My daughter of 5 years has subglottic stenosis; her wind pipe cross section is reduced by 45%. This is due to intubation during her treatment for pneumonia. Her air way become narrowed when she was intubated for 10 days for her pneumonia. She got laser surgery/therapy but not much improvement. She has noisy breath in normal day time. While sleeping she is ok i. E. No noise breath. Though she is active, she cannot move fast or run or play, if she does so she will be having trouble to breath. If she is infected by flue or cold, she will be having tough time for breathing. So far, we are trying to manage the situation with nebulizer, steam inhaling. Question: any treatment (without surgery) to cure this subglottic stenosis?
