The Block Surface Method for Evaluation of Human Inner Ears

Abstract

Experience with the application of the block surface technique to human inner ears, its advantages and problems are discussed. The usefulness of this technique depends essentially on the fixation quality, which is directly related to the postmortem time delay of efficient fixation by perilymphatic perfusion. Some typical structural features of the human inner ear are shown.
