Aerodynamic Outcomes of Four Common Voice Disorders: Moving Toward Disorder-Specific Assessment

Phonation Quotient Using Three Aerodynamic Instruments in the Disordered Voice

“…Existing reports have found that estimates of airflow using PQ or measures of transglottal airflow are substantially larger in patients with paralysis/paresis compared to those with benign lesions. 5,23 In the present study, across all three instruments the paralysis/paresis group manifested larger PQ measures by approximately 200 mL/s compared to the benign lesion group. This is likely explained by a larger degree of glottal insufficiency in the former group, 5 although glottal gap measurements would be needed to confirm that supposition in the present study sample.…”

Adult normative data for phonatory aerodynamics in connected speech

“…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 . Dastolfo and colleagues found that phonatory aerodynamic outcomes in connected speech demonstrated greater treatment response than phonatory aerodynamics in sustained vowels and repeated consonant vowel stimuli .…”

“…Phonatory aerodynamic measurements are a standard part of the voice laboratory evaluation. 1,2 These measurements have been shown to distinguish normal from disordered voices, determine stimulability for behavioral treatment, and track response to intervention. [3][4][5][6][7] Despite the proven significance of aerodynamic measurements, use of these measures in clinical settings is rare.…”

“…1,12 Dastolfo and colleagues found that phonatory aerodynamic outcomes in connected speech demonstrated greater treatment response than phonatory aerodynamics in sustained vowels and repeated consonant vowel stimuli. 1 However, data on phonatory aerodynamic values in people without voice disorders are lacking in the literature, which makes judgments about the normalcy of findings in disordered populations difficult. The purpose of this study was to establish phonatory aerodynamic normative values in connected speech.…”

Very long‐term Voice Handicap Index Voice Outcomes after Montgomery Thyroplasty: A cross‐sectional study

“…Although VHI‐30 is largely recognised as a valid self‐evaluation tool, correlation between the subjective VHI‐30 and objective acoustic and aerodynamic measures is poor . Therefore, this patient‐centred approach represents a different way of very long‐term assessment.…”
