  • Title: The effect of cerebrospinal fluid pressure on perilymphatic flow in the opened cochlea.
    Author: Salt AN, Stopp PE.
    Journal: Acta Otolaryngol; 1979; 88(3-4):198-202. PubMed ID: 495071.
    Abstract:
    Scala tympani of guinea pigs was perfused with elevated potassium solutions whose concentraus recovery, the concentration curve showed a 'break' approximately 3 min after perfusion ceased. When the CSF pressure was released by opening the cisterna magna, cochlear flow was markedly reduced, and the recovery curve became smoothly exponential, following a much slower return to control levels. This finding lends support to the idea proposed by Moscovitch, Gannon & Laszlo (1973) that longitudinal flow of CSF contributes to perilymph efflux in the patent cochlea.
