Case statistics of RLN injury.

Case	Lobe	Signal attenuation	Injury point	Injury cause	Recovery (months)
1	Left	70%	The point of entry into the larynx	Excessive stretching of RLN when picking up thyroid lobes	0.5
2	Left	100%	1 cm from the point of entry into the larynx	Tumor was adhered to RLN.	No recovery in 12 months.
3	Left	90%	The point of entry into the larynx	Heat injury caused by ultrasound knife during separating.	6
4	Right	90%	1 cm from the point of entry into the larynx	Clamping of vessel to stop hemorrhage included and injured the RLN	3
