Neurosurgical decisions regarding interventions close to brain areas with language-related functions remain highly challenging because of the risk of postoperative dysfunction. To minimize these risks, improvements in the preoperative mapping of language-related regions are required, especially as space-occupying lesions often lead to altered cortical topography and language area reorganization. ⋯ The more detailed subdivision of language-relevant brain areas shown in this study can help to achieve more radical tumor resection without postoperative language deficits.

The purpose of this study was to examine the thoracic inlet angle (TIA) and its related parameters in the cervical and cervical-thoracic vertebrae in patients with degenerative cervical spondylosis (DCS) and explore the association of the TIA, tilt angle of the neck, and tilt angle of the first thoracic spine with the cervical degeneration score. ⋯ Age was positively correlated with thoracic inlet parameters in patients with DCS. Men had significantly higher thoracic inlet parameters than women because the men had higher VHs and IVDHs. However, the TIA was not associated with the level of cervical disk degeneration. The clinical relevance of these findings has not been established.

Combined Transarterial and Transvenous Onyx Embolization of Jugular Foramen Paragangliomas.
Jugular foramen paragangliomas are highly vascular tumors known to have significant venous hemorrhage during resection even after conventional transarterial embolization. The authors report a novel technique to the endovascular embolization of jugular foramen paragangliomas using a combined transarterial and transvenous access for better intraoperative control of blood loss and visualization. ⋯ The initial experience with simultaneous transvenous and transarterial paraganglioma embolization demonstrated the safety of the technique and superior embolic agent penetration. This was supported by our observations during embolization and intraoperatively during tumor resection. Additional patients need to be treated with this technique for better assessment of long-term efficacy and incidence of embolization-related cranial neuropathies.
