Endoscopic laser resection of early (T1) laryngeal carcinoma has been advocated as an alternative to radiotherapy. Heretofore, the voice characteristics following this procedure have been addressed in only one review, which included patients treated by irradiation and laser resection. We present the first review of voice findings in 22 patients treated only by endoscopic laser resection of their vocal cord carcinomas. Laser resection of selected vocal cord carcinomas produced voice function results acceptable to the patients and was rated by them to be normal to almost normal. Speech pathologists rated the voices to be near-normal to mildly abnormal. Voices after laser resection of vocal carcinoma exhibited a slightly higher fundamental frequency, a decrease in intensity and phonatory duration, and markedly higher laryngeal airway resistance. The percentage of voicing showed little deviation from normal, as did mean percentage of perturbations.
内镜激光切除早期（T1期）喉癌已被提倡作为放疗的替代方法。在此之前，仅在一篇综述中讨论了该手术后的嗓音特征，该综述纳入了接受放疗和激光切除治疗的患者。我们首次综述了22例仅接受声带癌内镜激光切除治疗患者的嗓音结果。对选定的声带癌进行激光切除产生了患者可接受的嗓音功能结果，患者将其评为正常至几乎正常。言语病理学家将嗓音评为接近正常至轻度异常。声带癌激光切除后的嗓音表现出略高的基频、强度和发声时长降低，以及明显更高的喉气道阻力。发声百分比与正常情况偏差不大，微扰平均百分比也是如此。
