| Objective:To explore the etiology,treatment and extubation of laryngotracheal stenosis after laser or open surgery in patients with laryngeal cancer,thus to raise awareness of laryngotracheal stenosis after laryngeal cancer surgery,and to guide treatment strategies.Methods:A retrospective study.33 patients suffering from laryngotracheal stenosis after laryngeal cancer surgery were selected,from January 2013 to December 2020.These patients were treated with different methods,according to the general condition and etiology,length,degree,location of laryngotracheal stenosis.14 patients underwent CO2laser scar resection of laryngoscope,3 patients underwent balloon dilatation with laryngoscope,6patients underwent T-tube implantation of larynx split,10 patients underwent laser scar resection and balloon dilatation.All patients were followed up for 3 months to 8 years,recorded the diagnosis and treatment,the number of operations and the time of extubation.Results:Of the 33 patients,17 patients were cured by one operation,2 patients were cured by two operations,and 1 patient for 3 times.13 patients were still with tube after one or multiple operations.The rate of extubation was61%.Conclusion:For patients with laryngeal cancer surgery,it is essential to obey the operation classification system and fellow the indications of radiotherapy,prevent pneumonia and upper respiratory tract infection,and treat gastroesophageal reflux.For patients with laryngotracheal stenosis after laryngeal cancer surgery,the reasons,location,length and degree of stenosis should be clarified,thus the best operation plan can be made according to the comprehensive situation.And the rate of extubation and the quality of life of the patients are supposed to be improved.Meanwhile,for these patients,the function of voice,breath and swallowing should be systematically and objectively evaluated,and the data should be collected and recorded,which will lay a foundation for the future clinical research,so as to provide guidance for the treatment of patients with laryngotracheal stenosis after laryngeal cancer surgery. |
