Upper airway obstruction due to bilateral vocal cord paralysis was successfully relieved by carbon dioxide laser posterior cordectomy. All patients achieved satisfactory airway and decannulation. Flow-volume loop spirograms obtained preoperatively and postoperatively documented improved flow rates on inspiration and expiration. Final voice quality was subjectively good in all patients. Follow-up has ranged from 1 year 10 months to 5 years 8 months, and initial improvement has been sustained in all cases. Carbon dioxide laser posterior partial cordectomy is an alternative management option for relief of upper airway obstruction due to bilateral vocal cord paralysis. The procedure can be performed without prophylactic tracheotomy. Subjectively good voice quality is preserved.
二氧化碳激光后索切除术成功缓解了双侧声带麻痹所致的上气道梗阻。所有患者均实现了满意的气道状况并拔除了气管套管。术前和术后获得的流量-容积环呼吸描记图显示吸气和呼气时流速均有所改善。所有患者的最终嗓音质量主观上良好。随访时间为1年10个月至5年8个月，所有病例的初始改善情况均得以维持。二氧化碳激光后索部分切除术是缓解双侧声带麻痹所致上气道梗阻的一种替代治疗选择。该手术无需预防性气管切开即可进行。可保留主观上良好的嗓音质量。
