  • Medial
  • At the hinder part of the medial wall of the vestibule is the orifice of the vestibular aqueduct, which extends to the posterior surface of the petrous portion of the temporal bone. (wikipedia.org)
  • Winding around the inferior peduncle and crossing the area acustica and the medial eminence are a number of white strands, the striƦ medullares, which form a portion of the cochlear division of the acoustic nerve and disappear into the median sulcus. (wikipedia.org)
  • modiolus
  • In such cases, it is possible that a patent or semipatent cochlear aqueduct or modiolus would allow for hydrodynamic changes in pressure to occur concurrently with volume changes between the perilymph and spinal fluid in the adjacent subarachnoid space, but this is difficult to confirm.

  • 001). Structures near the spatial-resolution limit of MSCT (e.g., bony covering of the tympanic segment of the facial canal, the incudo-stapedial joint, the proximal vestibular aqueduct, the interscalar septum, and the modiolus) had higher contrast and less partial-volume effect with VCT.

  • Full
  • In order to diagnose the cause of the enlarged vestibular aqueduct the physician will need a detailed family history, full examination to include vestibular examination and, if a bilateral finding, molecular genetic testing as appropriate. (wikipedia.org)
  • Open
  • Either or both of the displacement of the eardrum when the stapedius muscle is stimulated or the aural acoustic compliance of the eardrum is measured and provided the cochlear aqueduct is open. (google.com)
  • round
  • What percent of patients will have new bone growth covering the round window niche and membrane during cochlear implantation? (brainscape.com)
  • Base
  • at the apex of this is a small opening, the aquaeductus cochleae (or cochlear aqueduct, or aqueduct of cochlea), which lodges a tubular prolongation of the dura mater establishing a communication between the perilymphatic space and the subarachnoid space, and transmits a vein from the cochlea to join the internal jugular Base of skull.
