For patients with intractable trigeminal neuralgia and facial spasm, they have often been treated with various drugs, closure, peripheral branch surgery and other methods for a long time, and it is difficult to cure the disease for several years or even decades, and the recurrence rate is high, which brings great pain to patients and their families, and brings a lot of inconvenience to work and daily life. The Second Department of Neurosurgery has solved the problem of trigeminal neuralgia and facial spasm treatment by adopting microvascular decompression with small incisions behind the ear. Over the years, we have completed more than 2,000 cases of trigeminal neuralgia, facial spasm and lingual neuralgia, and our technical level has reached the leading level in China and achieved good results. In recent years, we have been improving the surgical approach and innovating a variety of special surgical instruments. We have six national patent surgical instruments, combined with the use of foreign imported neurosurgical microscopes, making the cranial nerve microvascular decompression more characteristic, the operation incision is small, less trauma, maximum protection of normal neurophysiological function, with no blood transfusion, fast recovery, high efficacy. It has the characteristics of no blood transfusion, quick recovery and high efficacy. It attracts patients from 30 domestic provinces and cities such as Heilongjiang, Xinjiang, Guangdong, Jiangsu, Zhejiang, Henan and Shanxi.
