【 摘 要 】

STUDY DESIGN: Experimental.METHOD: A mathematical model of the aerodynamic and viscoelastic equations of the larynx, reproducing its anatomic and physiologic characteristics, is proposed to simulate the organ during phonation.AIM: Its objective is to provide a new tool to the discipline of otorhinolaryngology in order to better understand the physical phenomena present in phonation, both in normal and pathologic cases.RESULTS: The obtained results showed several physical phenomena, such as the horizontal and vertical phase difference among the vocal fold surface movements, the formation of negative pressure over the superior portion of the glottis, and vortex formation after the glottal constriction are reproduced by the model. Additionally, theoretical studies about some laryngeal diseases are presented and discussed, suggesting that previous and "virtual" evaluations of surgical interventions will be feasible in the future.
