Objective To review the researches of donor nerve’s promoting effect on regeneration of reci pient nerve in end-to-side neurorrhaphy at home and abroad. Methods The latest original l iterature concerning donor nerve’s accelerating effect on regeneration of recipient nerve was extensively reviewed. Results Proper nerve cutting may promote nerve regeneration. But how to quantize the cutting volumn was still a challenge. Conclusion It is important to research thedonor nerve in neurorrhaphy, which can provide evidence for cl inical neurorrhaphy so as to achieve good results.
