The coronavirus disease 2019 (COVID-19) pandemic has negatively affected the outcomes of surgical neuro-oncology patients worldwide. We aimed to review the practice patterns in surgical neuro-oncology in low- and middle-income countries (LMICs). We also present a situational report from our own country. ⋯ In our review, we found that the practice patterns in surgical neuro-oncology in LMICs during the COVID-19 pandemic are similar to those in high-income countries, except for a few modifications because of resource limitation and patient preferences.

A need exists to better understand the prognostic factors that influence high-value care outcomes after meningioma surgery. The goal of the present study was to develop predictive models to determine the patients at risk of experiencing an extended hospital length of stay (LOS), nonroutine discharge disposition, and/or a 90-day hospital readmission after non-skull base meningioma resection. ⋯ After external validation, our open-access, online calculator could be useful for assessing the likelihood of adverse postoperative outcomes for patients undergoing surgery of non-skull base meningioma.

The primary objective of the present study was to investigate the correlations among cervical paraspinal muscle morphology changes (fatty infiltration [FI] and muscle atrophy), cervical degeneration, and clinical features in patients with chronic nonspecific neck pain (CNSNP). ⋯ Correlations among the muscle morphology changes, cervical degeneration, and clinical features were established for patients with CNSNP. Muscle volume changes and FI might affect CNSNP diversely through different paraspinal muscle groups. These results imply a complex contribution of muscle morphological changes to cervical degeneration and the clinical course of CNSNP.

Review Case Reports
Ultrafine Flexible endoscope visualization to assist in the removal of a huge spinal extradural arachnoid cyst: a case report and literature review.
Arachnoid cysts are one of the benign spinal cystic lesions. Multiple nerve roots and spinal cord may be compressed by it, and operating is often recommended. ⋯ Here we present a case of giant spinal extradural arachnoid cyst in which a ultrafine flexible endoscope was used to visualize cystic spaces and identity the leaks. We repaired the leak after removing part of the cyst wall under the operating microscope, and the patient had an excellent recovery.

Correction surgery for rigid adult spinal deformity usually involves a complex 360° osteotomy, multiple intraoperative position changes, and staged surgery. Moreover, there is a lack of consensus regarding the surgical strategy for this pathology. We report the technical advantages of a simultaneous anterior and posterior release only in the lateral decubitus position to reduce surgical invasiveness in two case reports. ⋯ Simultaneous 360° segmental release in the lateral decubitus position without repositioning can make it possible to acquire satisfactory correction and reduce surgical invasiveness compared with the conventional procedure for adult spinal deformity.
