Stroke (cerebrovascular accident) is an acute brain injury caused by blood vessels. Every year, about 800,000 people in the world have a first or recurrent stroke. Of which, Vietnam has about 200,000 people with stroke each year. Stroke is the third leading cause of death and the leading cause of disability.

In the cold season, especially during the changing seasons, there are many cases of facial paralysis and mouth distortion due to paralysis of the 7th cranial nerve. Although the disease can recover quickly, it can easily leave aesthetic sequelae if not detected and treated early.

Sudden facial distortion is a common symptom when the weather turns cold, causing many people to panic about this abnormal condition of the body. However, in reality, the disease is not life-threatening and will be cured after about 1-3 months if diagnosed and treated early. In addition, the most worrying thing about the disease is the complications of movement and aesthetics later if not treated early.

The facial nerve or cranial nerve VII is the nerve that controls the movement of the muscles of the face and neck of a person to perform movements such as frowning, closing the eyes, smiling, whistling or puffing the cheeks, etc. Each muscle fiber on the face expresses subtle emotions controlled by these nerves.

I fell off my bike and was bedridden for 4 months. My memory is normal. I could move my right arm for the first 6 months, and my left arm for the next 6 months. It has been almost 4 years now, and my right arm is normal, but my left arm is a bit weak. I cannot bend or lift my legs. What should I do to be able to walk normally again?

Endoscopic surgery to decompress the nerve to treat facial paralysis is a difficult technique that requires high skills of the surgeon, the surgery time is quite long although this method is not too complicated. The purpose is to control the airway during surgery and resuscitation after surgery. Except in cases where the patient has central nervous system damage with poor self-awareness.

Parotidectomy is indicated in some cases such as parotid gland tumors, parotid gland inflammation due to stones... Parotidectomy will mainly preserve the VII nerve. However, the parotid gland is where the VII nerve divides into small branches that control the facial muscles, so sometimes in cases of malignant tumors, it can cause invasive damage to the VII nerve that cannot be preserved during surgery.

Total parotidectomy with VII nerve preservation is a type of surgery that removes the entire tissue of the parotid gland outside the body without affecting the VII nerve. They have the effect of maintaining sensation and movement of the facial muscles. Total parotidectomy with VII nerve preservation under laryngeal mask anesthesia is increasingly popular in difficult cases.

Hemifacial spasm is a condition in which one half of your face is affected. It usually starts with twitching around one eye. Although it is not a serious condition, it can be disruptive to your daily life.

Cold-induced hemiplegia mainly occurs in winter and spring, regardless of age or gender. The disease affects health, causing difficulties in daily life. Rehabilitation of hemiplegia takes a certain amount of time.

Facial paralysis, also known as peripheral facial nerve palsy, is a condition in which the patient loses all or part of the movement of the muscles on one side of the face. The cause of facial paralysis is damage to the facial nerve. Currently, to detect and diagnose facial nerve damage, doctors may order magnetic resonance imaging (MRI) or computed tomography (CT). So, should facial paralysis be treated with MRI or CT?
