In longstanding recurrent laryngeal nerve paresis with parmedian fixation of the vocal cord the fine structure of the vocal muscle is surprisingly well preserved. Though there are in part bundles of atrophic muscle fibers and increased connective tissue, the normal ultrastructure of the remaining muscle and of the myelinated nerves remains always intact. It is assumed that the vocal cord is prevented from regaining its motility both by the increased connective tissue which misdirects the nerve fibers and by irreverisble changes of the cricoarytaenoid joint. The results are discussed in relation to attempts of reconstructive surgery of the recurrent laryngeal nerve as well as various problems in the neurophysiology of the laryngeal muscles.
在声带长期反复喉返神经麻痹伴声带正中固定的情况下，声带肌肉的精细结构出人意料地保存完好。尽管部分存在萎缩的肌纤维束和结缔组织增多的情况，但剩余肌肉和有髓神经的正常超微结构始终保持完整。据推测，增加的结缔组织使神经纤维走向错误，以及环杓关节的不可逆变化，共同阻碍了声带恢复其运动能力。结合喉返神经重建手术的尝试以及喉肌神经生理学中的各种问题，对这些结果进行了讨论。
