[Gherini-Causse endo otoprobe and HGM argon laser. Value in the surgery of ear abnormalities].

Performing a stapedectomy in a slightly fixed otosclerotic footplate may induce an excessive motion of the labyrinthine fluids, damaging inner ear membranes and Corti hair cells fragilized by proteolytic enzymes. The fluid motion in the cochlear canal is quantic size only. The replacement of a slightly fixed footplate by an ideal compliance and impedance transmitting device, may allow the surgeon to get a tremendous improvement of hearing (as a Meniere disease). The Gherini-Causse multi-use endo-otoprobe combined with a HGM Argon Laser, if associated with a Skeeter Oto-tool drill, looks to be an efficient and safe solution to this otologic surgical challenge.
