Background:

The tracheoscope is a modified bronchoscope lacking distal ventilating ports.
It has a long history of use in diagnostic and therapeutic procedures within the subglottis and trachea.

Purpose of the Study:

To highlight the utility of the tracheoscope in managing subglottic and tracheal disorders.
To emphasize its role in enabling safe endoscopic laser procedures.

Main Methods:

Utilizing the closed-tube tracheoscope for maintaining airway control under continuous anesthesia and ventilation.
Employing flexible fiber-directed lasers (e.g., potassium-titanyl phosphate laser) for tissue resection or vaporization.
Implementing smoke evacuation for a safe operative environment.

Main Results:

Successful diagnosis and treatment of conditions including subglottic hemangioma, tracheal webs, papillomatosis, granulomas, and neoplastic growths.
Effective debulking, excision, and biopsy of diseased tissues from the vocal cords to the trachea.
Demonstrated particular efficacy in neonatal and infant airways when used with rigid telescopes.

Conclusions:

The tracheoscope provides excellent airway control for complex procedures.
It facilitates safe and effective endoscopic laser treatment of various tracheal pathologies.
Its application is especially beneficial in pediatric airway interventions.
