Abstract
The hypocycloidal polytomograpic temporal bone studies performed on 2683 patients were reviewed and the radiographic appearance of the vestibular aqueduct was evaluated. Within this group of 5366 ears, 47 ears (1%) in 26 patients demonstrated a large vestibular aqueduct (diameter > 1.5 mm). A review of the prevalent embryology, anatomy and physiology is reported. A discussion of hypocycloidal polytomography and computed tomography of the temporal bone as well as a discussion of the Mondini dysplasia is also presented. The 26 patients underwent a battery of audiometric and vestibular function tests. These data were compiled and correlations made, allowing for a more complete characterization of the large vestibular aqueduct syndrome.
