Have you ever felt like one side of your face, perhaps under your eye, is twitching without your control? You can see it in the mirror, but you can't stop it. It's really uncomfortable. Some people call it lip twitching. Today we're talking about a condition called hemifacial spasms, which is uncomfortable for many people, but is usually not dangerous.
What are the symptoms of this condition?
It usually starts very slowly. At first, your eyes, especially your lower eyelid, just start to twitch. It goes away for a while, then comes back. You might think, "Oh, this is just a twitch." But over time, this twitching can gradually increase. The twitching that starts in your eyelids spreads to your cheeks, then your lips. Eventually,
the entire muscle system on one side of your face starts to twitch without your control. Sometimes, the twitching is so severe that it can even seem like your mouth is being pulled to one side.
Imagine how it would feel if you were in an important discussion or talking to someone and suddenly one side of your face started to twitch like this. It's very uncomfortable, isn't it?
There is no pain associated with this condition. However, a person suffering from this can feel very embarrassed and uncomfortable when socializing. This tightness, which comes and goes at first, can
be constant as the condition worsens. These symptoms may increase, especially when you are tired or stressed.
Why is this happening? What is the reason for this?
Simply put, the main reason for this is that a blood vessel presses on a nerve that controls our facial muscles (facial nerve). Let's understand this a little more simply. Imagine that when someone puts their foot on a water pipe, the water flow becomes disrupted. There is a nerve (facial nerve) that comes out of the brainstem and helps our facial muscles move, smile, and speak. When a blood vessel that goes near this nerve presses on this nerve, that is, it starts to press, unnecessary electrical signals start to pass through the nerve. Because of those signals, your facial muscles start to twitch without your control. But this is not always the reason. Very rarely, this condition can also occur due to a cause such as an accident to the facial nerve or a brain tumor.
Who is more at risk?
This is actually a relatively rare condition. It can affect anyone, male or female, at any age. However, statistics show that this condition is more common in women. It is especially common in middle-aged and elderly women
between the ages of 40 and 79. It has also been found to be slightly more common among Asians than in Western countries.
How do you find this, Doctor?
When you see a doctor with these symptoms, he will first examine you carefully and look at the nature of the twitching. If you suspect that this is Hemifacial Spasm, the next step is to do
an MRI (Magnetic Resonance Imaging) scan . This MRI scan does two main things: 1.
Confirm the cause: As I mentioned earlier, this scan can clearly see if there is a blood vessel that is supplying the nerve. 2.
Rule out other diseases: This scan can also confirm that there are no other serious diseases such as a brain tumor or Multiple Sclerosis that are causing these symptoms. Therefore, an MRI scan is a very important step in the diagnosis of this disease.
What are the treatments for this?
There are several effective treatments for this condition. Your doctor will choose the most appropriate treatment for you based on the severity and cause of your condition.
| Treatment method | Description |
|---|
| Botox injections | This is the most popular and successful treatment available. It involves injecting a small amount of a drug called Botulinum Toxin into the twitching muscles. This temporarily paralyzes the muscles and stops the twitching. This treatment needs to be repeated every few months. |
| Microvascular Decompression Surgery | This surgery is recommended for people with severe cases who have not responded to Botox injections. In this surgery, a surgeon inserts a tiny sponge-like device between the nerve and the blood vessel that is pressing on the nerve to relieve the pressure. Although this is a very successful procedure, like any surgery, it is usually used as a second option because it carries some risks. |
| Medications | In some cases, anticonvulsant drugs such as Carbamazepine and Clonazepam, which are used to treat epilepsy, can control these seizures to some extent. |
Are there other reasons for facial drooping?
Yes. Not all facial twitching is Hemifacial Spasm. After your doctor looks at the MRI, if there is no major problem, he will also consider other causes of these symptoms.
- Excessive caffeine intake: If you consume more than 400 milligrams of caffeine per day from things like coffee and tea, muscle cramps may occur.
- Side effects of some medications: Muscle twitching (fasciculation) can occur as a side effect of some medications.
- Stress and fatigue : These are the main causes of conditions like eye strain.
- Bell's palsy : This is a temporary weakness or paralysis of the facial muscles.
- Parkinson's disease : Tremors like this can occur as one of the symptoms of this disease.
- Hormonal imbalance: It can also be caused by hormonal changes in the body.
- Multiple sclerosis: A disease that affects the nervous system.
Therefore,
rather than self-diagnosing , if you have symptoms like this, it is best to definitely see a doctor to find the exact cause.
