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.
对两组接受二氧化碳激光治疗（n = 23）和声门裂开声带切除术（n = 21）治疗T1a期声门癌的男性患者进行了视频喉镜频闪检查、心理声学和频谱分析，以评估其发声功能。所有患者均非职业用嗓。本研究揭示了解剖特征与嗓音质量之间存在良好的相关性。心理声学和频谱分析显示，声门裂开手术治疗的患者功能结果明显较差（p < 0.003）。在该组中，视频喉镜频闪检查显示，双侧室带的代偿率高于激光治疗组（p < 0.02）。作者得出结论，声带切除术后获得的功能结果取决于瘢痕形成模式与室带或声带代偿性运动亢进的各种组合。激光声带切除术后获得更好的解剖和功能结果，这可能是因为此类手术能带来更好、更快的愈合过程。
