A method is described where the planned directional undermining of a subcutaneous triangular flap creates a long pedicle and in the process the flap is "unfolded" to increase its advancement. The flap can be undermined and advanced without any tension. This method is recommended where more conservative undermining is inadequate for mobilisation, particularly in larger defects and in the replacement of skin defects on the lower eyelid which needs to support the eyelid. This technique depends on the richness of the random blood supply in the head and neck regions and the availability of adequate depth of subcutaneous tissue for the development of a long pedicle. Using this method in 53 cases, it has been found possible to advance the flap way past the defect if so desired. Some minor disadvantages of this flap are also described.
本文描述了一种方法，即通过对皮下三角形皮瓣进行计划性的定向潜行分离来形成一个长蒂，在此过程中皮瓣被“展开”以增加其推进距离。皮瓣可以在无任何张力的情况下进行潜行分离和推进。当更保守的潜行分离不足以实现皮瓣移动时，尤其在较大缺损以及需要支撑眼睑的下眼睑皮肤缺损修复中，推荐使用此方法。该技术依赖于头颈部区域随机血供的丰富程度以及有足够深度的皮下组织以形成长蒂。在53例病例中使用此方法发现，如果有需要，可以将皮瓣推进至远超缺损处。文中还描述了该皮瓣的一些小缺点。
