“…These positive findings together with extensive literature on improvement in limb musculature following physical exercise programs in the elderly and the documented relationship between physical condition and voice [49,98] support application of these treatment principles to improving the aging voice. It has been suggested that approximately 12% of aged individuals receive voice treatment [108,109].…”

This paper will provide a review of aspects of vocal aging within the context of general body aging and describe two data sets related to the aging voice. Data will be presented which document pre- to posttreatment improvement in select voice characteristics (sound pressure level, subglottal air pressure, thyroarytenoid laryngeal muscle activity and voice quality) following application of an intensive voice treatment program (the LSVT^®) to 3 individuals with aged voice. Additionally, physiological data (forced expiratory volume, visual accommodation, bone density, taste discrimination, white blood count and resting heart rate) and select perceptual (perceived age) and acoustic measures (reflecting both cycle-to-cycle and longer-term intensity and frequency stability) from 67 subjects will be reviewed from the work of Gray and colleagues to document the differential impact of the global aging process across organ systems including the aging voice.

“…Glycoproteins such as mucin contribute to the viscoelasticity of the mucus in the airways [19], and the physical properties of the fluid are known to vary as a result of autonomic nerve stimulation [1,[20][21][22][23], administration of drugs [24], and albumin leakage. In addition, the number of laryngeal glands and their distribution changes with age [25,26], and the viscosity of the laryngeal mucus presumably increases in the aged. In this study, physiological saline was used in the low-viscosity respiratory fluid model, and a solution of CSSS dissolved in saline was used in the high-viscosity fluid model.…”

To evaluate how the viscosity of the laryngeal mucus influences vocal fold vibration, two fluids of differing viscosity were applied separately to excised canine larynges and experimental phonation was induced. Vibration of the vocal folds was measured by use of a laryngostroboscope and an X-ray stroboscope. With the high viscosity fluid, the amplitude of vibration of the free edge and the peak glottal area was decreased while the open quotient was increased. Because the viscosity of this fluid affected the wave motion of the vocal fold mucosa, changes in viscosity of the mucus may be involved in causing such disorders as hoarseness, in the absence of apparent changes in the vocal folds themselves.

“…Hirano et al [5] described the thinness of vocal folds of the larynx in male patients after the age of 70. According to Gray and Morrison [6,7] vocal folds edema is more common in elderly female patients, whereas in men the atrophic form appears more frequently. Edematous changes refer mostly to the superficial layer of the lamina propria.…”

Vocal folds play a crucial role in voice production. The physiological vibrations of vocal folds depend on the unchanged multilayered structure of the vocal folds mucosa. Morphological changes of mucosa are the cause of voice quality disorders -dysphonia. The aim of this study was to determine the morphological base of dysphonia in patients with vocal folds atrophy. A group of 24 patients with larynx atrophy confirmed by endoscopic (VLS) and stroboscopic (VLSS) examination of the larynx was included in the study. The morphological assessment of the larynx mucosa was carried out with the use of the transmission electron microscopy (TEM). Ultramorphological examinations revealed changes in the epithelium, basal membrane and lamina propria of the vocal folds mucosa. An increased number of collagenous fibers, fibroblasts with signs of vacuolar degeneration inflammatory cells and a decreased number of blood vessels and pericytes were observed. Morphological changes found in the epithelium, basal membrane and lamina propria of the vocal folds mucosa were the cause of disorders of vocal folds vibrations registered in the stroboscopic examination of the larynx (VLSS).
