”Toothache is not a disease, but pain really kills”, this is an old folk saying. Many patients once the toothache appears, the first thing they will think of is to go to the hospital to find a dentist to see what happened to their teeth. But there is a kind of toothache, pain is more unpleasant than toothache, but is not a dental disease, today I will through a typical case to introduce you to this disease. The toothache is a painful one, but the extraction is fruitless. Xu, a 62-year-old farmer, lives a simple but peaceful life. This day, as usual, she worked in the field, tired of sitting on the ground to drink a sip of cold water, suddenly felt the right side of the root of the upper teeth like a few pinpricks of feeling, she thought, “the teeth will soon be bad, have to brush the teeth”. The next day, Xu’s teeth again felt “zapped” a few times, the third day, the fourth day …… from then on, this needle-like pain like a shadow. The first just eat hard food or eat cold food will appear, and then developed as long as a touch face, a mouth, the pain will quietly find the door, and more and more heavy, as in the teeth installed on the electric door, a touch on the heart of the pain. She told her husband about this, and he took her to the county hospital’s stomatology department to have the painful tooth extracted. However, the pain did not go away after the extraction, but became more severe, and the surrounding teeth also followed the pain. For several days in a row, the pain became more and more severe day by day. She finally couldn’t stand it anymore and begged the doctor to pull out the three good teeth around her. Although the tooth was gone, the pain was still severe. She thought to herself, “This is bad, there must be a big disaster coming, otherwise why does the pain get worse and worse? As the pain was triggered by talking, the person who loved to talk and laugh avoided meeting her acquaintances for fear of further tooth pain, and even woke up occasionally from sleep with tooth pain. The pain was unbearable and I sought help from witchcraft. Half a year had passed, but the toothache did not ease, but worsened, and the pain in the upper lip and the right side of the face also followed. A kind-hearted neighbor said he had to burn incense and ask the gods for blessing, and said that Liu Half-immortal of Lin Village could possess the thousand-year-old fox fairy, which could be spiritual. Xu rushed to the village to find Liu half-immortal, Liu half-immortal muttered and calculated for a while, suddenly shouted bad, said she had bumped into the “fox fairy”, the fox fairy “hit the mouth”, and the recent blood disaster, must be in the seventh day of the seventh month ” Avoid the stars” a day, in order to escape this disaster. On the seventh day of the seventh month, Xu’s home windows and doors closed tightly, covered with black cloth, dare not go out half a step. This difficult day finally passed, the poor Xu Mou where to think of teeth or a burst of pain, her heart beating more and more powerful, the heart panicked, thinking that this is going to be a big deal. Xu was not willing to find Liu half-immortal, this time Liu half-immortal God possessed mumbled for a long time, “fox fairy down” for a while, said Xu is a thistles possessed in the East Mountains, she accidentally bumped the thistles fairy, he got angry and attached to you. If you want to invite the thistle fairy away, you must ask Liu half immortal to her home to exorcise the ghost, or the whole family will have a bloodbath. Xu was terrified, according to the Liu half-immortal, invited a few gods to the home to “exorcise the ghosts”, these gods and drink tossed a few days, the home tossed a bottom up, spent a lot of money. But the toothache remains, the face does not dare to wash, teeth do not dare to brush, even the meal do not dare to eat, really make the person is not human, not ghost, Liu half immortal finally no way. Xu Mou only burn incense and worship Buddha every day, begging all the gods and goddesses, but still to no avail. One day, a doctor said that this is a disease called “trigeminal neuralgia”, a nerve disease, eating carbamazepine effective, but can not go to the root. Knowing this news, she began to seek medical help everywhere, Chinese and Western medicine, Chinese acupuncture, physical therapy have tried, is not working. After 6 years Xu finally gave up hope. After another 2 years, one day a nephew called, saying that this disease has a cure, Beijing Aviation General Hospital neurosurgery with surgery to treat this disease. Xu went to the aviation hospital in March this year to receive the surgery and returned home 8 days after the surgery. There is a toothache from trigeminal neuralgia trigeminal neuralgia, also known as the “world’s first pain”, severe pain, as if a person on the big torture, the incidence of 182/100,000, more common in middle-aged and elderly people over 40 years old. Pain is the most prominent manifestation of the disease, and it is very painful when the pain attacks, such as cutting, burning, needling or electric shock, and there is often no aura before the attack, and it occurs and stops suddenly like lightning. More than half of the patients can have “boarding point”, and the slightest stimulation such as talking, eating, touching, brushing teeth, etc. can cause seizures, so that patients act with extreme caution and even fear. After the seizure period, the natural interval can last from several months to several years. In the 1960s, Gardner-Jannetta et al. proposed the theory of “vascular compression of nerves”. After years of clinical practice, this theory has been confirmed, and under the guidance of this theory, tens of thousands of trigeminal neuralgia patients around the world have been relieved of their pain through “microvascular decompression (MVD)” every year. With the accumulation of experience and the advancement of microsurgery technology, the surgical effect and safety have been greatly improved compared with the early days. At present, thousands of patients with trigeminal neuralgia are treated in the hospital every year, and the cure rate is as high as 95%.
