Ankylosis of the cricoarytenoid joints due to rheumatoid arthritis (RA) may cause upper airway obstruction by fixation of the vocal cords in the midline. In early stages, this condition usually results in minor symptoms which are easily overlooked. It may, however, very rapidly, e.g., in association with an upper respiratory tract infection, become life-threatening. It is essential to diagnose this condition early to avoid emergency situations. In 5 patients with classic RA and in one patient with juvenile RA severe laryngeal obstruction was operated on using a new simple technique consisting of a mobilization of the arytenoid cartilages and laterofixation of one of the vocal cords.
类风湿性关节炎（RA）导致的环杓关节强直可能会因声带固定于中线位置而引起上呼吸道梗阻。在早期阶段，这种情况通常只会导致一些容易被忽视的轻微症状。然而，它可能会非常迅速地，例如在合并上呼吸道感染时，变得危及生命。早期诊断这种情况对于避免紧急情况至关重要。在5例典型RA患者和1例青少年RA患者中，采用一种新的简单技术对严重的喉梗阻进行了手术，该技术包括杓状软骨活动术和一侧声带的外侧固定术。
