Abstract
Phonatory function following no smoking period for longer than two months was evaluated in 6 patients who had been diagnosed the polypoid vocal fold with Yonekawa classification type I. The results are summarized as follows: 1) Habirual FO (Pitch) tended to be high and FO range tended to be wide in aerodynamic tests. 2) Grade and rough factor of hoarseness were improved in psychoacoustic evaluation. 3) Amplitude of bilateral vocal folds became normal in stroboscopic examination. 4) The edematous lesions of bilateral vocal folds were markedly improved in fiberscopic finding of the larynx. Therefor, in a case with slight edematous lesions of the polypoid vocal fold, follow up with only no smoking is available at least for two months.
