    Area of Science:

    • Pulmonology
    • Laser Surgery
    • Oncology

    Background:

    • Airway obstruction presents a significant clinical challenge requiring effective treatment modalities.
    • Carbon dioxide (CO2) lasers offer precise tissue ablation through intense heat generation.

    Purpose of the Study:

    • To evaluate the efficacy and safety of CO2 laser treatment for various causes of airway obstruction.
    • To assess the outcomes of laser therapy in patients with benign and malignant airway lesions.

    Main Methods:

    • A rigid bronchoscope equipped with a CO2 laser (10.6 µm wavelength) was utilized.
    • Treatment was administered to 18 patients aged 21-62 with conditions including tracheal stenosis, granulation tissue, adenoma, webs, and carcinoma.
    • Patient outcomes were assessed based on airway improvement and complication rates.

    Main Results:

    • Fifteen out of 18 patients experienced good outcomes, with all patients demonstrating improved airway patency post-treatment.
    • The best results were achieved in patients with benign, inflammatory airway diseases.
    • Laser treatment was associated with minimal bleeding, edema, and scar formation.

    Conclusions:

    • CO2 laser therapy is a viable option for managing diverse airway obstructions, providing significant functional improvement.
    • The procedure offers advantages such as reduced hemorrhage and tissue reactivity compared to conventional methods.
    • Key limitations include the cost of equipment, requirement for general anesthesia, and the necessity for direct visualization.
