title: Endolymphatic sac valve implant surgery. II: The unidirectional inner ear valve implant.
abstract: A unidirectional inner ear valve implant was developed to direct excess endolymph out of the inner ear in the hydropic state (Ménière's disease) into the mastoid cavity. A detailed technical description of the valve implant is presented as well as some technical aspects of the valve implant based on the surgical anatomy of the endolymphatic sac.
