Intraoperative visualisation of functional structures facilitates safe frameless stereotactic biopsy in the motor eloquent regions of the brain.

Background: For stereotactic brain biopsy involving motor eloquent regions, the surgical objective is to enhance diagnostic yield and preserve neurological function. To achieve this aim, we implemented functional neuro-navigation and intraoperative magnetic resonance imaging (iMRI) into the biopsy procedure. The impact of this integrated technique on the surgical outcome and postoperative neurological function was investigated and evaluated.

Image-guided endoscopic surgery for spontaneous supratentorial intracerebral hematoma.

OBJECTIVE Endoscopic removal of intracerebral hematomas is becoming increasingly common, but there is no standard technique. The authors explored the use of a simple image-guided endoscopic method for removal of spontaneous supratentorial hematomas. METHODS Virtual reality technology based on a hospital picture archiving and communications systems (PACS) was used in 3D hematoma visualization and surgical planning.

A Low-Cost iPhone-Assisted Augmented Reality Solution for the Localization of Intracranial Lesions.

Background: Precise location of intracranial lesions before surgery is important, but occasionally difficult. Modern navigation systems are very helpful, but expensive. A low-cost solution that could locate brain lesions and their surface projections in augmented reality would be beneficial.

iPhone-Assisted Augmented Reality Localization of Basal Ganglia Hypertensive Hematoma.

Objective: A low-cost, time-efficient technique that could localize hypertensive hematomas in the basal ganglia would be beneficial for minimally invasive hematoma evacuation surgery. We used an iPhone to achieve this goal and evaluated its accuracy and feasibility.

Methods: We located basal ganglia hematomas in 26 patients and depicted the boundaries of the hematomas on the skin.

Facial and Cochlear Nerve Complications following Microsurgical Resection of Vestibular Schwannomas in a Series of 221 Cases.

Background: Despite improvements in microsurgical technique and the use of intraoperative electrophysiological monitoring, the potential for facial and cochlear nerve injury remains a possibility in the resection of vestibular schwannomas (VS). We reviewed a series of 221 cases of VS resected via a retrosigmoid approach at our institution from October 2008 to April 2014 and determined the incidence of postoperative facial and cochlear deficits.

Material And Methods: A total of 221 patients - 105 (47.

[High-field intraoperative magnetic resonance imaging suite with neuronavigation system: implementation and preliminary experience in the pituitary adenoma operation with transsphenoidal approach].

Objectives: To review the preliminary clinical experience with high-field-strength intraoperative magnetic resonance imaging (iMRI) suite with neuronavigation system in the pituitary adenoma operation with transsphenoidal approach.

Methods: From March 2009 to December 2010, 31 patients [range, 29 - 76 years, mean age (47 ± 11) years]of pituitary adenoma were operated with transsphenoidal approach and intraoperatively with a movable 1.5 T high-field-strength iMRI suite in combination with neuronavigation system.

[Implementation and preliminary experience of high-field intraoperative magnetic resonance imaging in the endoscopic chordoma operation with transsphenoidal or transoral approach].

Objective: To review the preliminary clinical experience with high-field-strength intra-operative magnetic resonance imaging (iMRI) in the endoscopic chordoma operation with transsphenoidal or transoral approach.

Methods: From January 2009 to December 2010, 23 patients [range, 29 - 64 years, mean age (42 ± 3) years] of chordoma were operated with endoscopic transsphenoidal or transoral approach and examined intraoperatively with a movable 1.5 T iMRI magnet.
