We sought to study the application of precise intraoperative localization of small intramedullary spinal cord tumors. ⋯ The application of the multimodal image fusion combined with intraoperative O-arm image navigation system can be used to localize small intramedullary tumors.

Disc herniations at the cervicothoracic junction (C7-T1 level) are unusual, and there have only been a few studies of patients with herniated C7-T1 discs. In addition, previous studies did not focus on the mechanism and causes of solitary cervicothoracic junction disc herniation. The authors investigated the characteristics, symptom duration, clinical course, and biomechanics of cervicothoracic junction disc herniation by comparing patients with C7-T1 disc herniation (C7-T1 group) with control groups. ⋯ C7-T1 disc herniation demonstrates unique characteristics. Understanding the features of disc herniation at the cervicothoracic junction would be helpful for optimal care.

The fusiform gyrus and the collateral sulcus are the anatomical structures located in the temporobasal region. In this study, the topographic anatomy of the fusiform gyrus and the collateral sulcus is detailed to make a contribution for a successful course of temporal lobe surgery. ⋯ The topographic anatomy of the collateral sulcus with its surrounding structures is detailed in this study. This study clarifies and supplements the knowledge presently available to help develop a more feasible surgical concept.

Temporal bone tegmen defects may be associated with cerebrospinal fluid (CSF) otorrhea. A variety of techniques have been used for repair. We report our experience with skull base reconstruction for tegmen defects using either autologous or alloplastic grafts. ⋯ CSF otorrhea due to tegmen defects can be repaired via a middle fossa craniotomy using either an autologous or alloplastic graft with equivalent outcomes and efficacy, although alloplastic graft helps reduce operating time.

To evaluate the effects of preoperative simulation based on patient-specific vertebral models, and computer-assisted designed drill navigation templates in expansive open-door laminoplasty (EOLP). ⋯ Drill navigation template and preoperative simulations in EOLP are technically feasible. With the help of templates and preoperative simulation, shorten operation time, accurate trough positioning, decrease incidence of hinge fracture and could be acquired. This technique should be further studied and affirmed in clinical applications.
