Parasagittal meningioma is one that fills the parasagittal angle, with no brain tissue between the tumor and the SSS. Invasion of the SSS is a challenge for complete removal and, consequently, for recurrence of these tumors. The objective of this study was to analyze the factors that influenced the clinical outcome of patients with parasagittal tumors surgically treated. ⋯ Recurrence of parasagittal meningiomas predominated in males, in grades II/III tumors, after subtotal resection, and with more invasion of the SSS. Subtotal or total resections without sinus resection were considered adequate for treating these patients.

Fractionated stereotactic radiotherapy (FSRT) combines the precision of stereotactic positioning with the radiobiologic advantage of dose fractionation. ⋯ Fractionated stereotactic radiotherapy is a high-precision technique. It is safe and feasible in the primary and adjuvant treatment of cavernous sinus meningiomas. Fractionated stereotactic radiotherapy allowed local control in more than 90% of patients.

Comparative Study
Head injuries in adolescents in Taiwan: a comparison between urban and rural groups.
Data pertaining to head injuries in adolescents in Taiwan are scarce. The purpose of this study was to investigate the trend and pattern of head injuries in adolescents in both urban and rural areas in Taiwan. ⋯ The causes, patterns, and outcomes of head injury were statistically different between the 2 age groups of adolescents in urban and rural areas. Further studies on adolescent head injury are necessary.

Clinical Trial
Size and location of ruptured and unruptured intracranial aneurysms measured by 3-dimensional rotational angiography.
The aim of the study was to report about accurate size and location of a consecutive series of ruptured and unruptured aneurysms taking the complex 3-dimensional (3D) anatomy and parent vessel morphology into consideration by using the newly developed 3D rotational angiography (3D-RA). ⋯ An automated calibration procedure applied to all images and excellent visualization of aneurysm and parent vessel morphology using 3D-RA allow accurate size measurement of intracranial aneurysms which may be smaller than previously thought. Small aneurysm (<7 mm), also in the anterior circulation, should be carefully evaluated for treatment.

Head injury is the leading cause of death and disability for patients who experienced a major accident. It has been suggested that a well-planned neurointensive care management can effectively reduce the secondary brain insults. The BTF and the AANS proposed the Guidelines for the Management of Severe Head Injury in 1995. The purpose of this study was to obtain a consensus on whether the guidelines are suitable for treating patients with severe head injury in Taiwan. ⋯ The most beneficial feature of the guidelines was the close control of ICP with an ICP monitor. Patients who received prophylactic sedatives had a favorable outcome (odds ratio, 2.8; CI, 1.0-7.5). There were no significant statistical differences between patients with and those without application of hyperventilation for maintenance of CPP.
