Horizontal ocular deviations was induced by pressing against the middle ear ossicles in two cases of Ménière's disease and were identified electronystagmographically during Rosen's chorda tympani sectioning operation, under local anesthesia.In other one case of Ménière's disease, the patient complained that the surroundings were moving towards the side of the diseased ear when the external meatus of the diseased ear was pressed.It was assumed that a slight inward deflection of the foot plate of the stapes in the diseased ear induced the conjugate horizontal ocular deviation towards the opposite side and the sensation of shifting of the objects to the same side.A pseudo-fistula symptom in Ménière's disease might be related to the saccular hydrops which was frequently reported as being found among tissues obtained at the time of autopsy in cases of Ménière's disease.
