ABSTRACT
Videolaryngostroboscopy, psychoacoustic and spectrographic analyses were performed to evaluate vocal function in two groups of male patients who had undergone CO2Laser (n = 23) and laryngofissure cordectomy (n = 21) for the treatment of T1a glottic carcinoma. None of the patients used their voices professionally. This study revealed a good correlation between the anatomical features and voice quality. Psychoacoustic and spectrographic analysis showed that the functional results were significantly worse in the patients treated by laryngofissure (p < 0.003). In this group videolaryngostroboscopy showed a higher rate of compensation in both ventricular folds than shown in the laser-treated group (p < 0.02). The authors conclude that the functional results obtained after cordectomy depend on the various combinations of scarring patterns and compensatory hyperkinesia of the ventricular or vocal folds. The better anatomical and functional results achieved following laser cordectomy may be explained by the fact that such procedures result in better, more rapid healing processes.
