A report is given about one patient with bilateral paralysis of the vocal cords. After local anesthesia of the piriform sinus and novocain blockade of the R. externus of the superior laryngeal nerve of the same side a widening of the glottis and an improvement of the respiration was observed. After section of the R. externus of the superior laryngeal nerve we could observe even an improvement of the same effect as it has been observed after local anaesthesia. These observations were proved by spirography and photo-documentation. Because of paradox movements of the vocal cords a narrowing of the glottis was observed during inspiration. Therefore the patients dyspnea did not improve to the extent as it could be expected from the widening of the glottis after this therapy. The problems are discussed in relation to the literature.
报告了1例双侧声带麻痹患者。在梨状窝局部麻醉并对同侧喉上神经外支进行奴夫卡因阻滞之后，观察到声门增宽，呼吸改善。在切断喉上神经外支之后，我们甚至观察到与局部麻醉后相同的效果改善。这些观察结果通过呼吸描记法和摄影记录得到证实。由于声带的反常运动，吸气时观察到声门变窄。因此，患者的呼吸困难并未改善到该治疗后声门增宽所预期的程度。结合文献对这些问题进行了讨论。
