Trigeminal neuralgia, commonly known as “face pain”, is a kind of severe pain like electric discharge that occurs repeatedly in the distribution area of the trigeminal nerve in the face. The onset of trigeminal neuralgia is very intense and unbearable, and some patients describe the pain as worse than death. There are many treatments for trigeminal neuralgia, including medication, surgery, radiofrequency ablation, and Chinese medicine. In recent years, the technology of gamma knife surgical treatment has advanced by leaps and bounds, and with the accumulation of treatment cases, its efficacy has been more and more affirmed. Which trigeminal neuralgia patients are suitable for gamma knife treatment? Gamma knife is a combination of stereotactic technology and radiation therapy technology, its principle is to focus gamma rays on the pain-related nociceptive conduction pathway, thereby blocking the abnormal conduction of nociception and achieve the effect of analgesia, while not affecting the normal motor function of the trigeminal nerve. After more than 50 years of clinical validation, Gamma Knife has become an important treatment tool in neurosurgery. What are the indications for Gamma Knife treatment of trigeminal neuralgia? 1.Patients with intractable trigeminal neuralgia who are ineffective after drug treatment or who cannot tolerate the side effects of drugs; 2.Patients of advanced age, combined with chronic diseases such as diabetes, hypertension and heart disease, as well as those who are in poor general health and cannot tolerate surgery; 3.Patients who are afraid of surgery and worried about postoperative complications; 3.Patients who are ineffective after other treatments or who relapse after treatment; 4.Patients with secondary trigeminal neuralgia that The primary lesion has been dealt with, or the primary tumor is small; The above trigeminal neuralgia patients are suitable for choosing Gamma Knife treatment. When doing Gamma Knife, the patient needs to wear a head frame like a hat. In order to fix the head frame, several cranial nails need to be screwed into the patient’s skull and the head frame is fixed to the patient’s head through the cranial nails. The screwing process requires local anesthesia and is otherwise non-invasive. It is safer, less risky, less traumatic and less painful than surgery. At the same time, Gamma Knife treatment is time-saving and simple, the patient only needs to do the necessary checkups and examinations before treatment, no shaving, no significant pain, the entire treatment course generally takes only 1 to 2 hours, most of the disease treatment only once, the same day or the next day after treatment can be discharged.
