Abstract
Combining the power of stereotactic precision with open craniotomy in a stereotactic craniotomy technique decreases surgical time, morbidity, and postoperative hospitalization. Indications for its use are deep intrinsic masses 3.5 cm or less in diameter; small, superficial lesions otherwise difficult to localize; and lesions associated with motor, visual, or speech areas. Using the standard Brown-Roberts-Wells system allows a) precisely planned cortical entries, b) gross total lesion excisions under direct vision, c) use of probe-guided resection margins, d) small craniotomies through linear incisions, and e) use of local anesthetic alone for resections. The method and results of this universally available and relatively inexpensive technique are discussed in reference to 20 patients. (Neurosurgery 25:572-578, 1989)
