A new, versatile adapter for computed tomography-guided stereotaxis is presented. The instrument consists of a light aluminum frame, which by means of a nasion support and two ear plugs is fixed to the patient's head. Reproducibility of repeated fixations is very high. The adapter is fitted to most stereotactic frames and can be used in all adult patients. Comparison between computed tomography- and ventriculography-guided determinations of thalamic targets showed a mean difference of 0.6 and 0.7 mm for the x and y coordinates, respectively. The z coordinates seldom showed any measurable difference. We now perform all types of stereotactic neurosurgery (tumor biopsy, implantation of depth electrodes, thalamotomy, dentatotomy, cingulotomy, etc.) with computed tomography guidance only. The short-term results in a small number of patients have been at least as good as after conventional ventriculography-guided surgery. In addition to open stereotactic surgery, the adapter is also suitable for external stereotactic irradiation of intracranial targets with a linear accelerator.
介绍了一种用于计算机断层扫描引导立体定向的新型通用适配器。该仪器由一个轻质铝框架组成，通过鼻根支撑和两个耳塞固定在患者头部。重复固定的可重复性非常高。该适配器适用于大多数立体定向框架，可用于所有成年患者。计算机断层扫描引导与脑室造影引导确定丘脑靶点之间的比较显示，x和y坐标的平均差异分别为0.6毫米和0.7毫米。z坐标很少显示出任何可测量的差异。我们现在仅在计算机断层扫描引导下进行所有类型的立体定向神经外科手术（肿瘤活检、深度电极植入、丘脑切开术、齿状核切开术、扣带回切开术等）。少数患者的短期结果至少与传统脑室造影引导手术的结果一样好。除了开放式立体定向手术外，该适配器还适用于使用直线加速器对颅内靶点进行外部立体定向放射治疗。
