[Injuries of the ossicle system].

On the basis of the observation of eight cases with traumatisms of the ossicular system, the authors discuss the mechanism of various forms of lesions, which may be primary represented by fractures and luxations or they may be secondary reactions following the traumatism leading to ankylosis the joins. There is underlined the frequency of the luxations of the stapes and the constant ankylosis of the footplate in these cases. The authors argue in favour of an early surgical procedure, the extent of the surgical intervention being conditioned by the lesional aspect.
