A clinical evaluation of CO2 laser endoscopic bilateral posterior wedge-shaped cordectomy (EBPC) in patients with severely compromised airway due to bilateral paralysis of the vocal fold.
The CO2 laser EBPC was performed in four cases of bilateral vocal cord paralysis. Follow-up has ranged from five months to 36 months.
Three patients achieved satisfactory airway after one laser procedure and one patient received second laser operation to manage her posterior webbing. Final voice quality was subjectively good in all patients.
The authors' data confirm the safety, ease of performance, and efficiency of the CO2 laser EBPC in patients with bilateral vocal fold paralysis. The advantages of the procedure are simplicity in concept, reliability of outcome, no need for prophylactic tracheotomy, low risk of complications, adequate airway and good voice preservation. CO2 laser endoscopic bilateral posterior wedge-shaped cordotomy is an alternative management option for relief of upper airway obstruction due to bilateral vocal cord paralysis in abduction. The procedure is worthy to apply in clinical use.
对因双侧声带麻痹导致气道严重受损的患者进行二氧化碳激光内镜下双侧后楔形声带切除术（EBPC）的临床评估。
对4例双侧声带麻痹患者实施了二氧化碳激光EBPC。随访时间为5个月至36个月。
3例患者在一次激光手术后气道状况令人满意，1例患者接受了第二次激光手术以处理其后部粘连。所有患者的最终嗓音质量主观上良好。
作者的数据证实了二氧化碳激光EBPC在双侧声带麻痹患者中的安全性、操作简便性和有效性。该手术的优点包括概念简单、结果可靠、无需预防性气管切开、并发症风险低、气道通畅且嗓音保留良好。二氧化碳激光内镜下双侧后楔形声带切开术是缓解双侧声带麻痹外展所致上气道梗阻的一种替代治疗选择。该手术值得在临床中应用。
