What is the largest cranial nerve?
trigeminal nerve
What is the smallest cranial nerve?
trochlear nerve
What cranial nerve makes you cry?
The great (superficial) petrosal nerve from cranial nerve VII provides autonomic innervation to the lacrimal gland. It is responsible for the production of much of the aqueous portion of the tear film.
What is the smallest nerve in the body?
The trochlear nerve is unique among the cranial nerves in several respects: It is the smallest nerve in terms of the number of axons it contains. It has the greatest intracranial length. It is the only cranial nerve that exits from the dorsal (rear) aspect of the brainstem.
What happens if the trigeminal nerve is damaged?
Trigeminal nerve injuries not only causes significant neurosensory deficits and facial pain, but can cause significant comorbidities due to changes in eating habits from muscular denervation of masticator muscles or altered sensation of the oral mucosa.
Can a dentist damage the trigeminal nerve?
Damage to branches of the trigeminal nerve following maxillofacial surgery and dental treatment is unfortunately common, in most cases the symptoms are transient and patients fully recover sensation over time. Persistent nerve damage results in severe complications such as neuropathic pain and trigeminal neuralgias.
Is trigeminal nerve damage permanent?
The good news is that the vast majority of these peripheral trigeminal nerve injuries undergo spontaneous regeneration. However, some injuries may be permanent with varying degrees of sensory impairment ranging from mild numbness (hypoesthesia) to complete anesthesia.
How do I calm my trigeminal nerve?
Many people find relief from trigeminal neuralgia pain by applying heat to the affected area. You can do this locally by pressing a hot water bottle or other hot compress to the painful spot. Heat a beanbag or warm a wet washcloth in the microwave for this purpose. You can also try taking a hot shower or bath.
Who is the best doctor for trigeminal neuralgia?
Teamwork. Mayo Clinic doctors trained in brain and nervous system conditions (neurologists), brain and nervous system surgery (neurosurgeons), and doctors trained in treating children who have brain and nervous system conditions (pediatric neurologists) diagnose and treat people who have trigeminal neuralgia.
What causes inflammation of the trigeminal nerve?
There are inflammatory causes of trigeminal neuralgia because of systemic diseases including multiple sclerosis, sarcoidosis, and Lyme disease. There also is an association with collagen vascular diseases including scleroderma and systemic lupus erythematosus.
What is the most common cause of trigeminal neuralgia?
The main cause of trigeminal neuralgia is blood vessels pressing on the root of the trigeminal nerve. This makes the nerve transmit pain signals that are experienced as stabbing pains. Pressure on this nerve may also be caused by a tumor or multiple sclerosis (MS).
What is Type 2 trigeminal neuralgia?
Type 2 trigeminal neuralgia (TN2) is characterized by constant pain. Characteristically, in TN1, the pain isn’t constant; it comes and goes, and can be set off by touching the skin. It’s not uncommon for a person with TN1 to stop combing their hair or brushing their teeth.
Can you have both occipital and trigeminal neuralgia?
Although referral of pain from the stimulation of occipital and cervical structures innervated by upper cervical nerves to the frontal head of V1 trigeminal distribution has been reported, the development of hemifacial sensory change associated with referred trigeminal pain from chronic occipital neuralgia is extremely …
How long does trigeminal nerve take to heal?
It provides the longest lasting relief, with some studies suggesting that pain returns in about 3 out of 10 cases within 10 to 20 years of surgery. Currently, MVD is the closest possible cure for trigeminal neuralgia.
What is the best medicine for occipital neuralgia?

What triggers occipital neuralgia?
Occipital neuralgia is most commonly caused by pinched nerves in the root of a person’s neck. Sometimes this is caused by muscles that are too tight in a person’s neck. In some cases, it can be caused by a head or neck injury. Chronic neck tension is another common cause.
How do I calm my occipital nerve?
Finding occipital neuralgia pain relief
- Apply ice/heat therapy. Ice therapy may reduce local inflammation and relieve pain.
- Take NSAIDs. Nonsteroidal anti-inflammatory drugs (NSAID) are over-the-counter medications such as ibuprofen (e.g., Advil, Motrin) and naproxen (e.g., Aleve).
- Give yourself a neck massage.
Will occipital neuralgia go away?
Occipital neuralgia can last for a very long time, but it may stop by itself after a while. Generally, occipital neuralgia is a long-term condition that requires treatment to lessen the pain.
What happens if occipital neuralgia goes untreated?
What are the potential complications of occipital neuralgia? Left untreated, complications of untreated occipital neuralgia can be serious or even life threatening. You can help minimize your risk of serious complications by following the treatment plan you and your health care professional design specifically for you.
Is occipital neuralgia caused by stress?
Causes. Occipital neuralgia is caused by damage to the occipital nerves, which can arise from trauma (usually concussive or cervical), physical stress on the nerve, repetitive neck contraction, flexion or extension, and/or as a result of medical complications (such as osteochondroma, a benign bone tumour).
Does occipital neuralgia show up on MRI?
Radiographic imaging is of limited utility in the diagnosis of occipital neuralgia but is primarily concerned with excluding structural pathology of the cord, the spine, the occipital nerves or adjacent structures. As such, MRI is best suited to this task 1,4.
Is there a cure for occipital neuralgia?
Decompression surgery to open the area around the nerve also can be performed. Although a specific cure for occipital neuralgia does not exist, there are many effective symptomatic treatment options.
What irritates the occipital nerve?
Occipital neuralgia happens when there’s pressure or irritation to your occipital nerves, maybe because of an injury, tight muscles that entrap the nerves, or inflammation. Many times, doctors can’t find a cause for it. Some medical conditions are linked to it, including: Trauma to the back of the head.
Can bad posture cause occipital neuralgia?
Posture issues may also cause occipital neuralgia if the patient’s head is often held forward and down, as this position can place excessive pressure on the nerve over time.
Is occipital neuralgia a symptom of MS?
In patients with multiple sclerosis, clinical features in occipital neuralgia that were predictive of the presence of a C2-3 lesion were unilateral episodic symptoms, sensory loss, later onset of occipital neuralgia, and progressive multiple sclerosis phenotype.
