The superior and inferior laryngeal nerves in the throat control the movement and function of the larynx, also called the voice box. Laryngeal nerve damage is injury to one or both of the nerves that are attached to the voice box.
The superior and inferior laryngeal nerves in the throat control the movement and function of the larynx, also called the voice box.
Laryngeal nerve damage is injury to one or both of the nerves that are attached to the voice box.
Significant breathing and speaking difficulties can arise if one or both nerves are damaged due to
A breathing tube in the windpipe (endotracheal tube)
A viral infection that affects the nerves Injury
Tumors
Surgery
Ortner’s syndrome
Treatment depends on the cause of the injury. In some instances, no treatment may be needed and the nerve may recover on its own. Voice therapy is useful in some cases.
If surgery is needed, the goal is to change the position of the paralyzed vocal cord to improve the voice. This can be done with:
Arytenoid adduction (stitches to move the vocal cord toward the middle of the airway)
Injections of collagen, Gelfoam, or another substance Thyroplasty
