Trigeminal neuralgia is a common and persistent disease in neurosurgery, pain medicine and stomatology, which is also called “the first pain in the world” because of the severe pain like a knife cut or electric shock during the pain attack. In the early 1980s, our hospital took the lead in carrying out minimally invasive microvascular decompression with small incisions behind the ear to treat trigeminal neuralgia, and started a series of research on overcoming trigeminal neuralgia. The neurosurgeons of our hospital have accumulated rich surgical experience and enjoy a good reputation in trigeminal neuralgia treatment at home and abroad. However, trigeminal neuralgia is a complex and persistent disease with a very complicated etiology and pathology, and neurovascular compression is still only a doctrine, and microvascular decompression is only one of the various treatment methods. A large number of surgical results at home and abroad show that a small number of patients with trigeminal neuralgia have ineffective surgery or recurrence after surgery, and some other patients with trigeminal neuralgia are not suitable or unwilling to undergo open surgery for various reasons. Transcutaneous puncture selective radiofrequency thermocoagulation is another effective treatment method for trigeminal neuralgia, which has the advantages of less trauma, less cost, quick effect, and can be performed repeatedly. With the strong support from the hospital leadership, our hospital recently purchased the most advanced radiofrequency treatment instrument at home and abroad, and the director of the functional neurosurgery department, Zhao Changdi, led his team to visit and learn from the famous trigeminal neuralgia radiofrequency treatment center for many times. The patients were discharged after only three or four days of hospitalization. The successful development of this project fills a gap in southwest Lu, providing an effective option for some patients with postoperative ineffective and recurrent trigeminal neuralgia, as well as patients with trigeminal neuralgia who cannot or do not want to undergo open surgery for other reasons, avoiding the tediousness of going abroad to receive radiofrequency thermal coagulation treatment in the past, and having great social benefits.
