Impact of vocal fold augmentation and laryngoplasty on dyspnea in patients with glottal incompetence

“…However, none of the patients complained of dyspnea after injection . More recently, VFA resulted in significantly fewer breaths, decreased mean phonatory airflow rate during voicing, and shorter inspiratory flow duration in patients with UVFP following augmentation . Recently, Asik et al found statistical improvement in both the MMRCDS and MBDS following VFA procedures, but spirometry values were unchanged .…”

Adult normative data for phonatory aerodynamics in connected speech

“…Participants were seated at a table directly across from the SLP and instructed to place the PAS mask tightly over the nose and the mouth. Next, participants read the first four sentences of the Rainbow Passage using a comfortable vocal pitch and loudness level . The recording was then deidentified and saved.…”

“…The screen view was then edited to only allow the measurable information. The number of breaths was counted manually by adding each occurrence of negative airflow tracing below the line indicating 0 mL/s of phonatory airflow . The duration of the passage in seconds was also calculated.…”

“…Phonatory aerodynamic measurements can be collected during sustained vowels, consonant‐vowel syllables, and connected speech . Compared to traditional nonspeech tasks (e.g., sustained vowels or consonant‐vowel combinations), connected speech can reveal treatment change across a variety of voice disorders .…”

“…Gartner‐Schmidt and colleagues reported normative data for 20 healthy speakers for a selection of phonatory aerodynamic measurements of connected speech in comparison to aerodynamic measurements of patients with treated and untreated unilateral vocal fold paralysis (UVFP) . All phonatory aerodynamic measures were significantly increased in patients with preoperative UVFP than the healthy speakers.…”
