Using a new perforator, the authors have developed a new dual-floor burr-hole method for use in deep brain stimulation therapy. The modification is called "dual-floor" because the usual 15-mm-diameter burr hole, which is located centrally and reaches the dura mater, is surrounded by a 4-mm-wide rim that is also planed downward by the new perforator to a depth of 4 mm. This dual-floor burr hole is adjusted to fit the burr-hole ring and cap that are are supplied by the electrode manufacturer. Such a method eliminates bulging of the scalp just over the burr-hole ring and cap. In addition, it is helpful for securing a tight fixation between the burr-hole ring and the skull.
作者使用一种新型穿孔器，开发出一种用于深部脑刺激疗法的新型双层骨孔方法。这种改良被称为“双层”，是因为通常位于中央且直达硬脑膜的直径15毫米的骨孔，被一个4毫米宽的边缘环绕，该边缘也由新型穿孔器向下刨削至4毫米深度。这种双层骨孔经过调整，以适配电极制造商提供的骨孔环和帽。这种方法消除了骨孔环和帽正上方头皮的隆起。此外，它有助于确保骨孔环与颅骨之间的紧密固定。
