Summary
This study introduces a novel bipedicled vocal fold mucosal flap technique for repairing vocal fold defects. The method showed significant voice quality improvements, particularly in mucosal wave and breathiness, indicating a safe and effective surgical option.
Area of Science:
- Otolaryngology
- Laryngology
- Surgical Innovation
Background:
- Vocal fold mucosal defects can impair voice quality.
- Existing repair techniques may have limitations.
- Novel surgical approaches are needed to improve outcomes.
Purpose of the Study:
- To present a new surgical technique: the bipedicled vocal fold mucosal flap.
- To evaluate the efficacy of this flap in repairing vocal fold mucosal defects.
- To assess the impact on voice quality and vocal fold function.
Main Methods:
- Retrospective analysis of 6 clinical cases undergoing the bipedicled vocal fold mucosal flap procedure.
- Auditory-perceptual assessment using the Grade-Roughness-Breathiness-Asthenia-Strain (GRBAS) scale.
- Stroboscopic evaluation based on the European Laryngological Society protocol, analyzing glottal closure, mucosal wave, and phase symmetry.
Main Results:
- Significant postoperative improvement in the mucosal wave parameter (P=0.046).
- Significant reduction in overall dysphonia grade (P=0.025) and breathiness (P=0.025).
- The technique was applied successfully in cases of polyps, cysts, sulcus, and mucosal bridges.
Conclusions:
- The bipedicled vocal fold mucosal flap is a safe and effective technique for vocal fold mucosal defect repair.
- It promotes significant improvements in mucosal wave and overall voice quality.
- The technique has the potential to preserve rheological properties and reduce fibrosis.
