The Comparative Morphological Evaluation of Human Male and Female Vocal Folds, A Cadaveric Study.

摘要

ABSTRACT The age related structural changes in human vocal fold are known, but gender related differences in middle aged group are not precisely documented. This study is aimed to compare and evaluate the collagen, elastic fibre content of the lamina propria of middle aged male and female vocal folds. Cross sectional analysis of human cadaveric male and female vocal folds were performed. Haematoxylin & Eosin staining was used for the morphometric analysis and Verhoeff's & van Giesen stain for t.
