[The progress of clinical research on the causes and treatments of pediatric laryngotracheal stenosis].

Pediatric laryngotracheal stenosis is a refractory disease in the present otorhinolaryngological head and neck surgery, including congenital stenosis caused by laryngotracheal deformities and acquired stenosis. The incidence of congenital laryngotracheal malformation has a rising trend.But acquired stenosis is still more common,which is mostly caused by iatrogenic injury (e.g. endotracheal intubation and tracheotomy).So prevention and early intervention are very important.and the standardization of the endotracheal intubation and tracheotomy operation and follow-up care are necessary. The treatments and recovery of pediatric laryngotracheal stenos is more complex and difficult than adults. Operation method is varied, and appropriate treatment plan depends on the degree of stenosis, position as well as the general condition.
