title: [Value and limitations of the use of CO2 laser in neurosurgery. Reflexions from a French experience].
abstract: The authors have been using routinely since February 1983 a french 80W. CO2 Laser unit. They discuss the advantages and limits of this technic in the light of the first 26 intracranial and intraspinal operations carried on with it. The main and wellknown qualities of CO2 Laser are: the easiness of the hemostasis of the tumor and of the surgical cavity; and the absence of traction on the same tissue. The coupling of CO2 Laser with the operating microscope appeared very useful and made safer deep tumor excision, particularly that of the posterior fossa such as neurinomas and meningiomas. It was also quite efficient for intra-orbital tumors. The maniability of the hand piece was increased by the use of oblique mirror (45 degrees and 60 degrees) fixed at its extremity. The incision of skin, subcutaneous and muscular layers was not simplified by CO2 Laser; indeed this apparatus increased the operatory duration and was responsible of a healing time extension.
