Fully Endoscopic Resection of Cerebellopontine Angle Meningiomas.
To describe our operative technique and results from patients who underwent fully endoscopic resection of cerebellopontine angle (CPA) meningiomas. ⋯ Fully endoscopic techniques can be used in CPA meningioma resection with excellent clinical results as an alternative to the traditional open microscopic approach.

From Abstract to Publication in a Peer-Reviewed Journal: Evaluation of the 63rd Annual Meeting of the German Society of Neurosurgery.
The presentation and academic discussion of the latest scientific research is the central purpose of meetings like the annual meeting of the German Society of Neurosurgery (DGNC). The aim of this study was to investigate the publication rate of all oral and poster abstracts of the DGNC meeting 2012 held in Leipzig, Germany, in peer-reviewed journals and to identify factors that are associated with a higher publication rate. ⋯ Overall, 40.4% of all presented abstracts at the 2012 DGNC were published in a peer-reviewed journal indexed in PubMed, which reflects the high scientific standard of this meeting. Prospective studies and studies presented by authors from universities had a higher chance of being published.

Clinical, Radiologic, and Legal Significance of "Extensor Response" in Posttraumatic Coma.
The timely detection of neurologic deterioration can be critical for the survival of a neurosurgical patient following head injury. Because little reliable evidence is available on the prognostic value of the clinical sign "extensor response" in comatose posttraumatic patients, we investigated the correlation of this clinical sign with outcome and with early radiologic findings from magnetic resonance imaging (MRI). ⋯ The correlation of extensor response and loss of pupil function with an unfavorable outcome and with brainstem lesions revealed by MRI is highly significant. Their sudden onset may be associated with the sudden onset of brainstem dysfunction and should therefore be regarded as one of the most fundamental warning signs in the clinical monitoring of comatose patients.

Intraoperative Micro-Doppler in Cerebral Arteriovenous Malformations.
Intraoperative micro-Doppler (IOMD), intraoperative digital substraction angiography (DSA), and microscope-integrated indocyanine green angiography are methods that guide neurosurgical resection of arteriovenous malformations (AVMs) in the brain and minimize the trauma of healthy tissue. In this study we emphasize the use of IOMD in AVM surgery, analyzing the advantages and the limitations of this method. Patients and ⋯ IOMD constitutes a safe, accurate, and low-cost imaging modality for evaluating blood flow velocities and for optimal stepwise AVM elimination without unnecessary sacrifice of veins. PI and RI are reliable parameters in diagnosing cerebrovascular malformations, but systolic and diastolic flow velocities may vary to a greater extent. This phenomenon has never been elucidated previously and therefore needs to be emphasized when using this technique intraoperatively.

Evaluation of Occipitocervical Arthrodesis Rates with Screw-based Fixation and Osteoinductive Fusion Adjuncts.
Occipitocervical (OC) instability may be associated with neurologic impairment and even death. There is a paucity of research on the rate of arthrodesis utilizing modern screw-based constructs coupled with adjuvant osteoinductive agents. We reviewed our experience with OC constructs and compared the fusion rate, functional outcome, and rate of adverse events between recombinant human bone morphogenetic protein (BMP)-2, autologous iliac crest bone graft (ICBG), a combination of BMP and ICBG, and local bone autograft alone. ⋯ Additionally, perioperative adverse events occurred in 23% of cases and did not vary significantly in incidence or severity between fusion adjunct cohorts. We present a large series of patients treated for OC instability with rigid fixation utilizing modern segmental screw-based constructs. The use of adjuvant osteoinductive agents (BMP, ICBG, or a combination) produced equivalent rates of arthrodesis, functional outcome, and adverse events compared with use of local autograft alone.
