Correct Answer: Meniere's disease
Description: Intermittent low-pressure pulse therapy It is observed that intermittent positive pressure delivered to inner ear fluids brings relieffrom the symptoms of Meniere's disease. Not only there is improvement in veigo, tinnitus and ear fullness, but hearing may also improve. Intermittent positive pressure waves can be delivered through an instrument called Meniett device which has been approved by FDA. A prerequisite for such a therapy is to perform a myringotomy and inse a ventilation tube so that the device when coupled to the external ear canal can deliver pressure waves to the round window membrane the ventilation tube. Pressure waves pass through the perilymph and cause reduction in endolymph pressure by redistributing it through various communication channels such as the endolymphatic sac or the blood vessels. Some believe they regulate secretion of endolymph by the stria vascularis. Patient can self-administer the treatment at home. It may require a few months before complete remission of disease is obtained. Meniett device therapy has been recommended for patients who have failed medical treatment and the surgical options are being considered. Ref : Diseases of ENT by Dhingra 6th edition Pgno : 104,105
