本研究进行了CO_2激光吻合周围神经的动物实验,21只大老鼠作实验动物,每只鼠的两条坐骨神经分成两组,每组共21条神经。左侧组的神经离断后采用激光“焊接”吻合方法;右侧组的神经离断后采用缝合吻合。60天后进行结果测定,根据术后神经电生理测试和形态学检验的结果得出的结论是:激光吻合神经具有操作简单省时的特点;对神经组织损伤小,较少遗留异物反应,有利神经的再生。电生理测试结果未见两种方法吻合的神经电活动有明显的差异。在上述实验的基础上,我们对一名面神经外伤离断的患者进行了激光吻合治疗,收到了满意疗效。
In this study, animal experiments of CO2 laser anastomosing peripheral nerves were performed. Twenty-one rats were used as experimental animals. The two sciatic nerves of each rat were divided into two groups, each with 21 nerves. The left side of the group of nerves after the use of laser “welding” anastomosis; the right group of nerves after the use of stitching anastomosis. 60 days after the results were measured, according to postoperative neuroelectrophysiological test and morphological test results concluded that: laser anastomosis has the advantages of simple and time-saving features; small damage to the nerve tissue, less residual foreign body reaction, favorable nerve The regeneration. Electrophysiological test results showed no significant difference between the two methods of neuroelectrical activity. Based on the above experiments, we performed a laser anastomosis on a patient with facial nerve trauma and received satisfactory results.
