The rhomboid flap is a reliable, versatile, and widely used tool in head and neck surgery. Although its geometry is well described, the mechanics of the flap have not been scientifically investigated. For example, there is disagreement whether the maximum tension is located at the closure of the donor site or at the tip of the flap. An experimental model using piglets and stabilized force gauges has been developed to measure the distribution of tension in a standard Limberg flap (60 degrees rhomboid). Variables evaluated include the size of the rhomboid, the amount of undermining, and the position of the flap on the animal. Consistent measurements show tension at the closure of the donor site to represent the majority of tension around the flap (58% average); the size of the rhomboid and degree of undermining do not change relative tensions. A composite figure discloses the relationship of the initially outlined flap to the final result and quantifies the observable changes in the length of sides.
菱形皮瓣是头颈外科中一种可靠、通用且广泛应用的工具。尽管其几何形状已有详细描述，但皮瓣的力学原理尚未得到科学研究。例如，对于最大张力是位于供区闭合处还是皮瓣尖端存在分歧。已开发出一种使用仔猪和稳定测力计的实验模型，以测量标准林贝格皮瓣（60度菱形）中的张力分布。评估的变量包括菱形的大小、潜行分离的程度以及皮瓣在动物身上的位置。一致的测量结果表明，供区闭合处的张力占皮瓣周围张力的大部分（平均58%）；菱形的大小和潜行分离的程度不会改变相对张力。一个复合图形揭示了最初勾勒的皮瓣与最终结果之间的关系，并量化了边长度的可观察变化。
