Comparative Study
Delayed Height Loss After Kyphoplasty in Osteoporotic Vertebral Fracture with Severe Collapse: Comparison with Vertebroplasty.
To compare clinical and radiographic outcomes and complications after vertebroplasty (VP) and kyphoplasty (KP) for osteoporotic vertebral fractures with severe collapse. ⋯ KP and VP showed similar improvements in pain and disability during treatment for osteoporotic vertebral fractures. Although vertebral height and segmental kyphotic angle were restored significantly in both groups, progressive vertebral HL was inevitable, especially after KP. This likely resulted from the difference of bone-cement interface as a consequence of balloon tamping in KP. Surgeons must consider the respective features of vertebral augmentations.

The aim of this study was to evaluate the clinical features, surgical complications, and functional outcomes of the surgical treatment of patients with cavernous malformations (CMs) involving the medulla oblongata. ⋯ Respiratory dysfunction and deficits of cough reflexes can commonly occur during the early postoperative period for surgical resection of CMs involving the medulla oblongata. Favorable functional outcomes can be achieved by surgery, especially for younger patients who experience fewer hemorrhages and have lesions with perilesional edema and the absence of developmental venous anomalies.

Paraspinal masses are a relatively uncommon but diverse group of lesions that can be neoplastic or non-neoplastic. Peripheral primitive neuroectodermal tumors of the lumbar paraspinal region with diffuse and strong glial differentiation have never been reported before. ⋯ Although these lesions appear to be exceptionally rare, an approach similar to that of intracranial high-grade glial tumors was effective in our experience. Our patient had no evidence of recurrence at 3-year follow-up.

Planned Gamma Knife Boost After Chemoradiotherapy For Selected Sinonasal And Nasopharyngeal Cancers.
To determine the feasibility of a Gamma Knife boost after intensity-modulated radiation therapy in combination with multimodal therapy in patients with nasopharyngeal carcinoma and sinonasal malignancies with skull base or cavernous sinus involvement. ⋯ Planned Gamma Knife boost followed intensity-modulated radiation therapy is feasible, safe, and provides excellent local control in patients with sinonasal malignancies and nasopharyngeal carcinoma, particularly in cases with cavernous sinus involvement. Further follow-up will be necessary to determine the long-term effectiveness and complication profile.

To assess the application of functional neuronavigation in surgeries of adult cerebral gliomas. ⋯ This study confirmed that the application of neuronavigation in adult glioma surgery can improve postoperative quality of life and lengthen the survival time of patients, especially in cases involving the brainstem and the eloquent area.
