What is 11th cranial nerve palsy?
Last reviewed 10/2021. Accessory nerve palsy is paralysis of the muscles supplied by the accessory nerve, cranial nerve XI. Clinical features include: possible loss in function and muscle mass in the trapezius and the sternomastoids.
What does cranial nerve 11 assess?
11th Cranial nerve
The 11th (spinal accessory) cranial nerve is evaluated by testing the muscles it supplies: For the sternocleidomastoid, the patient is asked to turn the head against resistance supplied by the examiner’s hand while the examiner palpates the active muscle (opposite the turned head).
What does cranial nerve 4 control?
This nerve is the fourth set of cranial nerves (CN IV or cranial nerve 4). It is a motor nerve that sends signals from the brain to the muscles. CN IV works with the oculomotor nerve and other eye muscles to control eye movement.
What is 4th cranial nerve palsy?
Fourth nerve palsy means that a certain muscle in your eye is paralyzed. It is caused by disease or injury to the fourth cranial nerve. In children, it is most often present at birth (congenital). In adults, it is most often caused by injury. Many cases of fourth nerve palsy are idiopathic.
What happens if cranial nerve XI is damaged?
Supranuclear lesions of the eleventh nerve cause moderate, often transient, impairment of function of the sternocleidomastoid and trapezius muscles, due to the bilateral innervation. In the spinal cord the nuclei can be involved in amyotrophic lateral sclerosis, syringomyelia, polio, and intraspinal tumors.
What muscles does cranial nerve 11 innervate?
The muscles innervated directly by the XI nerve are the trapezius and the sternocleidomastoid, in addition to the laryngeal musculature (in collaboration with the vagus nerve), such as the palatal, pharyngeal, laryngeal muscles.
How do you test XI nerve?

What would happen if cranial nerve 4 was damaged?
Three of these cranial nerves, cranial nerve III (3), cranial nerve IV (4) and cranial nerve VI (6) are responsible for all of the eye’s movements. Problems with these nerves can cause issues with eye position and movement including eyes turning in, turning out, or being vertically misaligned or causing double vision.
How is 4th nerve palsy diagnosed?
To diagnose fourth nerve palsy, your eye doctor will first conduct a full medical history. Your eye doctor will then examine the functioning of the cranial nerves by looking at the position of the eyes at rest, and then evaluating eye movements as an object is followed with the eyes.
Does 4th nerve palsy get worse with age?
Congenital cases usually do not cause double vision in childhood, and a head tilt may be the only symptom. A person may adapt an abnormal head position, usually tilting of the head to one side, which allows better alignment of the eyes and helps prevent double vision. The head tilt may get progressively worse with age.
How successful is 4th nerve palsy surgery?
The success rate for initial surgery was 84% and was increased to 96% with a second intervention.
Can cranial nerve damage be repaired?
Treatment. If a cranial nerve is completely cut in two, it cannot be repaired. However, if it is stretched or bruised but the nerve remains intact, it can recover. This takes time and can cause a variety of unpleasant symptoms including tingling and pain.
What are the symptoms of 4th nerve palsy?
Fourth nerve palsy generally affects only one eye, but it can affect both eyes as well. The most common symptoms of fourth nerve palsy include: Double vision (diplopia) when both eyes are open. Strabismus, or an eye turn that causes the affected eye to turn upward.
What is the position of the eye with 4th nerve palsy?
Individuals with a right fourth nerve palsy will have their right eye positioned higher than the left. This misalignment is worse when tilting head towards right. Individuals with a right fourth nerve palsy will typically maintain a left head tilt to permit normal ocular alignment and binocular vision.
How long does it take for 4th nerve palsy to heal?
Most cases resolve within weeks to months, with the vast majority completely recovering by 6 months. Some cases may resolve slowly over the course of a year. Patients with head trauma were less likely to recover, yet 44% of these patients experienced gradual and spontaneous recovery.
How long do cranial nerves take to heal?
If your nerve is bruised or traumatized but is not cut, it should recover over 6-12 weeks. A nerve that is cut will grow at 1mm per day, after about a 4 week period of ‘rest’ following your injury. Some people notice continued improvement over many months.
Can MRI show cranial nerve damage?
Cranial nerve dysfunctions may be the result of pathological processes of the cranial nerve itself or be related to tumors, inflammation, infectious processes, or traumatic injuries of adjacent structures. Magnetic resonance imaging (MRI) is considered the gold standard in the study of the cranial nerves.
What vitamins are good for nerve damage?
Vitamins B-1, B-6, and B-12 have been found to be especially beneficial for treating neuropathy. Vitamin B-1, also known as thiamine, helps to reduce pain and inflammation and vitamin B-6 preserves the covering on nerve endings.
What are the symptoms of cranial nerve damage?
Individuals with a cranial nerve disorder may suffer from symptoms that include intense pain, vertigo, hearing loss, weakness or paralysis. These disorders can also affect smell, taste, facial expression, speech, swallowing, and muscles of the neck.
What is the best food for nerves?
Six Great Plant-Based Foods to Fight Nerve Pain
- Green and leafy vegetables. Broccoli, spinach and asparagus all contain vitamin B, a nutrient important for nerve regeneration and nerve function.
- Fruits. Eat at least one fruit daily to help heal damaged nerves.
- Zucchini.
- Sweet potato.
- Quinoa.
- Avocado.
Can vitamin B12 heal nerve damage?
Vitamin B12 Enhances Nerve Repair and Improves Functional Recovery After Traumatic Brain Injury by Inhibiting ER Stress-Induced Neuron Injury – PMC. The .
How do you treat cranial nerve damage?
The types of treatment options for cranial nerve disorders include:
- Medication.
- Microvascular Decompression (MVD)
- Gamma Knife® Perfexion™ Radiosurgery.
- Supra Orbital and Infra Orbital Peripheral Nerve Stimulation.
- Percutaneous Glycerol Rhizotomy.

Which vitamin is good for nerves?
Neurotropic B vitamins play crucial roles as coenzymes and beyond in the nervous system. Particularly vitamin B1 (thiamine), B6 (pyridoxine), and B12 (cobalamin) contribute essentially to the maintenance of a healthy nervous system.
Which fruit is good for nerve?
Berries, peaches, cherries, red grapes, oranges and watermelon, among others, are loaded with antioxidants, which help to decrease inflammation and reduce nerve damage. Plus, grapes, blueberries and cranberries have been found to be full of a powerful anti-inflammatory compound called resveratrol.
Which vitamin is best for nerve repair?
B Vitamins
Vitamins B-1, B-6, and B-12 have been found to be especially beneficial for treating neuropathy. Vitamin B-1, also known as thiamine, helps to reduce pain and inflammation and vitamin B-6 preserves the covering on nerve endings.
