Summary
This study presents a new surgical technique using posterior cricoid grafting for neurogenic vocal fold motion impairment. The procedure widened the airway and improved voice quality in three patients.
Area of Science:
- Otolaryngology
- Laryngeal Surgery
- Vocal Fold Dynamics
Background:
- Impaired vocal fold motion can stem from cricoarytenoid joint fixation, bilateral vocal fold paralysis, or interarytenoid scarring.
- Conventional surgical methods often involve arytenoid lateralization or resection for airway enhancement.
Purpose of the Study:
- To evaluate the efficacy of posterior cricoid grafting in treating bilateral reduced vocal fold motion of neurogenic origin.
- To assess airway improvement and voice outcomes in patients undergoing this novel surgical approach.
Main Methods:
- The study details three cases of neurogenic bilateral vocal fold motion impairment treated with posterior cricoid grafting.
- This technique aims to create a wider resting position for the vocal folds and arytenoids.
- Acoustic and aerodynamic voice analyses were performed.
Main Results:
- All three patients experienced significant airway improvement following the procedure.
- Encouraging voice results were observed, with symmetric vocal folds and no new scarring.
- The larynx remained suitable for future electrical pacing.
Conclusions:
- Posterior cricoid grafting is a promising surgical option for neurogenic vocal fold motion impairment.
- The technique offers advantages including vocal fold symmetry and preservation of laryngeal function.
- Preliminary results suggest improved airway and voice, warranting further investigation.
