Measurement of the mechanical properties of the human vocal fold in vivo makes it possible to clarify the physiological, or pathophysiological aspect of the voice-emittance mechanism. This study is concerned with the resonance frequencies of both vocal folds with unilateral vocal fold polyp, recurrent laryngeal nerve paralysis and glottic cancer which may cause a right-and-left difference of the mechanical properties of the vocal folds.A compulsory vibration was induced to the vocal fold by pressing a vibrator on the midline of the thyroid cartilage. The vocal fold vibration, thus created, was measured and recorded as a function of frequencies and Q-values of the resonance by using the Ultrasonic Pulse Method.The resonance frequencies observed are: (1) f=118.1±12.0Hz for the vocal fold with polyp and f=131.8±11.9Hz for the healthy side, (2) f=134.5±16.9Hz for the vocal fold with cancer and f=118.5±12.4Hz for the other side, and (3) f=106.1±20.0Hz for the vocal fold with recurrent laryngeal nerve paralysis and f=124.3±20.7Hz for the other.No significant differences are observed in Q-values between the sick and healthy sides in all three diseases.Theoretically, the resonance frequency of the vocal fold is determined by its mass and stiffness. Decreased resonance frequency of the vocal fold with polyp in comparison with healthy side is considered to be an effect of increased mass. Increased resonance frequency of the vocal fold with cancer in comparison with healthy side is due to increased stiffness. Decreased resonance frequency of the vocal fold with recurrent laryngeal nerve paralysis in comparison with healthy side can be the result of decreased stiffness.
