The choice of block location should depend on the extent of the lesion and the response to treatment. The general principle should be from superficial to deep, from simple to complex, from terminal to nerve trunk and nerve root. Nerve disruption Radiofrequency temperature-controlled thermocoagulation for nerve disruption is the most direct and effective method of treatment. Nerve destruction treatment also includes medial thalamus stereotactic radiation therapy (gamma knife or X-knife), surgical subdural crestal crestal medullary dorsal root destruction treatment, pituitary destruction, sympathetic trunk ganglion destruction, etc.
