The purpose of this study was to evaluate a new surgical method, plastic cordotomy for treatment of bilateral vocal fold immobility.
We used cadaver experiments on 20 larynges to measure the widening of the glottis after bilateral plastic cordotomy. We conducted a prospective study of 21 female patients operated on with bilateral plastic cordotomy.
Bilateral plastic cordotomy enlarged the width of glottis to 9.55 (range, 8.3-10) mm in men and 8.5 (range, 7.4-8.8) mm in women and the area of glottis to 110.5 mm(2) (range, 88-149 mm(2) ) in men and to 84.5 mm(2) (range, 59-107 mm(2) ) in women. Clinical study revealed that the mean of peak inspiratory flow increased from 1.09 (0.41) L/seconds before surgery to 2.85 (0.67) L/seconds in long-term.
Plastic cordotomy is an effective, anatomically based method to alleviate obstruction in bilateral vocal fold immobility patients. The main advantage of plastic cordotomy is long-term stability of results due to prevention of restenosis.
本研究旨在评估一种新的手术方法，即塑料声带切开术治疗双侧声带固定不动。
我们使用 20 个喉标本进行尸体实验，以测量双侧塑料声带切开术后声门的宽度。我们对 21 例接受双侧塑料声带切开术的女性患者进行了前瞻性研究。
双侧塑料声带切开术使男性的声门宽度扩大至 9.55（范围 8.3-10）mm，女性扩大至 8.5（范围 7.4-8.8）mm，男性声门面积扩大至 110.5mm(2)（范围 88-149mm(2)），女性扩大至 84.5mm(2)（范围 59-107mm(2)）。临床研究表明，吸气峰流量的平均值从术前的 1.09（0.41）L/秒增加到长期的 2.85（0.67）L/秒。
塑料声带切开术是一种有效、基于解剖学的方法，可缓解双侧声带固定不动患者的阻塞。塑料声带切开术的主要优点是由于预防再狭窄，结果具有长期稳定性。
