Abstract

With recent developments in laser technology, high power diode laser and optical delivery systems have become highly promising surgical devices with advantages of lower cost and higher precision. The aim of the present study was to test the 980 nm wavelength laser (Opto Power OPC-D010-980-FCPS) for its potential use in neurosurgery. Response of neural tissue to different energy levels of laser irradiation was investigated with different exposure durations in a dosimetric study using Wistar rats. Laser-induced lesions were placed stereotactically in anesthetized Wistar rats both cortically and subcortically. In order to investigate the lesioning effects of the 980 nm diode laser as a function of pulse duration, laser power was varied between 0.5 to 3.0 Watts with 0.5 to 3.0 sec exposures. Histologic investigation of brain specimens indicated that the 980 nm wavelength high power diode laser has the potential to be used for coagulation/ablation with proper selection of energy level and exposure duration.
