Vocal Fold Injection

This is another surgical option to manage hoarseness or aspiration caused by a unilateral (one-sided) vocal cord paralysis where a “plumping” material is injected into the immobile vocal cord. Similar materials are used in cosmetic surgery to fill wrinkles and lines in the face.

The injection is done under general anesthesia with no associated incision in the neck, since it is placed through the mouth with the assistance of a microscope/telescope. The procedure takes about 10 minutes to perform and the child is typically sent home the same day.

The voice tends to be more strained for the first couple of weeks after the procedure, but then should improve. The result is not long term. The injection lasts about two months to one year, depending on the material used.
