Objective:
To improve the curative effects of laryngotracheal stenosis.
Method:
Seventy patients treated for laryngotracheal stenosis on the different pathologic condition of the larynx and trachea were retrospectively reviewed. Different operative reconstruction methods were used accordingly.
Result:
Among 70 patients, 65 (92.9) patients succeed in decannulation. The average course of usage of stent was 14.8 days, the average course from operation to decannulation was 82.0 days.
Conclusion:
The choice of surgical procedure must be decided on the pathologic conditions of the larynx and trachea. Eliminating the defect of the mucosa and reconstructing a wide enough airway was the key to improve the curative effect.
