Phonosurgery is an effective treatment for some vocal fold pathologies, and the Voice Handicap Index (VHI) survey has been shown to be a useful instrument for evaluating treatment effectiveness. We conducted a nonrandomized, prospective study of 21 patients who underwent phonosurgery for the treatment of non-neoplastic vocal fold lesions at our academic tertiary-care referral center. Our goals were to compare pre- and postoperative VHI scores (subjective assessments) and pre- and postoperative results of acoustic and aerodynamic tests (objective assessments). We sought to determine if there was any correlation between the subjective and objective findings. We looked for differences between professional voice users (n = 10) and nonprofessional voice users (n = 11) in both subjective and objective measures. We found statistically significant differences between pre- and postoperative values in three of four VHI parameters, but in only one of 13 objective measures. There was no correlation between preoperative VHI scores and preoperative acoustic and aerodynamic test results. The professional voice users expressed greater postoperative improvement as reflected by lower VHI scores than did the nonprofessional voice users, confirming that the former are more negatively affected by a voice disability.
嗓音外科手术是治疗某些声带病变的有效方法，嗓音障碍指数（VHI）调查已被证明是评估治疗效果的有用工具。我们在我们的学术三级医疗转诊中心对21例接受嗓音外科手术治疗非肿瘤性声带病变的患者进行了一项非随机前瞻性研究。我们的目标是比较术前和术后的VHI评分（主观评估）以及声学和空气动力学测试的术前和术后结果（客观评估）。我们试图确定主观和客观结果之间是否存在任何相关性。我们在主观和客观测量方面寻找专业嗓音使用者（n = 10）和非专业嗓音使用者（n = 11）之间的差异。我们发现，在四个VHI参数中的三个参数中，术前和术后值存在统计学上的显著差异，但在13项客观测量中只有一项存在显著差异。术前VHI评分与术前声学和空气动力学测试结果之间没有相关性。与非专业嗓音使用者相比，专业嗓音使用者术后VHI评分更低，表明术后改善更大，这证实了前者受嗓音障碍的负面影响更大。
