Voice disorders in the elderly.

Abstract

A review of the literature clearly shows that connective tissue degeneration in the larynx, particularly of elastic and collagen fibers, is more prevalent in males than in females. Reinke's edema or polypoidal degeneration of vocal cords may or may not be more common in females. Whether or not the above statements are true, tissue atrophy causes a problem in males because the voice becomes higher pitched, weak or reedy, less masculine, whereas polypoidal change in the older female larynx results in a lower pitch, husky voice that would be acceptable in a male but makes the female voice more male-like and undesirable. Functional misuses of laryngeal muscles come into play when patients try to compensate for these changes. The etiology of dysphonia in the elderly gets even more confusing when psychological factors such as loneliness and depression add their effects to laryngeal muscle misuse. Laryngeal cancer is still probably the most common cause of hoarseness in older persons. Unfortunately the biopsy to rule out cancer in a person who is hoarse from degenerative or functional causes will often greatly worsen the dysphonia and render voice therapy less effective.
