Abstract

Qualitative and quantitative changes to the extracellular matrices occur in the vocal fold mucosa of the aged. Specifically, changes take place in the three-dimensional structure of the extracellular matrices, in the morphological structure of each extracellular matrix, and in the viscoelastic properties of the vocal fold mucosa. Histological changes in the aged larynx influence the viscoelasticity of the vocal fold mucosa as a vibrating tissue and vocal fold vibration, and are related to the geriatric changes in the voice. When we correlate the geriatric morphological changes of the vocal fold as a vibrating tissue with voice function of the aged, the pathophysiology of the voice function of the aged can be well explained. Significant differences in the histological changes of the aged larynx are found from one individual to another, just as there are individually recognizable differences in geriatric changes in the voice.
