Abstract: Laryngeal stridor is caused by a variety of causes，often accompanied by a variety of clinical manifestations and clinical symptoms，and the causes include not only laryngopharyngeal diseases，but also subglottic and tracheal lesions. Therefore，the thin and soft flexible bronchoscopy can evaluate and diagnose the laryngeal stridor comprehensively. In this paper，laryngomalacia and other 13 diseases were diagnosed by the flexible bronchoscopy according to the anatomical sites. With the rapid development of interventional pulmonology，the bronchoscope interventional techniques such as ablation，balloon dilatation and stenting have provided minimally invasive therapy for laryngeal stridor. In the future，with more and more pediatric respiratory interventional doctors paying attention to the diagnosis and treatment of laryngopharyngeal lesions，the diagnosis and treatment level of laryngeal stridor will be greatly improved.
