狗喉返神经再植动态观察

Observation on the kinetic process in replantation of the recurrent laryngeal nerve of the dog

目的 :为喉重建、喉移植中喉返神经再植提供实验依据。方法 :择杂种狗 10只 ,切断左侧喉返神经 ,观察切断神经后即刻 (2只 ) ,3.5 h(2只 )组织病理学结构。 6只即刻行喉返神经端端显微缝合再植。于术后 1周(2只 )、2周 (2只 )、4周 (2只 ) ,观察神经端端缝合再生动态与组织学结构。结果 :于喉返神经切断即刻缝合的 6只狗 ,喉返神经均再植成功。结论 :喉返神经切断后即刻缝合 ,其修复再生能力正常。

Objective:In order to provide experimental foundation for replantation in the recurrent laryngeal nerve(RLM) of the laryngeal reconstruction and laryngeal transplantion.Method:The left RLN of ten caine dogs were cut.The histopathology of the cut RLN were observed under the microscope after operation (two dogs)and 3.5 hours later (two dogs).Meanwhile the RLN were sewed up under the microscope at once.The kinetic procss in regeneration of the RLN were observedon 1 week (two dogs),2 week (two dogs)and 4 week (two dogs) after the replantation.Result:The replantation of RLN of six dogs succeded.Conclusion:the results confirmed that sewing up the cut RLN at once is helpful to get normal regeneration in the replantation.
