Background
• Structural changes of the larynx caused by aging
• US 2010 Census, age 65 and over population
was 40.3M (13%)
• Incidence of vocal disorders in aging population:
12-35%
• Lifetime prevalence of 47% for age >651
– 25% of pts >65y.o. w/ vocal complaint had
presbyphonia2

Background
• Quality of life affected
– 13% noted QOL to be moderately to
profoundly reduced related to dysphonia.3
• Avoiding social events
• Frustration and need to repeat oneself
• Change in identity
3. Golub et al.(2006)

Background
• Can guess age on basis of speech alone4,5
• Character
– Weak
– Thin
– Breathy
– Reduced projection
– Decreased range
– Unsteadiness
– Pitch change4. Ryan et al.(1974)
5. Linville et al. (1985)

Background
• Speaking
Fundamental
Frequency decreases
with maturity then
rises
• VF vibrate more
rapidly as age
advances

Molecular Etiology
• Loss of vocal fold viscoelasticity
– Collagen disorganisation
– Less Hyaluronic acid and elastic fibers decrease
– Decreased pliability and vibration
• Muscle atrophy
– NMJ similar to denervated muscles
– Reduction in axon terminal area and unoccupied postsynpatic Ach receptors
• Calcification of laryngeal cartilage
– Limit ROM, altered resonance 7. Johns III, et al. (2011)

Gross Etiology:
laryngoscopy/stroboscopy
• Vocal fold atrophy and bowing
• Midline glottic gap and air escape
• Aperiodic / irregular vibration, increased
amplitude, asymmetric wave
• Prominence of vocal processes
• Edema
![Page 11: Voice Restoration in Presbyphonia - GBMC](https://reader035.vdocuments.site/reader035/viewer/2022062312/62a7da04078c4b5ba20257e2/html5/thumbnails/11.jpg)

Etiology
• Also multifactorial, outside larynx
– Lungs
– Kyphosis
– CNS
– Dental/mandibular
– Dry mouth

Management Options
14
• Reassurance
• Voice therapy
• Medical optimization
• Surgical management
![Page 15: Voice Restoration in Presbyphonia - GBMC](https://reader035.vdocuments.site/reader035/viewer/2022062312/62a7da04078c4b5ba20257e2/html5/thumbnails/15.jpg)
Management options: voice
therapy
• 1st line treatment
• Strengthening exercises for respiratory and phonatory control (Lee
Silverman Voice Therapy)
– Practice producing resonant tone
– Emphasis on sustained high pitch and loud voice production
– Vocal postures
– Vocal function exercises
• Shown to lead to subjective improvement in QOL and perceived
voice8
• Less beneficial in severe cases (higher VF atrophy, larger glottic
gaps, glottic closure pattern, burden of medical problems)9

Management options: injection
laryngoplasty
16
• Goal to improve glottic closure
• Temporary effect
• Serve as a trial for a more permanent
procedure
• May avoid general anesthesia
• Risk of Superficial injection, over-injection
![Page 17: Voice Restoration in Presbyphonia - GBMC](https://reader035.vdocuments.site/reader035/viewer/2022062312/62a7da04078c4b5ba20257e2/html5/thumbnails/17.jpg)
Injection laryngoplasty
• Can be performed in-office as an awake
procedure
– Allow vocal titration, technically challenging
– Anticoagulation is relative contraindication to
office-based procedures
• Or in the OR, under general anaesthesia
– More control
– Does not allow for titration

Injection laryngoplasty
• Materials/Fillers– Permanent/Long lasting
• Autologous fat – 1 to several years
• RadiesseTM (calcium hydroxyapatite) – 12 months
• Polydimethylsiloxane (PDMS or particulate silicone) – likely permanent, >10yrs
– Temporary• GelfoamTM (bovine gelatin) – 4-6 weeks
• Collagen based products (CymetraTM, ZyplastTM, CosmoplastTM) – 2-4 months
• Hyaluronic acid (RestylaneTM, HyalaformTM) – 4-6, up to 12 months
• Carboxymethylcellullose (Radiesse voice gelTM) – 1-3 months

Bilateral Medialization thyroplasty
• Provides static medialization of
the vocal folds
• Permanent but reversible
• OR – local anesthetic & conscious
sedation
• Implant placed in paraglottic
space while patient phonates

Medialization thyroplasty: risks
• Risk of implant extrusion, FB reaction
• Risk of airway obstruction
• Risk of hematoma
