Skull lesions are rapidly identified and easily removed. Anatomic accuracy consists of maintaining the preoperative target position as much as possible during surgery. Measures that could lead to excessive change in brain volume, such as mannitol, lasix, hyperventilation, and lumbar drains, should be minimized and titrated to need. Maneuvering the probe around the resection bed while observing the monitor provides feedback about possible residual tumor. In a similar manner, the probe can aid in determining when a gross total volumetric resection is complete.
Closure time is minimized, since bone and skin incisions are smaller.
A direct visual path must exist between these two components. He was neurologically normal after institution of corticosteroids. Systemic evaluation revealed a primary lung carcinoma. A small lazy-S skin incision and trephine craniotomy were performed to expose the tumor. A complete tumor resection was performed and the patient was neurologically intact after surgery.
