[Means of fixing a transmission device to the center of a mobile footplate].
The authors present a new fixation device for any bony or prosthetic transmission system to the center of a mobile footplate in the absence of the stapes crura. It is a disc-shaped silicone sponge, with a central hole, fitting the bottom of the oval fossa and thus securing the maintenance of the bony or prosthetic transmission in the center of the mobile footplate, and reducing the risk of shifting of the transmission system, which is always possible in case of tympanic retraction. The silicone sponge allows as well a more physiological transmission, because the footplate will vibrate from top to bottom thanks to a central force vector, thus giving better audiometric results. The biocompatibility of the silicone sponge eradicates any phenomenon of intolerance from the tissues.
