Presbyphonia

Module Summary

Presbyphonia is a change in the voice resulting from physiological changes related to aging. These changes involve the entire person but particularly include changes related to the laryngeal structures. In the majority of elderly people with vocal symptoms the cause is multifactorial and specific laryngeal lesions should be pursued. Metabolic, autoimmune and neurologic diseases are more common in the elderly and should be ruled out as well. Patients present with several characteristic symptoms that include vocal weakness, reduced projection, changes in pitch and vocal fatigue. Characteristic findings on laryngoscopy include a persistent glottic gap usually associated with vocal fold bowing and prominence of the vocal processes. Treatment typically begins with speech therapy but may involve vocal fold injection and/or thyroplasty.

Module Learning Objectives

Incidence

    1. 20% of patients older than 65 years reported dysphonia of any kind.
  2. Quality of life issues
    1. Weakening of voice resulting in increased effort, increased fatigue and avoidance of social situations

Patient Evaluation

Learning Objectives 
  1. Know common presenting symptoms:Weak or breathy voice, changes in pitch, decreased projection, reduced vocal stability.
  2. Findings on laryngoscopy
    1. Vocal fold bowing, vocal fold atrophy, prominence of the vocal processes, vocal fold edema (more common in women)
  3. Diagnosis of exclusion.

Surgical Therapies

Learning Objectives 
  1. Understand role of vocal fold medialization

Case Studies

  1. A 74 year old female presents with five-year history of breathy quality to her voice. She is a university professor, retired, but continues to lecture. Her voice begins to tire after 15 minutes and is unable to lecture more than one hour. She is only aware of this when she is lecturing, but others, especially husband who wears a hearing aid, are aware of weak voice quality and difficulty hearing her in areas with background noise. What additional history would you require? What would you expect to see on exam? What additional testing, if any, in needed? What would your initial treatment recommendations be?
  2. An 85-year-old man describes a gradual loss of voice but no difficulties with swallowing or airway. His history is negative for cerebrovascular accident or other neurologic disease. He is independent in activities of daily living. Examination showed vocal fold bowing. A trial of speech therapy by a qualified voice therapist has been completed with some improvement but he is interested to see what additional treatment can be offered. What, if anything, can you offer as further treatment?

Complications

Learning Objectives 

Know the differential diagnosis for conditions that can be mistaken for Presbyphonia.
