Eligibility
Inclusion criteria
Inclusion criteria: 1. Airway stenosis occurs after oral/nasal tracheal intubation or tracheotomy intubation; 2. Hyperplastic tissues such as granulation tissue hyperplasia and fibroplasia grow into the trachea lumen, resulting in airway stenosis; 3. Continued holmium laser cryoablation under bronchoscope was performed.
Exclusion criteria
Exclusion criteria: 1. Airway stenosis mainly caused by tracheal softening, collapse, scar contraction, etc., with no hyperplasia in the tracheal lumum; 2. The endotracheal intubation cannot be removed after ablation, and the endotracheal intubation still needs to be retained for a long time, which affects the observation of ablation efficacy; 3. After ablation, the patient refused bronchoscopy or CT examination for various reasons, or lost follow-up.
