Case Reports Comparative Study
Functional identification of the primary motor area by corticospinal tractography.
For quick and stable identification of the primary motor area (PMA), diffusion tensor imaging (DTI) data were acquired and corticospinal tractography was mathematically visualized. ⋯ Corticospinal tractography enables identification of the PMA and is beneficial, particularly for patients who present with dysfunction of the PMA.

Lateral ventricle tumors: surgical strategies according to tumor origin and development--a series of 72 cases.
Optimal surgical management in lateral ventricle tumors remains controversial. We conducted a retrospective study of patients with these lesions treated with a surgical strategy on the basis of tumor origin: primary or secondary ventricular and associated transependymal development. ⋯ Lateral ventricle tumors can be treated best by careful selection of the approach according to tumor origin and development. Overall, the transcallosal approach is preferred, but in patients with transependymal growth or large primary or secondary ventricular tumors, the transcortical is a better option.

Endoscopic aqueductal stenting via the fourth ventricle under navigating system guidance: technical note.
We report three patients with symptomatic isolated fourth ventricle after ventriculoperitoneal shunt placement for hydrocephalus associated with ventricular hemorrhage. All three patients were treated successfully with our new method of endoscopic aqueductal stenting under navigating system guidance. ⋯ Our method of aqueductal stenting is a reasonable choice for initial treatment of patients with isolated fourth ventricle, and it entails less invasive neurosurgery.

Surgical exposure of the sciatic nerve in the gluteal region: anatomic and historical comparison of two approaches.
To increase awareness among neurosurgeons of alternative surgical approaches to lesions of the sciatic nerve in the gluteal region. ⋯ At the present time, the majority of peripheral nerve surgeons use an infragluteal approach to the proximal sciatic nerve. However, for select patients with well-defined and localized lesions, the transgluteal approach may provide sufficient nerve exposure with lowered operative complexity and postoperative morbidity.

Comparative Study
Exposure of midline cranial base without a facial incision through a combined craniofacial-transfacial procedure.
A single-stage combined craniofacial-transfacial approach that exposes the midline cranial base without visible facial incisions is described. ⋯ Large anterior cranial base lesions can be resected and excellent cosmetic outcomes can be achieved with a single-stage combined transfacial-craniofacial approach that exposes the entire midline cranial base and requires no facial incisions.
