Endoscopic intervention for subglottic stenosis may improve voice quality, but more research is needed. Current evidence shows potential benefits in voice outcomes, though limitations exist.
Area of Science:
- Otolaryngology
- Speech-Language Pathology
- Respiratory Medicine
Background:
- Subglottic stenosis treatment often focuses on airway patency, with voice outcomes frequently underreported.
- Endoscopic intervention is a common method for managing subglottic stenosis.
Purpose of the Study:
- To systematically review and assess the evidence on how endoscopic intervention impacts voice outcomes in patients with subglottic stenosis.
Main Methods:
- A systematic literature search of PubMed and Cochrane databases was performed.
- Included studies were analyzed for patient-reported outcomes, auditory-perceptual ratings, and acoustic/aerodynamic measures.
Main Results:
- Eight observational studies involving 829 subjects (predominantly female) were analyzed.
- Patient-reported voice outcomes showed inconsistent significance; auditory-perceptual ratings were generally preserved, and acoustic/aerodynamic measures indicated improvement post-intervention.
Conclusions:
- Endoscopic dilation shows promise for improving voice outcomes in subglottic stenosis.
- Evidence limitations and heterogeneity necessitate further research with standardized, validated voice outcome measures and rigorous methodology.
