Abstract:
The Acute effects of Nd-YAG 1.06 laser on the normal brain were studied in experimental animals, with the different powers of 60W, 70W and 80W applied for 7 seconds. The lesion was examined after Nd-YAG 1.06 laser exposure 30 minutes. The diameter of the lesion was consistenty greater than the depth. Beside of the vaporized zone, there is the region, which diffuse regularly in the surrounding normal cerebral tissue. These findings indicated that by using short, intermitent pulses of the power of 60W, 70W and 80W, damage surrounding tissue can be controlled and the Nd-YAG 1.06 laser can be used safely as an adjunctive measure for vaporization with the effects of homeostasis in many neurosurgical procedures. It is necessary to study the chronic lesion of Nd-YAG 1.06 laser on normal brain before the application of this device in neurosurgery.
