Figures & data
Figure 1 Hematoxylin and eosin staining showed all damage of the nerve, even damage close to (1 mm away from) the recurrent laryngeal nerve (arrows).
Note: Scale bar =50 μm.
Figure 2 Some coagulation damage (blue arrow) of the surrounding fat and collagenous tissue, which in one instance was within a distance of ~100 μm of the nerve fascicle, without causing damage to the nerve fascicle (red arrows).
Notes: Hematoxylin and eosin staining was used. Scale bar =50 μm.
