Cough, Dysphagia, Dysphonia, Vocal Cord Atrophy, Vocal Cord Paralysis, Vocal Cord Paresis
Conditions
Brief summary
Investigators will assess the usefulness of using ultrasound in office procedures for laryngology interventions. Participants who qualify will be adults who are undergoing superior laryngeal nerve block, injection laryngoplasty, swallowing evaluation, voice evaluation and voice therapy.
Interventions
DIAGNOSTIC_TESTUltrasound for dysphagia
Patients with and without swallowing complaints will be enrolled to assess their tongue, suprahyoid and infrahyoid musculature, including muscle identification, bulk and function.
DIAGNOSTIC_TESTUltrasound for dysphonia
Adult patients who are seen at the Sean Parker Institute for the Voice and are determined to have muscle tension dysphonia will undergo ultrasonography during their visit with laryngology or speech language pathology.
DIAGNOSTIC_TESTUltrasound for cough
Adult patients who are seen at the Sean Parker Institute for the Voice and are determined to have neurogenic cough for which superior laryngeal nerve block is recommended will undergo this procedure under ultrasound guidance. Patients without neurogenic cough will also be recruited for ultrasound assessment to establish landmarks and normal variation. Patients will be assessed for their comfort with undergoing the procedure and clinicians will be surveyed on the ease and benefit of performing the procedure under ultrasound guidance.
DIAGNOSTIC_TESTUltrasound for vocal fold atrophy or vocal fold paresis/paralysis
Adult patients who are seen at the Sean Parker Institute for the Voice and are determined to have vocal fold atrophy or vocal fold paresis/paralysis for whom injection laryngoplasty is recommended will undergo laryngeal ultrasound prior to the procedure to assess baseline anatomy as well as following the procedure (both immediately following the procedure as well as at follow-up visits) in order to assess the amount of injectate.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Quantitative clinician-reported usability measure of ultrasound during injection of the internal branch of superior laryngeal nerve for neurogenic cough. | Immediately post-intervention | The clinician will use the Likert scale and rate a series of statements on a scale of 1 (strongly disagree) to 5 (strongly agree). The lowest possible total score is 12 (overall clinician disagreement), and the highest possible total score is 60 (overall clinician agreement). |
| Qualitative clinician-reported usability measure of ultrasound during injection of the internal branch of superior laryngeal nerve for neurogenic cough. | Immediately post-intervention | The clinician will respond to the following open-ended questions: * What are the benefits with performing the procedure with ultrasound? * What are the limitations with performing this procedure with ultrasound? |
| Patient comfort measures during ultrasound-guided injection of the internal branch of superior laryngeal nerve for neurogenic cough. | Day 1 | Number of patients that fall into the below categories as determined by the provider care team: * No discomfort: talking/comfortable throughout * Minimal discomfort: 1 or 2 episodes of mild discomfort with no distress * Mild discomfort: More than 2 episodes of discomfort without distress * Moderate discomfort: significant discomfort experienced several times with some distress * Severe discomfort: frequent discomfort with significant distress |
| Time to complete superior laryngeal nerve injection under ultrasound. | Day 1 | The amount of time will be recorded in minutes. |
| Images and descriptors of internal branch of superior laryngeal nerve anatomy and normal variation. | Day 1 | This is a qualitative outcome measure. Providers will provide a description of the internal branch of superior laryngeal nerve anatomy with accompanying images from the strobe. |
| Change in volume of injectate in injection laryngoplasty measured by ultrasound compared to amount injected after procedure and at follow-up. | Immediately post-intervention and at 4 week follow-up visit | The volume will be recorded in mL. |
| Presence, bulk, and function of tongue, suprahyoid, and infrahyoid musculature on ultrasound for patients with and without swallowing complaints. | Day 1 | This is a qualitative outcome measure. Providers will provide a description of the tongue, suprahyoid, and infrahyoid musculature on ultrasound for patients with and without swallowing complaints. |
| Evaluation of suprahyoid musculature on ultrasound for patients with muscle tension dysphonia. | Day 1 | This is a qualitative outcome measure. Providers will provide a description of the suprahyoid musculature on ultrasound for patients with muscle tension dysphonia. |
