    Notes: Summary The authors have been using CO2-laser radiation routinely for more than 2 years. After having recalled the basic thermal properties of this beam, they present their experience. The goal of this work is to point out the particular benefit of CO2-laser cautery to perform tumoral haemostasis. The technical data of this CO2-laser haemostasis are detailed for 3 main indications: 1. In cases of a precise origin of the haemorrhage, the coagulation of small intratumoural vessel necessitates a low output power: 2–4 watts in continued emission; 10–15 watts in the pulsed mode. The beam must be defocussed so as to be as large as the aimed vessel. A micro-manipulatotor is necessary for deeply located tumours. Basal meningiomas, neurinomas, giant adenomas are the best indications. 2. If a diffuse bleeding is encountered in the operative cavity the output must be a little higher: 3–8 watts in continuous mode or 15–30 watts in the pulsed mode; first the cavity is swept with a defocussed CO2-laser ray; then the few larger vessels which have not been cauterized are coagulated one by one either by laser or by bipolar coagulation. 3. The insertion zone of a meningioma can be efficiently coagulated by CO2-laser: a 150–200 watts output in the pulsed mode is necessary if the attachment is dural, a 300–400 watts pulsed output in the case of bony infiltration.

    1.32 μm Nd:YAG laser during neurosurgical procedures experience with about 70 patients operated on with the MC 2100 unit (1990)

    Notes: Summary The authors present their clinical experience with 1.32 μm NdYAG Laser. After a series of experimental studies which demonstrated the adaptability of such a wavelength to central nervous surgery, they used such a Laser during current neurosurgical procedures. The MC 2100 unit combines two wavelengths 1.32 μm and 1.06 μm, and two emission modes: continuous wave (c.w.) and pulsed. This Laser has been used during 70 procedures: 54 supra-tentorial, 8 infra-tentorial, 5 intra-spinal, 3 intra-orbital. 600 μm and 400 μm fibers were preferred in most cases, either with a telescopic light handpiece or-less often—with a focussing handpiece. The quality of vaporization—close to that of CO2 Laser—and of haemostasis —close to that of 1.06 μm Nd-YAG Laser—makes this 1.32 μm wavelength very suitable for neurosurgery. The manoeuverability due to the optic fibers is most interesting. Furthermore, such a Laser should have in the near future large applications in stereotactic and/ or endoscopic neurosurgery.
