Functional and Physical Outcomes following Use of a Flexible CO2 Laser Fiber and Bipolar Electrocautery in Close Proximity to the Rat Sciatic Nerve with Correlation to an In Vitro Thermal Profile Model

Figure 5

Hematoxylin stained nerves (vertical arrows) exposed to different laser powers: 2, 5, and 10 Watts (W). The left column shows sections at low magnification; the right column shows the same samples at a higher magnification. At 2 W laser power setting, the neural sheath of the nerve was ablated without obvious additional damage to the nerve bundle ((a) and (b)). At 5 W and 10 W laser power settings, severe ablation of the nerve is evident ((c), (d), (e), and (f)). Also note the margin of deeper thermal damage evidenced by staining differences (double headed arrows).
