作者应用环状软骨前裂开,肋软骨移植一期喉气管成形(OS-LTP),治疗较大儿童严重声门下狭窄13例。方法:经气管切开套管全麻。自鼻孔经喉插入一鼻气管导丝。在气管造瘘口处做一水平弧形切口,暴露喉部自前联合下方向下经环状软骨、气管环至气管瘘口做一垂直切口。取适当长和宽肋软骨备用。对需环状软骨后板裂开的病例,截一小段软骨插入裂口处。用6-0 vicryl线缝合固定,通过预置鼻气管导丝,导入适当大小的鼻气管插管至气管
The authors applied anterior lobe of annular cartilage and costal cartilage transplantation for laryngotracheal tube (OS-LTP) in the treatment of severe subglottic stenosis in 13 children. Methods: Tracheotomy cannula general anesthesia. Insert a nasotracheal tube guidewire from the nostril through the throat. In the tracheostomy stoma at a horizontal arc incision, exposing the throat below the joint from the previous down through the cricoid cartilage, tracheal ring to the tracheal fistula to make a vertical incision. Take appropriate long and wide costal cartilage reserve. On the need for annular lobe cracked cases, a small section of cartilage inserted into the gap. Sutured with 6-0 vicryl wire, and a nasotracheal tube was cannulated to the trachea
