Overview
This is a novel application using laryngeal EMG signals to guide the injection of hyaluronic acid (HA) into the muscle of a paralyzed vocal fold in order to improve the glottal closure and voice of patients with unilateral vocal fold paralysis (UVFP). Compared with conventional vocal fold injection via laryngoscope guidance, our innovation involves performing vocal fold injection with injectable needle electrode which avoids airway irritation induced by laryngoscopy monitoring. The injectable needle electrode localizes the muscle of the paralyzed vocal fold by detecting abnormal EMG signals. The existence of abnormal EMG signals such as fibrillations when the patient is silent or variable recruitment reduction when the patient phonates a vowel also helps to predict the prognosis of vocal fold motion recovery. This innovative strategy is a simple but effective treatment, which allows prediction of prognosis and routine collection of EMG data for further clinical research on UVFP in one shot.
Features
No Anesthesia, No Complications, Satisfactory effect.



Service Procedure
1. Pre-injection vocal fold motion evaluation and voice record.
2. Laryngeal electromyography-guided hyaluronic acid vocal fold injection for unilateral vocal fold paralysis.
3. Post injection follows up.
Notification
The injection pain is tolerable. Anticoagulant medication should be stopped at least one week before the injection.
