In-office Vocal Fold Injection

When a vocal fold is paralyzed, an in-office injection procedure may be a good option. This can be performed with temporary substances such as VoiceGel or Gelfoam or long-lasting substances such as calcium hydroxylapatite or collagen. The advantage to in-office injections is that no sedation is required, making the procedure very safe. Local numbing medicine is injected in the neck, and the vocal folds are also sprayed with numbing medicine. The injection is performed through the neck while looking at the vocal folds with an endoscope (lighted camera) in the nose. The recovery period is similar to that of other vocal fold injection procedures.
