Recurrent nerve paresis / paralysis

A recurrent nerve paresis or paralysis is a partial or total functional loss of the nerve that control vocal fold mobility. Such a disorder may result in hoarseness, swallowing or breathing problems. Most patients suffer from a breathy voice and reduced loadness when one side is affected and the other side remains intact.
About 10,000 times a year in Germany, the diagnosis “Recurrent paralysis” (recurrent paralysis, vocal cord paralysis, vocal cord paralysis) is provided. A proven method to treat the consequences of unilateral recurrent paralysis is vocal fold augmentation. The further development of implants and surgical techniques opened up new possibilities. Recurrent nerve paralysis is a damage of the laryngeal nerves (recurrent nerves) and leads to laryngeal palsy. As a result, the movement of the vocal cord of the affected side is disturbed. As a result, the vocal sound is breathed, quiet and hoarse. In some patients, only the loud voice is affected. Often there is also a swallowing disorder. All of these symptoms of unilateral recurrent paralysis can usually be treated well with a “augmentation” of the paralyzed vocal cord.

Our voice clinic is highly specialized is diagnosing all reasons and effects of RLN problems and offers state-of-art therapeutical options to regain a mostly normal voice function. Patients come from all over the world for phonosurgical treatment, e.g. injection laryngoplasty (augmentation).

Augmentation

A well-known method for more than 100 years is the so-called vocal fold relining or vocal fold augmentation, in which a substance is introduced into the area at the side of the vocal fold and the vocal cord is thereby displaced to the middle.
This can be done in local anesthesia (through the mouth or through the skin from the outside) or under general anesthesia. There are many different substances available, which differ mainly in terms of their consistency, strength and absorbability over time. Frequently used substances are i.a. Hyaluronic acid and endogenous fat. We use all preparations as well as the body’s own fat and have experience with all implants available on the market.If a paresis has appeared fresh and to hope for a spontaneous recovery, first quickly resorbable substances come into question (resolution selectable within weeks to months). A vocal fold augmentation can then also be considered as a “trial injection” with a resorbable substance. If the paresis has existed for some time or if it is known that the nerve has been permanently damaged – for example, if, according to the surgeon, it had to be resected during a tumor operation (“sacrificed”), then u.U. equal to a permanently effective operation will be performed.

In most cases, this operation is possible on an outpatient basis. We have not seen any serious complications after more than 500 outpatient augmentations.
