Trigeminal neuralgia is also known as “the first pain in the world”, and the pain is unbearable. Ms. Ao, who has been suffering from the disease for 15 years, has been tortured by the pain, taking medication to control it, but the effect is repeated and no improvement. After microvascular decompression surgery, the pain disappeared! Name: Ayy Gender: Female Age: 76 Admission: The patient was admitted to the hospital with the main cause of “recurrent pain on the left side of the face for 15 years”, which became an electric shock-like sharp pain, and the symptoms did not improve significantly with medication, and she had been treated with acupuncture, which did not have any significant effect, and the symptoms gradually aggravated, and the left side of the face had a trigger point, and there was no significant resistance from the neck. She came to our hospital for further diagnosis and treatment, and was admitted to the outpatient clinic with “left-sided trigeminal neuralgia”. Preliminary diagnosis: 1. Trigeminal neuralgia (left side) Treatment: After admission to the hospital, relevant examinations and assessments were completed, the patient had indications for surgery, and there were no contraindications for surgery in the preoperative examination, so the left trigeminal microvascular decompression was performed under general anesthesia. After the operation, the patient was given the treatment of infection prevention, hemostasis, nerve nutrition and fluid replacement. After the operation, the patient’s left facial pain symptoms basically disappeared, and Prof. Wang instructed that the patient’s condition was stable and he could be discharged from the hospital after the examination. Discharge diagnosis: 1. Trigeminal neuralgia (left side) Discharge instructions: 1. Discharge with medication: none; 2. Advice to the patient: advice to pay attention to rest and strengthen nutrition after discharge; 3. Health education: appropriate exercise, avoiding exertion; 4. Follow-up time: follow up in discomfort. After the microvascular decompression surgery, Ms. Ao, the pain on the left side of the face disappeared, and the disease that had been bothering her for 15 years was cured after the surgery, and she would no longer worry about the recurrence of the disease as she did with the medication. “Microvascular decompression surgery can achieve a one-time cure, and even when there is a delayed cure, there is often no need to continue taking oral medications to relieve symptoms. In most patients, symptoms disappear immediately after surgery. Only a few patients, due to severe nerve damage, require a period of neurologic recovery, during which symptoms gradually resolve.”
