A corre？？o das estenoses traqueobr？nquicas mediante o emprego de órteses

the surgical treatment of patients with tracheobronchial stenosis requires individualized attention due to the complexity of its origin though tracheoplasty is considered to be the ideal procedure. the most common causes of stenosis are tracheal intubation and the development of neoplasias. these are the very conditions that most benefit from endoscopic treatment when surgical correction is not indicated. today, endoscopic procedures include the application of different kinds of laser and dilators usually delivered with a rigid bronchoscope, as well as radiotherapy and stents that may be used separately or associated. basically, there are two types of stents, metal or silicone. the metallic ones are more frequently indicated in cases of tracheomalacia and extrinsic compressive stenosis. silicone are more applicable in cases of tracheobronchial obstruction resultant from acute inflammation or endoluminal tumor. although these methods can be used interchangeably in some cases, the best way to correct tracheobronchial stenosis is to correctly decide upon the treatment as early as the preliminary steps.
