What are the symptoms of laryngeal nerve damage?
Damage to the nerves of the larynx can cause hoarseness, difficulty in swallowing or breathing, or the loss of voice. Treatment depends on the cause and extent of the laryngeal nerve damage. Damage to the laryngeal nerve can result in loss of voice or obstruction to breathing.
How do you test for laryngeal nerve damage?
Tests may include:
- Bronchoscopy. Bronchoscopy. Bronchoscopy is a test to view the airways and diagnose lung disease.
- CT scan of the chest. CT scan.
- Laryngoscopy. Laryngoscopy.
- MRI of the brain, neck, and chest. MRI.
- X-ray. X-ray.
What is laryngeal nerve palsy?
Vocal cord paresis, also known as recurrent laryngeal nerve paralysis or vocal fold paralysis, is an injury to one or both recurrent laryngeal nerves (RLNs), which control all muscles of the larynx except for the cricothyroid muscle. The RLN is important for speaking, breathing and swallowing.
What causes recurrent laryngeal nerve paralysis?
Bilateral RLN paralysis can be fatal. It is mostly caused during thyroid and cervical surgeries, trauma, endotracheal intubation, central brain disorders, diabetic neuropathy, organophosphorus poisoning, myasthenia gravis, and neurodegenerative disorders such as poliomyelitis and amyotrophic lateral sclerosis.
What does a swollen larynx feel like?
Signs of an inflamed larynx are: A low-grade fever. Sore throat. A dry cough.
What happens when the superior laryngeal nerve is damaged?
When the external superior laryngeal nerve is damaged, it results in the paralysis of the cricothyroid muscle, which functions to lengthen, stiffen, and thin the true vocal cord.
Can laryngeal nerve repair?
Methods of immediate intraoperative repair of the RLN include direct end-to-end anastomosis, free nerve graft anastomosis, ansa cervicalis to RLN anastomosis, vagus to RLN anastomosis, and primary interposition graft. Techniques of nerve repair include micro-suturing, use of fibrin glue, and nerve grafting.
What diseases affect the larynx?

What is pharynx larynx?
The pharynx is a fibromuscular tube that extends from the base of the skull to the oesophagus. The larynx is an apparatus made of cartilages, muscles, mucous membrane and ligaments that guards the entrance to the lower respiratory passages such as bronchi, trachea and lungs. Larynx also houses the vocal cords.
