title: [The treatment of stricture of larynx and trachea with Ni-Ti shape memory alloy stand].
abstract: OBJECTIVE
  To evaluate the use of Ni-Ti shape memory alloy stand in the treatment of stricture of larynx and trachea.
  
  
  METHODS
  The clinical materials of 14 patients were analyzed. All patients had stricture of larynx and trachea and accepted the treatment with Ni-Ti shape memory alloy stand.
  
  
  RESULTS
  All patients breathed freely after the operation, and the trachea fistula was closed at the time of operation. The follow-up survey for these patients lasted for 2 to 12 months. None of the patients had signs of the stricture of the respiratory tract. The short-term effective rate was 100%.
  
  
  CONCLUSIONS
  Ni-Ti shape memory alloy stand can expand the stricture of larynx and trachea quickly and thus improve the breath effectively. It can be used as a routine method in the treatment of stricture of larynx and trachea.
