| Popis: | Objectives/Hypothesis To measure the volume of the endolymph drainage system in temporal bone specimens with Meniere disease, as compared with specimens with endolymphatic hydrops without vestibular symptoms and with nondiseased specimens Study Design Comparative human temporal bone analysis. Methods We generated three-dimensional models of the vestibular aqueduct, endolymphatic sinus and duct, and intratemporal portion of the endolymphatic sac and calculated the volume of those structures. We also measured the internal and external aperture of the vestibular aqueduct, as well as the opening (if present) of the utriculoendolymphatic (Bast's) valve and compared the measurements in our three study groups. Results The volume of the vestibular aqueduct and of the endolymphatic sinus, duct, and intratemporal endolymphatic sac was significantly lower in the Meniere disease group than in the endolymphatic hydrops group (P |
