1. The purpose of this study is to develop a validated computational model for assessing
normative change in these patterns in patients with vocal cord atrophy before and after
voice therapy.
2. This is a prospective study comparing two cohorts - patients with vocal cord
atrophy(VCA) (G1) and healthy controls (G2). Subjects with VCA will receive a cone beam
computed tomography (CBCT) scan with the standard laryngeal protocol before and after
voice therapy. Healthy controls will also receive one cone beam computed tomography
(CBCT) scan. Subjects with VCA (G1) will undergo post-therapy scans approximately 4
weeks after completion of voice therapy treatment. Enrolled subjects will also undergo a
video stroboscopy and acoustic/aerodynamic testing. Subjects in G1 typically have these
procedures performed before and after voice therapy as standard of care. Participants in
G2 (healthy controls) will have the video stroboscopy and acoustic/aerodynamic testing
just once since they would not otherwise be scheduled to undergo voice therapy.
Potential subjects will be between 65 and 80 years of age will be considered for the
study if they qualify based on inclusion criteria. Potential subjects will undergo are
pre-screening process involving an initial telephone screening.
3. Raw data (measured and calculated) derived from this pilot study will be reported, and
no statistical analysis will be performed. Data from specific aim 1 (G2) and specific
aim 2 (G1) will be compared using graphical representations such as bar and dot plots.
There is a potential for the loss of confidentiality; however, every reasonable effort
will be made to limit breaches of privacy and confidentiality. Subjects may directly
benefit from this study. In addition, data and conclusions derived from this study may
help future patients regarding the effects of vocal therapy on vocal cord atrophy (VCA).
The investigators will recruit up to 12 subjects to account for screen failures. Once 8
eligible subjects are enrolled (4 per group), then enrollment will end.

Healthy Subjects Cohort:
Inclusion criteria:

- Voice Handicap Index (VHI) questionnaire score of less than 10.
- Little or no dysphonia as assessed by a speech language pathologist from the Duke
Voice Care Center
- No contraindications to have a CBCT scan (as assessed per standard clinical practice)
Exclusion criteria:
- Inability to speak, read, write, and understand English
- Inability to provide written consent
- Self-reported or known allergy to Afrin or Tetracaine HCL (or related class of drugs)
and unable or willing to complete the laryngovideostroboscopy procedure with it.
Vocal Cord Atrophy Cohort:
Inclusion criteria:
- Between 65 and 80 years of age
- Clinical diagnosis of vocal cord atrophy (VCA)
- Treated for the above condition by a provider at the Duke Head and Neck Surgery &
Communication Sciences Clinic
- Elected to undergo voice therapy as standard of care for treatment of VCA
Exclusion criteria:
- Other conditions that affect the voice and would interfere with study measures, as
determined by PI
- Inability to speak, read, write, and understand English
- Inability to provide written consent
- Self-reported or known allergy to Afrin or Tetracaine HCL (or related class of drugs)
and unable or willing to complete the laryngovideostroboscopy procedure with it.
