Recently, the Department of Neurosurgery of Binchuan Medical College successfully implemented microvascular decompression surgery under the guidance of 3D printing technology for a patient with hemifacial spasm. This marks a new step in the development of sub-discipline of functional diseases in hospital neurosurgery.

A 63-year-old female patient was involuntarily twitched for three years on the right side of the face, and was admitted to the hospital for seven months. The brain magnetic resonance tomography angiography (MRTA) showed that the right facial nerve had vascular compression nerves leading to the facial muscles. Hey. The team of neurosurgical function group led by Professor Li Zefu reconstructed the relationship between nerves and blood vessels in this part by using international advanced 3D printing technology, and successfully guided the implementation of minimally invasive surgery. The patients recovered well after surgery and the symptoms of facial tics completely disappeared.

Latest research: 3D printing technology can be used for minimally invasive surgery

Vascular compression nerve

Hemifacial spasm, also known as facial muscle twitching. For a condition of involuntary convulsions in the semi-lateral part, convulsions are paroxysmal and irregular, varying in degree, which can be aggravated by fatigue, mental stress and voluntary movement, and the patients are suffering. The reason is that there are abnormal blood vessels in the brainstem area of ​​the intracranial facial nerve, and most of them are arteries, which cause oppression of the facial nerve. Medical treatment of hemifacial spasm includes oral medications or topical botulinum toxin injections, but these treatments may be ineffective or temporarily effective and may recur easily after treatment. At present, according to the consensus of experts at home and abroad, the preferred treatment for hemifacial spasm is facial nerve minimally invasive vascular decompression (MVD), which is the most effective and the only possible cure. Minimally invasive surgery can clarify the specific blood vessels of the nerves, apply artificial material polyester cotton pad, pad between the blood vessels and the brain stem, and let the nerves compressing the nerves away from the facial nerve, thereby eliminating the nerve stimulation and reaching the facial convulsion. The purpose of the surgery. The medical 3D printing technology can quickly and accurately print the lesion model according to the patient's individualized characteristics and clinical requirements, and clearly determine the positional relationship of the compressed nerve vessels before surgery, and truly realize individualized and precise treatment.

Juice Drinks

Fruit juice drinks is a beverage made of fruit juice products obtained by physical methods such as pressing, centrifugation and extraction. Fruit juice retains most of the nutrients in the fruit, such as vitamins, minerals, sugar and pectin in dietary fiber. Often drinking fruit juice can help digestion, moisten the intestines and supplement the lack of nutrients in the diet.
There are two kinds of fruit juice: pure fruit juice and compound fruit juice. As far as pure fruit juice is concerned, it can be divided into two types: one is to directly use the original juice, and the other is to dehydrate the freshly squeezed fruit juice first, and then add water to reduce it into concentrated fruit juice. Most pure fruit juices are concentrated. AGOLYN offers various flavors of honey tea, such as honey Citron tea etc.
