[A phoniatric treatment report for a dysphonia case with unilateral false cord bulging]

This case report was a 43-year-old male with phonation problem described as hoarseness, reduced loudness and with effort. Patient was examined by a laryngologist and a voice-speech pathologist. The laryngeal finding showed left false cord bulging under indirect laryngoscope and fiberscope. Patient's dysphonia was analyzed from perceptual and acoustic parameters. Patient was diagnosed as dysphonia with left cord bulging and under a phoniatric treatment. The goal of treatment was to eliminate vocal abuse and misuse behaviors, stimulate true cords function by Boone's "inhalation phonation" method then reduce compensatory behaviors of false cord involvement and balance life between work and after work. The results after the phoniatric treatment and underlying phonation mechanism were presented and discussed.
