Cancer developing on a chronic laryngitis or bilateral superficial cancer of vocal cords still pose management problems to surgeons. Double cordectomy presents the inconvenience of opening the larynx in the median line and the need for insertion of a dilating piece removed during a second stage. These disadvantages can be avoided by an extracartilaginous glottectomy by median opening of thyroid cartilage, monoblock ablation of both vocal cords and immediate closure of larynx by lowering of ventricular bands. A wide larynx is obtained with a loud but veiled voice.
在慢性喉炎基础上发生的癌症或双侧声带浅表癌，仍然给外科医生带来治疗难题。双侧声带切除术存在经中线切开喉部的不便之处，以及需要在第二阶段取出扩张片的问题。通过经甲状腺软骨中线切开进行软骨外声门切除术、整块切除双侧声带并通过降低室带立即关闭喉部，可以避免这些缺点。这样可获得一个宽阔的喉部，但声音响亮却含糊不清。
