Object. The availability of large-array biomagnetometers has led to advances in magnetoencephalography that permit scientists and clinicians to map selected brain functions onto magnetic resonance images. This merging of technologies is termed magnetic source (MS) imaging. The present study was undertaken to assess the role of MS imaging for the guidance of presurgical planning and intraoperative neurosurgical technique used in patients with intracranial mass lesions.Methods. Twenty-six patients with intracranial mass lesions underwent a medical evaluation consisting of MS imaging, a clinical history, a neurological examination, and assessment with the Karnofsky Performance Scale. Magnetic source imaging was used to locate the somatosensory cortex in 25 patients, the visual cortex in six, and the auditory cortex in four. The distance between the lesion and the functional cortex was determined for each patient.Twenty-one patients underwent a neurosurgical procedure. As a surgical adjunct, a frameless stereotactic navigational system was used in 17 cases and a standard stereotactic apparatus in four cases. Because of the results of their MS imaging examination, two patients were not offered surgery, four underwent a stereotactic biopsy procedure, 10 were treated with a subtotal surgical resection, and seven were treated with complete surgical resection. One patient deteriorated before a procedure could be scheduled and, therefore, was not offered surgery, and two patients were offered surgery but declined. Three patients experienced surgery-related complications.Conclusions. Magnetic source imaging is an important noninvasive neurodiagnostic tool that provides critical information regarding the spatial relationship of a brain lesion to functional cortex. By providing this information, MS imaging facilitates a minimum-risk management strategy and helps guide operative neurosurgical technique in patients with intracranial mass lesions.

Late Recognition

ABSTRACT Complications of paranasal sinus infection most often involve the orbit and periorbita. Because of widespread use of antibiotics, intracranial extension of paranasal sinusitis is rarely seen today. Nevertheless, the clinician must be aware of the potential of these complications, as late recognition of this condition and delay in treatment can increase morbidity and mortality rates. An interesting case series of sinusitis with orbital and intracranial complication is presented, which was radiologically evaluated, and was managed by endoscopic sinus surgery with drainage of subdural empyema by appropriate neurosurgical technique. The radiological tools played a very important role in both assessment and timing of surgical intervention. Unparallel role of radiological investigations cannot be overemphasized. The key to successful treatment is aggressive management and the timing for surgical intervention should not be deferred. The patients made full recovery at the time of discharge.

Intervertebral Foramina

Selective dorsal rhizotomy (SDR) is a neurosurgical technique developed to reduce spasticity and improve mobility in children with cerebral palsy (CP) and lower extremity spasticity. It involves the selective division of lumbosacral afferent (sensory) rootlets at the conus or at the intervertebral foramina under intraoperative neurophysiological guidance. First described in 1908, early procedures were effective at reducing spasticity but were associated with significant morbidity. Technical advancements over the last two decades have reduced the invasiveness of the procedure, typically from a five-level laminoplasty to a single-level laminotomy at the conus. As practised today, SDR is an effective treatment for young patients with bilateral spastic CP who are rigorously selected for surgery and for whom realistic objectives are set. SDR has therefore re-emerged as a valuable management option for spastic CP. In this article, the authors review the single-level SDR technique and its role in the management of bilateral spastic CP, with particular emphasis on patient selection and outcomes.

Skull Base Meningiomas

Over the past decade, advances in endoscopic microsurgical techniques have resulted in an increasingly aggressive endonasal approach to tumors of the midline skull base. Meningiomas of the tuberculum sellae are often closely associated with cerebrovascular structures, and their removal has traditionally required a transcranial approach. An endonasal approach offers many advantages, including early tumor devascularization and tumor debulking (without manipulation of the optic apparatus), direct access to the medial optic canal, and a minimal-access corridor. Although recent articles have focused on techniques for reaching and approaching the area of the pathology (how to get there), the authors of this report discuss the technical nuances of endoscopic microsurgery when the operator is already “there.” They describe their 6-step technique for endoscopic skull base bone removal, tumor dissection/resection, and closure. They also augment their description with elaborate illustrations.

✓ Glomus jugulare tumors are discussed with regard to diagnosis and treatment. These tumors, although usually benign, may be fatal because of their location. Therefore, accurate classification by location, size, and the blood supply of the mass is important; use of newer roentgenographic techniques provides key information. Surgical removal is recommended as the treatment of choice. The neurosurgical technique of en bloc excision of glomus jugulare tumors is described and illustrated.
