On clinical services in this department, we manage disorders of oral cavity, salivary glands, tonsils, swallowing functions, pharynx, larynx, voice and obstructive sleep apnea. We also put equal emphasis on basic researches of the above disorders to keep the state of the art. Our research interests are focused on the phonation and swallowing functions of the larynx, especially investigating the phonation function of the vocal folds using non-invasive measurements. The quality of voice depends largely on the mechanical characteristics of the cover, e.g., evenness, viscosity and elasticity of the tissues. Any changes in the mechanical properties that hinder the production of a regular mucosal wave will perturb the sound wave and aggravate the symptoms of dysphonia. Establishing non-invasive quantitative assessments of the vocal folds function is the goal that voice clinicians have long searched for. We tried to use ultrasound imaging and measure phonation threshold pressure during normal phonation to estimate the phonation function of the vocal folds.
