[Presentation and treatment of stapes dislocation and subluxation (author's transl)].
The symptomatology, especially vestibular, and the surgical findings in traumatic dislocation of the stapes into the oval window are described in 2 patients, one of whom seen 1 3/4 h after the accident and the other after 12 days. The main indication for exploratory tympanotomy was change of the spontaneous nystagmus from an irritative to a paretic type. Special attention should be given to positional nystagmus, which increases on turning onto the affected side, the mechanism for which is apparently similar to the positional vertigo of labyrinthine fistulae. Hearing was preserved in both patients. In one patient, vestibular function recovered considerably whilst in the other, there remained considerable impaired function.
