[Application of CO2 laser and T tube in the treatment of the laryngeal stenosis].

OBJECTIVE

To introduce a new method for treating laryngeal stenosis of both children and adults using silicon T tube and CO2 laser.

METHODS

Twenty-two cases stenosis of adults and children were treated with silicon T tube and CO2 laser. The tracheotomy were enlarged upward, the laryngeal cavity scar was removed by using CO2 laser and the laryngeal cavity was exposed by distending laryngoscope under general anesthesia. The follow up time is between 1 to 3 years.

RESULTS

The 22 cases were successfully decanulated postoperatively in 12 to 24 months. Silicon 4 cases's T tube were either too high or too low and had second operation.

CONCLUSION

The method for treating laryngeal stenosis of both children and adults using silicon T tube and CO2 laser are effective, easy to operate, less invasive and have a short recovery interval.
