Why is the left recurrent laryngeal nerve more vulnerable to damage?
Relationship of the recurrent nerve to the inferior thyroid artery.
The nerve often passes anterior, posterior, or through the branches of the inferior thyroid artery.
Medial traction of the thyroid lobe often lifts the nerve anteriorly, thereby making it more vulnerable..
Where does the left recurrent laryngeal nerve arise?
The left recurrent laryngeal nerve arises from the vagus to the left of the arch of the aorta. It curves inferior to the aortic arch and ascends in the groove between the trachea and the esophagus.
What is the function of the recurrent laryngeal nerve?
The recurrent laryngeal nerve (RLN) branches off the vagus nerve (cranial nerve X) and has an indirect course through the neck. It supplies innervation to all of the intrinsic muscles of the larynx, except for the cricothyroid muscles, as well as sensation to the larynx below the level of the vocal cords.
Where does superior laryngeal nerve come from?
The superior laryngeal nerve (SLN) originates commonly from the vagus nerve at the level of the C2 vertebra and descends medially toward the thyrohyoid membrane (TM), the membrane between the thyroid cartilage and the hyoid bone .
Can a paralyzed vocal cord repair itself?
If your vocal cord paralysis symptoms don’t fully recover on their own, surgical treatments may be offered to improve your ability to speak and to swallow. Surgical options include: Bulk injection. Paralysis of the nerve to your vocal cord will probably leave the vocal cord muscle thin and weak.
Where is the recurrent laryngeal nerve?
The recurrent laryngeal nerve (RLN), also known as the inferior laryngeal nerve, is a branch of the vagus nerve (CN X) which has a characteristic loop around the right subclavian artery on the right and the aortic arch on the left before returning up to achieve the tracheoesophageal groove and then the larynx.
How do you treat a recurrent laryngeal nerve injury?
The treatment methods include the medicines (neurotrophic medicines, glucocorticoids and vasodilators); ultrashort wave therapy, acupuncture and moxibustion and others; voice training, vocal cord injection and others; reinnervation methods of the unilateral RLN injury (including RLN decompression, end to end …
What happens when the recurrent laryngeal nerve is damaged?
Injury to the recurrent laryngeal nerves can result in a weakened voice (hoarseness) or loss of voice (aphonia) and cause problems in the respiratory tract. Injury to the nerve may paralyze the posterior cricoarytenoid muscle on the same side.
Is laryngeal paralysis progressive?
“Laryngeal paralysis” is a progressive disease that leads to suffocation. A severe cyanotic episode can lead to death. “Polyneuropathy” means multiple nerves are affected, most notably in the larynx (recurrent laryngeal nerves), but also in the esophagus and hind legs.
What nerve can be damaged during thyroidectomy?
These are the recurrent laryngeal nerve and the external branch of the superior laryngeal nerve. Damage to a recurrent laryngeal nerve can cause you to lose your voice or become hoarse.
What causes recurrent laryngeal nerve paralysis?
In 134 patients with recurrent laryngeal nerve paralysis, the left recurrent nerve was most commonly involved. Malignant neoplasms of the lung and pulmonary tuberculosis were the most frequent causes of the paralysis.
What is laryngeal nerve damage?
Laryngeal nerve damage is injury to one or both of the nerves that are attached to the voice box. Laryngeal nerve damage can be caused by injury, tumors, surgery, or infection. Damage to the nerves of the larynx can cause hoarseness, difficulty in swallowing or breathing, or the loss of voice.
What is laryngeal level?
Location. In adult humans, the larynx is found in the anterior neck at the level of the C3–C6 vertebrae. It connects the inferior part of the pharynx (hypopharynx) with the trachea.
How long does it take for your vocal cords to heal?
You need to allow time for your vocal folds to heal before returning to full voice use. If you are a singer or do use your voice a lot, you may need four to six weeks of careful voice use for a full recovery, he says.
Can a damaged larynx be repaired?
In some cases, 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.
