     It is not easy to treat patients with intractable Meniere's disease. Intratympanic injection of gentamicin or steroid is one option. The other is a surgical procedure like endolymphatic shunt surgery. Middle ear pressure treatment using the Meniett device, which has not been approved by the Japanese government is widely accepted in foreign countries. We had a chance to use this Meniett device under approval of the ethic's committee of Hino Municipal Hospital since September 2004.〈Methods〉Four patients with intractable Meniere's disease who suffered intensive vertigo attack for more than 5 months with conservative medical treatment were employed in the study. Ages ranged from 67 to 72, with 3 females and 1 male. After a ventilation tube was inserted under local anesthesia, treatment with the Meniett was performed 3 times a day at home.〈Results〉Two patients improved and 2 slightly improved concerning vertigo attacks. One showed no change, 1 experienced a worsening, and 2 showed slight improvement concerning the hearing level.〈Conclusion〉The Meniett device is less invasive and may be suitable for elderly patients who prefer conservative treatment. The mechanism involved in the reduction of vertigo attacks is not clear so far, but we speculate that middle ear pressure may suppress serum vasopressin (antidiuretic hormone) secretion and thereby reduce endolymphatic hydrops. It is necessary to accumulate treatment data with the Meniett in Japan to obtain official approval by the government.
