The measurement of width and thickness in human stria vascularis

Abstract

Under light microscope, the width and the thickness of human stria vascularis were measured. Among 214 cases 386 temporal bones, 20 ears were selected, because they had little artifacts and no abnormal findings in Corti organ and endolyphatic space. Twenty adults temporal bones ranging in age 48 to 75 and 2 new-borned temporal bones were examined at basal turn and middle turn.
Results were as follows:
1. The width of stria vascularis at basal turn was 337.1±36.8μ and at middle turn 272.2±39.0μ.
2. The thickness of stria vascularis at vasal burn was 27.7±6.0μ and at middle turn 29.0±6.3μ.
3. There was little difference between adults and new-borned baby in width and thickness of stria vascularis.
