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%. CONCLUSION: Ni-Ti shape memory alloy stand can expand the stricture of larynx and trachea quickly and thus improve the breath effectively.
