Overview
- Trigeminal neuralgia is extreme pain and muscle spasms in the face. Attacks of intense, electric shock-like facial pain can occur without warning or be triggered by touching specific areas of the face. Although the exact cause of trigeminal neuralgia is not fully understood, a blood vessel is often found compressing the nerve. Medication, injections, surgery, and radiation may be used t…
Treatment
- Trigeminal neuralgia treatment usually starts with medications, and some people don't need any additional treatment. However, over time, some people with the condition may stop responding to medications, or they may experience unpleasant side effects. For those people, injections or surgery provide other trigeminal neuralgia treatment options.If your condition is due to another c…
- There is no specific test for TN, so diagnosis can take time. Treatment depends on the cause and severity of the condition. Several medications are available to provide relief from pain and to decrease the number of episodes. Sometimes surgery is required. Medication can provide relief from pain and reduce the number of attacks. The first form of treatment is typically anti-seizure …
- Rhizolysis In this approach, part of the trigeminal nerve is inactivated temporarily by using one of the following methods: a heated probe, an injection of the chemical glycerol or a tiny balloon that is inflated near the nerve to compress it. During the procedure a needle or a tiny hollow tube called a trocar is inserted through the skin of your cheek. These procedures provide immediate relief i…
- The initial treatment of trigeminal neuralgia is medical, with carbamazepine and/or gabapentin.Large surgical series have confirmed that microvascular decompression of the trigeminal nerve root is an efficient and durable treatment for trigeminal neuralgia 4.Other treatment procedures include: 1. gamma knife surgery (focused at the trigeminal root in the pos…
Symptoms
- The pain can be brought on by mild stimulation of the face, such as brushing your teeth or shaving. Its often described as feeling like electric shocks or stabbing. People with TN may initially have short, mild instances of pain, but over time they may experience longer, more frequent attacks of intense pain. Most people with TN experience symptoms in cycles pain com…
- 1. TN involves pain on one side of the face that is innervated by branches of the trigeminal nerve. 2. The pain is brief and sharp in nature, and most commonly occurs in the cheek or jaw. 3. The pain is reported as an “electric shock” like sensation, lasting seconds. 4. Rarely, pain can occur on both sides. 5. During severe attacks, there can be associated twitching, tightening or spasm of t…

- TN diagnosis is based on the description of symptoms and examination. TN patients often have normal neurological exam. If there are bilateral TN symptoms, numbness in the trigeminal nerve distribution, or younger age of onset, then further evaluation may be needed.Patients often undergo a brain MRI with contrast to rule out a structural cause of TN. Other specialized imagin…
What Are The Causes
- Compression of the root of the trigeminal nerve by an abnormally positioned blood vessel is commonly implicated as a cause of trigeminal neuralgia. The pressure on the nerve causes it to misfire, resulting in pain. Occasionally, the compression is caused by a tumour, and often there is no obvious cause found. Other, rarer causes of trigeminal neuralgia include multiple sclerosis an…
Epidemiology
- According to the National Institute of Neurological Disorders and Stroke, although anyone can get TN, its more common among women than men. Its also more common in people over the age of 50, although it can occur at any age.
- 1. TN is the most frequent type of facial pain and the incidence has remained constant ranging from 12.6/100,000/year to 27/100,000/year. 2. TN is uncommon in population younger than 40 years (overall incidence of 0.2/100,000/year) and increases in incidence with advancing age, occurring in 25.9/100,000/year in individuals older than 80 years. 3. TN appears to be slightly mo…
- There is approximately an incidence of 4.3 per 100,000 per annum. The vast majority of cases are unilateral, with the right side of the face being affected more commonly (1.5:1). Only about 3% are bilateral. It peaks around age 60 to 70, its prevalence increases with age 1,4. The maxillary branch (CN V2) is the most affected and the ophthalmic branch (CN V1) the least.
Prognosis
- Radiofrequency thermal lesioning usually results in some temporary facial numbness after the procedure. Pain may return after three to four years.
- The condition can progress, with attacks increasing in severity and frequency. In some cases, the pain or ache becomes constant.
- 1. 50% of people with TN experience remissions of at least six months' duration. 2. 65% of people newly diagnosed with TN will have a second episode within five years, and 77% within 10 years. 3. Periods of remission tend to get shorter with time, and attacks of pain get longer.
- Trigeminal neuralgia is not life threatening. It tends, however, to worsen with time, and many patients who initially were successfully treated with medication must eventually resort to surgery. Some doctors advocate surgery such as microvascular decompression early in the course of the syndrome to forestall the demyelination damage. However, there is still much controversy and u…
