title: [Laser: otology, oto-neurosurgery].
abstract: The use of lasers in otology is rather recent and their use in otoneurosurgery is even more so, as shown by the limited number of publications dealing with this subject in the literature. After a review of the main bibliographical data on these subjects, the authors present their experience and analyze their results. Two types of lasers were used successively, an Argon laser and then a laser with a double KTP 532 and Nd: YAG 1320 nm beam. The Argon laser and the KTP 532 laser were exclusively used in otology whereas in otoneurosurgery, both KTP 532 and Nd: YAG 1320 nm beams were used depending on the indications. The KTP 532 beam appears to be preferable for treating vascular and small-sized lesions; the Nd: YAG 1320 nm beam proves to be very advantageous for vaporizing the slightly vascular, larger lesions such as stage III and IV neurinomas of the VIIth.
