Summary
Fiberoptic bronchoscopy revealed frequent tracheal abnormalities in patients with long-term tracheostomy tubes before decannulation. Tracheal granulomas and tracheomalacia were common, suggesting routine airway examination is crucial.
Area of Science:
- Otolaryngology
- Pulmonology
- Respiratory Medicine
Background:
- Long-term tracheostomy tubes can lead to airway complications.
- Pre-decannulation assessment is essential for patient safety.
Purpose of the Study:
- To evaluate the prevalence of airway lesions in patients with long-term tracheostomy tubes before decannulation.
- To identify common obstructive airway lesions and their anatomical locations.
Main Methods:
- Fiberoptic bronchoscopy was performed on 81 patients with tracheostomy tubes (mean duration 4.9 months) prior to decannulation.
- Lesions were documented, including type, location, and frequency.
Main Results:
- 67% of patients (54/81) exhibited obstructive airway lesions.
- Tracheal granuloma (60%) and tracheomalacia (29%) were the most frequent findings.
- Tracheostenosis (14%) and vocal cord/laryngeal dysfunction (8%) were less common. All lesions were proximal to the stoma; no cuff lesions were observed.
Conclusions:
- A high incidence of tracheal abnormalities exists in patients with long-term tracheostomy tubes.
- Tracheal granuloma is a previously unreported common finding.
- Routine fiberoptic bronchoscopy is recommended for all decannulation candidates to assess airway anatomy.
