To enhance the treatment effects for intractable Meniere's disease, we tried to expose the opened endolymphatic sac to high concentrations of steroids. This technique - endolymphatic sac drainage and steroid-instillation surgery (EDSS)-involves the application of a mass of prednisolone followed by absorbable gelatin sponges soaked in a high concentration of dexamethasone into the sac lumen opened and expanded with a bundle of absorbable gelatin films. The long-term results of vertigo control and hearing improvement treated with the above techniques were excellent. However, some cases suffered from revisited vertigo even years after EDSS, because endolymphatic sac surgery including EDSS was not ablative but conservative surgery. We experienced a revision surgery of EDSS and obtained a good result. Here, we descride surgical observation of the first and second operations and discuss the significance of revision surgery.
