目的研究自制喉扩张管治疗外伤性喉气管狭窄的治疗效果,探讨放置喉扩张管的时限。方法62例外伤性喉气管狭窄患者,分为两组。第一组52例,为初次行喉扩张管治疗的患者。第二组10例,为行喉扩张管治疗失败后再次行喉扩张管治疗的患者。气管插管全身麻醉下行颈前正中喉气管切开,尽量切除喉气管内瘢痕组织,置入喉扩张管。结果第一组患者术后9-12个月全部拔除喉扩张管,呼吸通畅,发音较好,劳动力恢复。第二组患者拔管后3-4个月出现再狭窄,再次行喉扩张管治疗后顺利拔管,带管期间无严重并发症,如呼吸道阻塞的发生。随访1-10年,来发现再次喉气管狭窄患者。结论自制喉扩张管制作简单、方便,治疗效果良好,无排斥反应。喉扩张管的留置时间至少应在9-12个月以上。
Objective To study the therapeutic effect of self-made laryngeal dilatation tube in the treatment of traumatic laryngotracheal stenosis and to explore the time limit for laryngeal dilatation tube placement. Methods Totally 62 patients with traumatic laryngotracheal stenosis were divided into two groups. The first group of 52 patients, for the first line of laryngeal dilation tube treatment of patients. The second group of 10 cases, for the treatment of laryngeal dilatation of the tube after the failure of throat dilation tube treatment again. Tracheal intubation General anesthesia in the middle of the neck before tracheotomy, as far as possible removal of laryngeal tracheal scar tissue, into the throat dilation tube. Results In the first group of patients, the laryngeal dilation tube was removed all the time after 9-12 months, breathing was smooth, the sound was better, and the labor force recovered. The second group of patients with restenosis 3-4 months after extubation, throat dilatation tube again after successful extubation, no serious complications during the tube, such as the occurrence of airway obstruction. Follow-up 1-10 years, to find patients with recurrent laryngeal tracheal stenosis. Conclusion Self-made laryngeal dilation tube is simple and convenient, and has good curative effect and no rejection. Throat dilatation catheter retention time should be at least 9-12 months.
