Malignant airway stenosis generally refers to airway lumen stenosis caused by various primary and metastatic malignant tumors and restricted airflow, which can be manifested as dyspnea to varying degrees or even asphyxia and death. It seriously affects the quality of life of patients with airway stenosis. With the continuous development of bronchoscope interventional techniques, various interventional therapies such as ablation, dilation and stent implantation can be used to reventilate the airway. Among them, ablation treatment is the most commonly used method. The methods of ablation treatment include cold, heat, photodynamic, local chemoradiotherapy, etc. This article will review the new applications of various methods used in the ablation treatment of malignant airway stenosis progress.
