Microscopic anterior cervical foraminotomy (MACF) is a surgical technique for unilateral cervical radiculopathy that preserves segmental motion and avoids adjacent segmental degeneration, but little is known of its long-term outcomes. ⋯ Although some radiologic results have shortcomings, the results of this study suggest that MACF has favorable long-term outcomes.

Comparative Study
Endoscopic Endonasal Versus Transorbital Surgery for Middle Cranial Fossa Tumors: Comparison of Clinical Outcomes Based on Surgical Corridors.
Based on our experience with the endoscopic endonasal approach (EEA) and transorbital approach (TOA) for middle cranial fossa tumors, we evaluated the efficacy and limitations of visualization and the clinical outcomes associated with the approaches depending on the surgical corridors. In addition, we determined the optimal strategy for each approach. ⋯ Endoscopic surgery can be considered an alternative with acceptable sequelae and reduced morbidity for the management of middle cranial fossa tumors. Surgeons should be aware of the strengths and weaknesses of each surgical corridor and select the optimal approach for each patient based on the tumor.

Comparative Study
Cage Subsidence and Fusion Rate in XLIF With and Without Fixation.
To examine the subsidence rate in patients undergoing extreme lateral interbody fusion (XLIF) using data from a 2-year retrospective study to assess the effect of supplemental fixation on the stand-alone procedure. ⋯ Supplemental fixation did not significantly influence cage subsidence or SL angle. Only BPS fixation significantly improved the LL angle. The 2-year fusion rate was satisfactory.

Transclinoid-Transcavernous Approach to A Giant Cavernous Sinus Hemangioma: 2-Dimensional Operative Video.
This surgical video demonstrates a transclinoid-transcavernous approach for the resection of a cavernous sinus hemangioma (Video 1). The patient is a 42-year-old woman who presented with headache and blurred vision. Magnetic resonance imaging (MRI) demonstrated an enhancing mass in the right-side cavernous sinus and sella. ⋯ Final pathology was consistent with a cavernous sinus hemangioma. Postoperative MRI demonstrated near total resection except for a small piece of residual in the sella, which was stable in 6-month follow-up MRI scan without further treatment. The patient has been back to normal life and work.

Thromboembolic complications are serious adverse events associated with stenting of intracranial aneurysms. For the development of novel devices, currently no practical model exists to evaluate distal embolic events. The purpose of the current study was 2-fold: 1) assess the feasibility of a porcine carotid bifurcation model for in vivo testing of stent thrombogenicity and 2) compare the thrombogenicity of the Enterprise vascular reconstruction device versus the Pipeline embolization device (PED). ⋯ The swine carotid stent model allows in vivo analysis of device-related thrombogenicity and distal embolic event rates. Size reduction of the perfused rete mirabile indicates the presence of thromboembolic events. Both Enterprise and PED were associated with similar thrombogenicity in this experiment.
