Experimental animal models of traumatic tracheal stenosis

Benign tracheal stenosis is a common disease in interventional pulmonology,which is mainly resulted from exogenous trauma.The establishment of animal models is helpful to study the pathogenesis and treatment of benign tracheal stenosis.Recent studies have been introduced many methods of traumatic tracheal stenosis.This paper reviews the establishment of animal models with tracheal stenosis,based on different animals,experimental period,methods,and research prospect. Key words: Benign tracheal stenosis;  Trauma;  Animal model
