The requirements for modern psychosurgery are safety and accuracy. Stereotactic techniques give the geometric accuracy and stimulation gives physiological information, which is important in determining lesion sites or at least lesion symmetry. The process whereby focal brain destruction is produced is ideally by a freezing probe, but equally effectively by coagulation. A number of small lesions is thus required. This at present is unavoidable if side effects are to be obviated. Careful continuing assessment of results is necessary to validate any surgical procedure.
现代精神外科手术的要求是安全和精确。立体定向技术提供几何精度,而刺激提供生理信息,这对于确定病变部位或至少病变对称性很重要。产生局灶性脑破坏的理想方法是使用冷冻探针,但凝固同样有效。因此需要多个小病变。如果要避免副作用,目前这是不可避免的。仔细持续评估结果对于验证任何外科手术程序都是必要的。
