Four cases suffering from intractable vertiginous attacks with Meniere's disease were treated by a middle ear pressure device, i. e. Meniett®, fo2ry ears. In allc ases, v ertigow as controlledb v 4 months aftert he start of the pressure treatment. Three cases had reappearance of the vertigo when the tympanostomy tube was troubled in one case, when the device was used less frequently than recommended in one case and when the pressure pulse was weakened because of the device trouble in one case. These finings suggested that the middle earpressure treatment should be continued for at least 3months, and otolaryngologists shouldpay attention to both tympanostomy tube and device trouble at the time of reappearance of vertigo.
