Abstract:Objective To observe the effect of interventional treatment of children with subglottic cicatricial stenosis, summarize the successful treatment experience, and discuss the application value of pediatric respiratory interventional technology in children with subglottic cicatricial stenosis.Methods The clinical data of 23 children with subglottic cicatricial stenosis from December 2017 to December 2020 were retrospectively analyzed. Among them, there were 14 males and 9 females, aged 28 d ~ 8 years old. All patients had a history of endotracheal intubation and had severe respiratory dyspnea after extubation, which was confirmed by laryngoscopy or bronchoscope and then treated with respiratory intervention. Use tracheotomy as a preplan to ensure patency of breathing.Results In this study, there were 3 cases with stenosis degree of 75% ~ 90%, 20 cases with stenosis degree greater than 90%, and the stenosis length of all cases was less than 1 cm. The previous 4 cases underwent simple balloon dilation for 4 times, but due to poor efficacy, the patients were changed to comprehensive respiratory interventional therapy, such as holmium laser therapy, clamp therapy, balloon dilation therapy, cryotherapy, and finally cured. The last 19 cases were treated with the above comprehensive respiratory intervention techniques directly, and the results were all cured.Conclusion Balloon dilation is effective in the treatment of subglottic cicatricial stenosis caused by tracheal intubation, but the long-term effect is not good. The application of thermal therapy, clip therapy, balloon dilation therapy, cold therapy and other comprehensive interventional therapy, the therapeutic effect is stable, the cure rate is high, the safety is high.
