Pre-dissection (R1, V1) and post-dissection (R2, V2) EMG waveforms of the rightand left sides' vagal nerve (VN) and RLN were evaluated.Results: There were 29 females and 5 males patients with mean age of 43.85±13.86 years. 61 nerves at risk were successfullyevaluated with I-IONM. Mean R1 and R2 amplitudes of the right RLN were 280±10 ?V and 270±9?V; the left RLN were 270±10?V and260±9?V respectively. Mean V1 and V2 amplitudes of the right VN were 210±7?V and 190±7?V; the left VN were 190±5.4?V and170±5?V respectively. Mean R1 and R2 latencies of the right RLN were 2.03±0.42mS and 2.0±0.46mS; the left RLN were 1.90 ±0.30mS and 1.96 ± 0.33mS respectively. Mean V1 and V2 latencies of the right VN were 1.91±0.46mS and 1.82±0.52mS; the left VNwere 2.01±0.34mS and 2.07±0.38mS respectively. There was no statistically significant difference between the sides in terms of EMGwaveforms of the VN and RLNen10.37696/nkmj.719020info:eu-repo/semantics/openAccessArticle82131137460100
