The quality of voice after radiotherapy is generally considered to be better than that after surgery for early glottic (T1a and T1b) carcinomas. Studies concerning voice quality after radiotherapy are scarce, and results have been contradictory concerning actual normalization of voice following therapy. This study was designed to compare several voice parameters of patients successfully treated 1-12 years previously with radiotherapy (5750-7000 cGy) for early glottic carcinoma. Parameters involved an age- and sex-matched control group. Results showed that voice quality following radiotherapy was less than normal for maximum vocal intensity, dynamic vocal intensity range, jitter, and mean fundamental frequency. These findings showed that voice following radiotherapy could not be considered normal.
对于早期声门型（T1a和T1b）癌，放疗后的嗓音质量通常被认为优于手术治疗后的嗓音质量。关于放疗后嗓音质量的研究较少，并且对于治疗后嗓音的实际恢复正常情况，研究结果相互矛盾。本研究旨在比较1至12年前成功接受放疗（5750 - 7000 cGy）治疗的早期声门型癌患者的几个嗓音参数。参数涉及年龄和性别匹配的对照组。结果显示，放疗后的嗓音质量在最大发声强度、动态发声强度范围、抖动和平均基频方面低于正常水平。这些发现表明，放疗后的嗓音不能被认为是正常的。
