An objective test of the efficacy of recurrent nerve section in the treatment of spastic dysphonia was conducted with partially trained observers in a blind rating task. It was found that, although immediate effects of the surgery as measured by a general communication effectiveness instrument could not be established, long-term (1-yr post-surgery) effects did emerge and at a high level of confidence. The results corroborate subjective judgments of the effectiveness of the Dedo procedure.
在一项盲评任务中,由部分经过培训的观察者对喉返神经切断术治疗痉挛性发声障碍的疗效进行了客观测试。结果发现,尽管通过通用沟通有效性工具衡量的手术即时效果未能得到证实,但长期(术后1年)效果确实出现了,且具有高度的可信度。这些结果证实了对德多手术有效性的主观判断。
