The microsphere surface technique for evaluation of cochlear vessels and circulation. A preliminary report.

A new technique for the evaluation of cochlear microcirculation and cochlear vessels is described. This method is a modification of two previously used techniques, the "soft-surface-specimen method" and the "microsphere method". In this preliminary paper it was found that the microspheres were easily visualised in all cochlear tissues. The absolute and relative distribution of microspheres was calculated. The method appears promising for experimental investigations of cochlear microcirculation.
