site skin was successfully repaired in 2 to 3 weeks without adverse effects, without the development of depressed deformations, and with only slight pigmentation. The artificial dermis formed a matrix on the donor wound bed, with good cosmetic results.
游离皮瓣显微外科移植是一种成熟的手术重建技术。前臂游离皮瓣常用于口腔和/或咽部肿瘤切除术后。然而，在前臂屈侧皮肤全层缺损处单纯进行中厚皮片移植会导致畸形、色素沉着以及皮片与肌腱粘连。作者试图通过使用胶原海绵作为人工真皮修复皮瓣供区来尽量减少此类问题。这种人工真皮用于重建5例患者术后的皮肤缺损。将厚度为0.25至0.30毫米的中厚皮片移植到缺损处。供区皮肤在2至3周内成功修复，无不良反应，未出现凹陷性畸形，仅有轻微色素沉着。人工真皮在供区创面形成了一个基质，美容效果良好。
