Four or more years after recurrent laryngeal nerve section for adductor spastic dysphonia, 25 patients assessed their voice quality and phonatory effort in relation to presurgical status, using categorical ratings (gradations of better or worse, and of easier and harder) and also numerical ratings. Quality was judged better by 88%, and effort easier by 84%; but many thought the improvement was only moderate or slight. Three speech pathologists, assessing presurgical and current recordings of the patient's voices numerically, rated the majority of the better and easier voices much closer to their presurgical status than to normal. Clinicians were highly consistent and reliable in their assessments. Patients were often in disagreement with clinician ratings and generally rated their dysphonia as less severe than the clinicians did. These discrepancies are discussed within the context of contradictory opinions regarding the efficacy of recurrent laryngeal nerve section for the treatment of adductor spastic dysphonia.
在因内收肌痉挛性发音障碍行喉返神经切断术后四年或更长时间，25名患者根据术前状况评估了他们的嗓音质量和发声努力程度，采用了分类评分（更好或更差、更容易或更难的等级）以及数字评分。88%的患者认为嗓音质量有所改善，84%的患者认为发声努力程度变容易了；但许多人认为改善只是中等程度或轻微的。三名言语病理学家对患者术前和当前的嗓音录音进行数字评分，结果显示，大多数嗓音改善且发声变容易的患者，其嗓音状况更接近术前水平，而非正常水平。临床医生的评估具有高度的一致性和可靠性。患者常常与临床医生的评分意见不一致，总体上对自己发音障碍严重程度的评估低于临床医生。本文在关于喉返神经切断术治疗内收肌痉挛性发音障碍疗效的矛盾观点背景下，对这些差异进行了讨论。
