  • Abstract
  • Look Inside

 The excessive flow of perilymph during stapedectomy or fenestration procedure was not seen in all of the 17 cases. In the case of Meniere's disease operated by endolymphatic subarachnoid shunt operation, however, cerebrospinal fluid gushed out from a small opening made in the meningeal dura through the medial wall of the sac filling the mastoid cavity.

 On the basis of these clinical observations the pattency and the function of the cochlear aqueduct were discussed. The authors conclude that the cochlear aqueduct is not an open channel between the perilymphatic space and the spinal fluid system. However, the physiological significance of the aqueduct is yet to be found.
