Abstract

INTRODUCTION

In this experimental study, we aimed to observe the improvement of vocal cord function in rabbits after iatrogenic transection of the recurrent laryngeal nerve with subsequent inter-recurrent free nerve graft transposition.

METHODS

The study consisted of 2 groups (the experimental group and the control group) each containing 8 rabbits. The right recurrent nerve was transected both in the control and experiment groups. Inter-recurrent free nerve graft transposition using sural nerve was performed with end-to-side anastomosis in the experimental group whereas in the control group, nerve reconstruction was not done.

RESULTS

After the 3rd postoperative month, the right vocal cord activity was recorded in the experimental group using videolaryngoscopy (VLS) and intramuscular electromyography (EMG). In contrast to the control group, no vocal cord muscle atrophy was found on the light microscopy in experimental group rabbits.

DISCUSSION AND CONCLUSION

Inter-recurrent free nerve graft transposition can be considered in patients with iatrogenic recurrent nerve transection
