Using Three-Dimensional Printing to Create Individualized Cranial Nerve Models for Skull Base Tumor Surgery.
Using three-dimensional (3D) printing to create individualized patient models of the skull base, the optic chiasm and facial nerve can be previsualized to help identify and protect these structures during tumor removal surgery. ⋯ 3D printed models of skull base tumors and nearby cranial nerves, by allowing for the surgical procedure to be simulated beforehand, facilitate preoperative planning and help prevent cranial nerve injury.

Various approaches are advocated for symptomatic thoracic disc herniation (TDH). The aim of this series is to demonstrate the feasibility, safety, and results of posterior transfacet or transpedicular approaches for excision of all types of extradural TDH. We report a consecutive series of patients undergoing posterior approach surgery for TDH. ⋯ TDH including large central calcified discs can be safely removed through posterior transfacet or transpedicular approaches with reduced morbidity in comparison with more invasive anterior approaches. Careful microsurgical technique and use of specialized instruments are important for successful excision of TDH from a posterior approach.

The need for lumbar-lumbosacral fusion surgery has increased in the recent decade. Although this type of surgical approach has been reported to provide better improvement in low back pain compared with conventional conservative treatments, the ratio of failure varies between 5% and 30% in different studies. ⋯ Our study has revealed that lumbosacral fusion surgery increases sacroiliac joint degeneration. We consider that magnetic resonance imaging is superior to computed tomography for detection of early stage sacroiliac joint degeneration.

To analyze postoperative changes in cervical alignment in patients with adolescent idiopathic scoliosis (AIS) with different curve patterns. ⋯ Correlations between the improvement of CL and TK highlight the importance of restoration of patients with normal TK or AIS. Reciprocal changes in cervical alignment may happen if the TK was also simultaneously restored in patients with AIS. For patients with different curve patterns, the cervical sagittal parameters tend to be similar during follow-up.

Embolic occlusions of the common carotid artery (CCA)/internal carotid artery (ICA) and intracranial artery occlusions in acute ischemic stroke are associated with high morbidity and can benefit from endovascular therapy. However, the optimal endovascular strategy for these conditions is unclear. This study aimed to evaluate the feasibility of the pass-thrombectomy-protective thrombectomy (double PT) technique and the clinical outcome of treated patients. ⋯ The double PT technique is feasible and safe in treating initial embolic tandem occlusion of the CCA/ICA.
