Flexible CO2 Laser Treatment for Subglottic Stenosis.

Objectives: To assess the efficacy and safety of flexible fiber CO2 laser surgery for subglottic stenosis and to present retrospective experience of 14 patients treated with flexible fiber CO2 laser system. To determine the characteristics, management protocols, prognostic factors, and postoperative outcomes of the sample.

Methods: Retrospective review of patients with subglottic stenosis undergoing flexible fiber CO2 laser surgery at the tertiary medical center. All demographic and clinical data were collected, radiologic and endoscopic evaluations were performed to assess the characteristics of stenosis. Myer-Cotton grading scale was used for classification of stenotic area.

Results: All patients have subglottic stenosis due to intubation-related causes and inappropriate tracheostomy procedure. The duration of intubation period ranged from 15 days to 4 years; 11 patients have grade III stenosis according to Myer-Cotton system and there was cricoid involvement in 2 patients. The mean follow-up period was 5.2 months and postoperative decannulation was achieved in 10 patients (71.4%).

Conclusions: Subglottic stenosis is the difficult situation to manage minimal invasively. Flexible fiber CO2 laser surgery is safe and effective in the management of properly selected patients and can be used as a first option for patients.
