  • Abstract
  • Look Inside

 Eleven temporal bones (10 cases) with histological endolymphatic hydrops were studied. Primary sites studied were the vestibular aqueduct and endolymphatic sac including measurement of the proxysmal rugose portion, and graphic reconstruction of the vestibular aqueduct. Four ears showed hypoplastic vestibular aqueduct and endolymphatic sac. Three ears showed endolymphatic sac pathology such as flattened epithelial cells, increased connective tissue and small lumen. A ear showed bony obliteration of the vestibular aqueduct at the isthmus portion presumably due to bacterial labyrinthitis. Significance of these pathological findings as the etiology of the endolymphatic hydrops were discussed.
