Due attention does not seem to have been paid to the problem of vocal cord stiffness in dysphonia, because it is extremely difficult to assess and to treat. Four illustrative cases are presented where the stiffness deviation was apparently involved in the dysphonia and successfully treated by laryngeal framework surgery. A breathy, high-pitched, and strained voice may be suggestive of very stiff vocal cords. Manual pressure on the thyroid cartilage in various manners during phonation can provide us with useful information about the stiffness of the cords, and indication for surgery. Surgical A-P shortening of the thyroid ala reduces the stiffness, while cricothyroid approximation increases it.
由于声带僵硬在发音障碍中极难评估和治疗，因此这一问题似乎未得到应有的关注。本文介绍了四个具有代表性的病例，其中声带僵硬偏差显然与发音障碍有关，并通过喉框架手术成功治愈。呼吸音、高音调且紧张的嗓音可能提示声带非常僵硬。在发声过程中以各种方式手动按压甲状软骨可为我们提供有关声带僵硬程度及手术指征方面的有用信息。甲状腺翼的手术性前后缩短可减轻僵硬程度，而环甲肌靠拢则会增加僵硬程度。
