对 12例喉气管狭窄病人行支撑内固定治疗 ,手术时首先切除喉气管病变 ,松解瘢痕组织 ,局部修复后行扩张治疗 ,方法为 :1用空心管做喉气管内固定扩张 ;2硅橡胶囊喉模软固定支撑 ;3“T”形管置入支撑。支撑扩张时间为 2周～ 18个月。结果 :9例顺利拔管 ;1例带管放疗 1年后拔管 ;1例拔管后肿瘤复发改行半喉切除术 ;1例未支撑 ,带管随访中。认为喉气管狭窄行支撑内固定疗法 ,效果较满意。 12 cases of laryngeal tracheal stenosis patients underwent brace fixation, the first surgical removal of laryngeal tracheal lesions, the release of scar tissue, local repair after dilation treatment, the method is as follows: 1 with hollow tube laryngotracheal tube fixation expansion; 2 silicone rubber Thoracostomy soft fixed support; 3 “T” shaped tube into the support. Support expansion time of 2 weeks to 18 months. Results: 9 cases were successfully extubated; 1 case was extubated after radiotherapy for 1 year; 1 case had recurrence of semicokectomy after extubation; 1 case was unsupported and the tube was followed up.
