Objective: In order to provide experimental foundation for replantation in the recurrent laryngeal nerve(RLM) of the laryngeal reconstruction and laryngeal transplantation.
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 process in regeneration of the RLN were observeded 1 week (two dogs), 2 week (two dogs) and 4 week (two dogs) after the replantation.
Result: The replantation of RLN of six dogs succeeded.
Conclusion: The results confirmed that sewing up the cut RLN at once is helpful to get normal regeneration in the replantation.
