[Significance of lasers in surgery of cerebellopontine angle tumors].
The use of the laser in otology has demonstrated its effectiveness and safety. The aim of this paper is to show its application in otoneurosurgery. After comparing the advantages and disadvantages of various lasers (Yag, CO2, KTP), we soon opted for the KTP laser, which we have since used exclusively in otology and otoneurosurgery. 25 patients with cerebello-pontine angletumours were operated using the KTP laser (22 neuromas and 3 meningiomas). Although in the absence of rigourous methodology it is difficult to assert the superiority of the laser over the classical techniques of resection, the results seem better since we have been using the laser for otoneurosurgery, especially for facial function. In any case, the laser is merely an instrument, which it is necessary to learn to manipulate; it does allow lesions to be vaporized without traction, and has a haemostatic action. It should never be used directly in contact with nervous structures, especially nerves. It seems to us to be most helpful in dealing with large and very vascular tumours.
