Aims To estimate the efficacy and safety of the straight silicone stent external fixation for the treatment of subglottic stenosis. Method We collected clinical data from 17 patients with subglottic stenosis from January, 2014 to January, *** 18 straight silicone stents were successfully inserted into 17 patients. Dyspnea of 17 patients relieved obviously. Tracheal diameter increased from 3.54±0.59mm to 10.71±1.42mm (t=15.78,P=0.002). Modified medical research council (mMRC) dyspnea scale decreased from 2.0 (1~4) to 0.0 (0~2) (Z=-4.54,P=0.001). 9 patients developed complications include pneumomediastinum (N=1, 5%), granulomas hyperplasia(N=6, 33%), stubborn cough(N=4, 22%), infection(N=2, 11%), bleeding (N=1, 5%) and mucus plugging (N=,5%). All complications were mild and timely managed. There was no stent migration occurring in the follow-up observation. Conclusion The straight silicone stent external fixation is a safe and effective treatment for patients suffered from subglottic airway stenosis.
