The patient was a 79-year-old female with left-sided facial pain for 8 years. Numerous daily episodes of 1-2 minutes each, ineffective with oral carbamazepine and closure therapy. Previous hypertension, cardiac arrhythmia, and cerebral infarction. We performed percutaneous puncture hemimelia balloon compression, and the pain disappeared immediately after the operation and was discharged in 3 days. Trigeminal neuralgia closure, balloon compression and microvascular decompression are routinely performed in our hospital. Currently, only a few hospitals in China perform this technique — percutaneous puncture microballoon compression (PMC) The percutaneous puncture microballoon compression (PMC) technique was first reported by Mullan and Lichtor in the 1980s as a treatment for trigeminal neuralgia. Its efficacy is comparable to other percutaneous techniques, such as radiofrequency thermocoagulation and glycerol injection, and even to microvascular decompression, and it is valued worldwide by the neurosurgical community because of its safer and faster operation and the fact that patients can undergo it painlessly under general anesthesia. All patients had immediate pain relief, a cure rate of about 92%, an incomplete recurrence rate of about 10-20% within 5 years, and an intact corneal reflex. However, all patients have mild to moderate postoperative loss of ipsilateral lateral sensation. The advantages of PMC are: (1) as an interventional technique, PMC avoids the complexity and danger of open surgery, while greatly reducing the patient’s hospital stay and treatment costs; (2) the principle of PMC treatment is to selectively damage specific nerve fibers related to nociceptive transmission, thus minimizing the possible sensory complications and ocular complications associated with nerve rhizotomy.
