Dual-floor burr hole adjusted to burr-hole ring and cap for implantation of stimulation electrodes. Technical note.
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.
