Free microvascular greater omentum flap to pad brachial plexus after neurolysis for actinic lesions is a major operation. Thus several authors have suggested a simple padding by means of traditional muscle flaps. As contouring the brachial plexus elements is difficult using muscle, we wished to evaluate the formation of perineural fibrosis with either omentum or muscle, following neurolysis. An experimental model in rats was set up, dividing the two femoral nerves and wrapping one of them with the greater omentum and the other with abdominal muscles. The degree of perineural fibrosis at light microscopy observation was fivefold greater when muscle, rather than omentum, was used.
对于光化性损伤行神经松解术后，采用游离微血管大网膜瓣填充臂丛神经是一项大手术。因此，几位作者建议用传统肌瓣进行简单填充。由于使用肌肉对臂丛神经各成分进行塑形很困难，我们希望评估神经松解术后用大网膜或肌肉填充时神经周围纤维化的形成情况。建立了大鼠实验模型，将两条股神经分开，一条用大网膜包裹，另一条用腹肌包裹。在光学显微镜观察下，使用肌肉时神经周围纤维化程度比使用大网膜时高五倍。
