Objectives:
To assess the results of endoscopic CO(2) laser resections combined with mitomycin-C and/or triamcinolone acetonide therapy in the treatment of patients with symptomatic subglottic tracheal stenosis.
Materials And Methods:
Eleven patients (all female) with subglottic tracheal stenosis were divided into two groups: six patients with idiopathic subglottic tracheal stenosis and five with subglottic tracheal stenosis of known etiology (four with Wegener's disease and one with polychondritis of the trachea). Three patients showed signs of reflux. The primary outcome measure was improvement of the clinical symptoms and the secondary the postoperative reduction of airway resistance.
Results:
All patients were treated with CO(2) laser resections combined with mitomycin-C and/or triamcinolone acetonide therapy. Postoperative examinations during a period of 7 to 72 months demonstrated a reduction of symptoms and of airway resistance in all patients.
Conclusions:
One or more endoscopic CO(2) laser resections combined with mitomycin-C and/or triamcinolone acetonide therapy are effective in the treatment of subglottic tracheal stenoses. Long-term oral steroid and immunosuppressive therapy as well as the use of proton pump inhibitors positively influences the postoperative outcome.

Tracheostomy
A tracheostomy is a surgically created opening (stoma) in the anterior part of the trachea. It is used to establish a patient airway, bypass an upper airway obstruction, simplify the removal of secretions, permit long-term...

Description of the Procedure
Decannulation refers to the permanent removal of the tracheostomy tube, signaling the resolution of the condition that initially necessitated the tracheostomy. The process requires a well-coordinated interplay between...

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
