P-100 in the treatment of Ménière's disease: a clinical study.

Patients suffering from Ménière's disease are particularly sensitive to negative pressure in the middle ear. For example, attacks of vertigo can be triggered by a descent in an aircraft when ventilation of the middle ear can become critical. Positive-pressure pulse treatment has been shown to have a beneficial effect on the symptomatology and is now a true alternative in the treatment of Ménière's disease. In this study, we compared two devices that produced positive-pressure pulses delivered to the inner ear via the external ear canal and after the insertion of a middle-ear ventilation tube. Both devices (Meniett and P-100) were equally successful and confirmed that positive-pressure pulse treatment is a true alternative to current treatment modalities. However, the P-100 is the preferred device, particularly for its convenience of use and its cost, which is considerably lower.
