Résumé
Phonation threshold pressure (P In vivo animal study. In an in vivo canine phonation model, laryngeal adductor muscles were activated together by stimulation of the recurrent laryngeal nerves (RLNs) and individually via stimulation of respective terminal nerve branches. Cricothyroid (CT) muscles were activated via stimulation of the superior laryngeal nerves. ILMs were activated in a graded manner at various combinations as transglottal airflow was gradually increased. Aerodynamic and glottal posture parameters were measured at phonation onset. Graded RLN stimulation decreased glottal distance and increased P The effects of ILM activation on P NA, basic science Laryngoscope, 132:1427-1432, 2022.
