CO2激光结合改良T型管植入术治疗喉狭窄

目的 研究CO2激光技术结合放置T型硅胶管治疗成人及儿童喉狭窄的治疗效果。方法 全身麻醉支撑喉镜下CO2激光切除喉内瘢痕，扩大气管造口向上引置T型硅胶管，治疗成人及儿童喉狭窄患者22例，随访1～3年。结果 22例患者在12～24个月后经检查拔除T型管，其中2例T型管位置放置过高和2例T型管的位置过低，再次手术重新放置T型管。结论 应用CO2激光技术结合放置T型硅胶管治疗成人及儿童喉狭窄具有治疗效果好、创伤小、操作简便和术后恢复快等优点。

Application of CO2 laser and T tube in the treatment of the laryngeal stenosis]

OBJECTIVE: To introduce a new method for treating laryngeal stenosis of both children and adults using silicon T tube and CO2 laser. METHODS: Twenty-two cases stenosis of adults and children were treated with silicon T tube and CO2 laser. The tracheotomy were enlarged upward, the laryngeal cavity scar was removed by using CO2 laser and the laryngeal cavity was exposed by distending laryngoscope under general anesthesia. The follow up time is between 1 to 3 years. RESULTS: The 22 cases were successfully decanulated postoperatively in 12 to 24 months. Silicon 4 cases's T tube were either too high or too low and had second operation. CONCLUSION: The method for treating laryngeal stenosis of both children and adults using silicon T tube and CO2 laser are effective, easy to operate, less invasive and have a short recovery interval.
