Tumors of the lateral and third ventricle: removal under endoscope-assisted keyhole conditions.
Intraventricular tumors usually are managed by approaches and microsurgical techniques that need retraction and dissection of important brain structures. Minimally invasive endoscopic procedures achieve a remarkable alternative to conventional microneurosurgical techniques. Endoscope-assisted microneurosurgery may be a minimally invasive technique with maximally effective treatment. Using the keyhole concept for planning the surgical strategy, the reduction of the brain retraction is achieved, which is one of the main benefits of this technique. ⋯ Endoscope-assisted keyhole neurosurgery seems to be a safe method of removing tumors in all regions inside the ventricular system with a low risk of permanent neurological deficits. The exact surgical corridor planning on the basis of the keyhole strategy offers less traumatic exposure of even deep-seated endoventricular tumors.

Craniofacial resection for cranial base malignancies involving the infratemporal fossa.
Cranial base malignancies involving the infratemporal fossa have been considered unresectable. Advanced operative techniques have made tumor resection feasible in an en bloc fashion with negative histological margins, but there are limited data regarding outcome analysis in patients who have undergone resection of malignant tumors in this area. ⋯ Despite the extensive nature of many infratemporal fossa tumors, they can be resected with acceptable morbidity. Survival rates approach those of anterior cranial base malignancies without infratemporal fossa involvement.

Piezoelectric bone surgery: a revolutionary technique for minimally invasive surgery in cranial base and spinal surgery? Technical note.
Piezoelectric surgery represents an innovative, ultrasonic surgery technique for performing a safe and effective osteotomy or osteoplasty that contrasts with the traditional hard and soft tissue management methods with rotating instruments. ⋯ The present preliminary report (comprising illustrative case reports) demonstrates and introduces for the first time the utility of piezoelectric bone surgery in cranial base and spinal surgery in children. Until now, there has been no documented neurosurgical experience of this technique even in adults.

Transcallosal transchoroidal approach to tumors of the third ventricle.
Although the literature is rich with descriptions of the approach to the third ventricle, surgeons remain cautiously reserved. In this report, we demonstrate that the transcallosal approach can be easily performed provided that preoperative planning is adequate. Familiarity with the course of major cortical and deep draining veins grants the surgeon a wide exposure of the posterior third ventricle. We discuss the indications, surgical technique, and pitfalls to this approach while providing an accompanying video mirroring our discussion.

Medical treatment of Tourette syndrome is often ineffective or is accompanied by debilitating side effects, therefore prompting the need to evaluate surgical therapies. ⋯ Our findings suggest that stimulation of the anterior internal capsule may be a safe and effective procedure for the treatment of Tourette syndrome.
