Abstract：
BACKGROUND: Subglottic tracheal stenosis is stenosis of the trachea between the vocal cords and the lower margin of the cricoid cartilage. The Montgomery T-tube is used as a tracheostomy tube and a combined tracheal stent to avoid postoperative tracheal stenosis.
METHODS: Because the stenosis is close to the glottis, surgical treatment is complex, and many complications may arise.
METHODS: Subglottic tracheal stenosis.
METHODS: The patients underwent endotracheal intubation or tracheotomy because of acute pancreatitis, laryngeal malignancy, or cerebral hemorrhage after endotracheal intubation or tracheotomy and presented with varying degrees of tracheal stenosis and dyspnea. We relieved airway stenosis and improved dyspnea in these 3 patients by placing a Montgomery T-tube.
RESULTS: None of the 3 patients had intraoperative complications. In 2 of the cases, airway secretions were stored after surgery.
CONCLUSIONS: Montgomery T-tube placement is safe and effective for patients with complex subglottic tracheal stenosis.

摘要：
背景：声门下气管狭窄是指声带与环状软骨下缘之间的气管狭窄。蒙哥马利T型管用作气管造口管和组合式气管支架，可避免术后气管狭窄。
方法：因为狭窄靠近声门，手术治疗复杂,可能会出现许多并发症。
方法：声门下气管狭窄。
方法：因急性胰腺炎行气管插管或气管切开的患者，喉恶性肿瘤,或气管插管或气管切开术后脑出血，并表现为不同程度的气管狭窄和呼吸困难。我们通过放置MontgomeryT形管缓解了这3例患者的气道狭窄并改善了呼吸困难。
结果：3例患者无术中并发症。在两种情况下，手术后保存气道分泌物。
结论：MontgomeryT管置入术对于复杂声门下气管狭窄患者是安全有效的。
